Answer . \nOn any automotive A/C system there is one basic rule. The line that leads from the compressor to the interior of the vehicle is always the Low side. The line that runs from the compressor to the front of the vehicle is always the high side.
Answer . low pressure side is located closest to the front of the vehicle on the right side as you are facing the engine it shoulh have a screw on cap with the letter L for low pressure.
Follow the tubes from your ac compressor, the low pressure connector for the r134a freon is larger than the hi pressure connector and should be near the accumulator.
What should you do if your air conditioner in a 1995 Ford Contour is pushing out hot air and no longer cold air What could it be?
Answer . Its most likely the refrigerant. Most places will service air conditioners for around 40-50 dollars.
Answer . What is the outdoor temp? If above 90 this is typical pressures.. It sounds as if you have a dirty filter or some other restriction. Possibly a dirty condenser coil or evap coil.. >>>>>. This means it is HOT in the house, assuming R-22 is the refrigerant. A dirty filter would not cau…se this. (MORE)
\n. \n Answer \n. \nWhen you say too high, just how high is it and what is the high side pressure. It is not uncommon\nfor the suction pressure(lowside) to get up to 80psi on a very hot day. You cannot determine what\nis wrong unless more information is provided.\n. \nIt could be that your… system is overcharged, but without the high side pressure and the temp of the \nsuction line it is hard to give the right answer.

Answer . Usually at the passenger side rear by the firewall next to drier/accumulator Large hose
Answer . Depends. What Year ? On Most Of 1996 And Later It Is On Top Of The Compressor. These Use R134A. If Your Isn`t That Design And Uses R12 Follow The Large Line This Is The Low Side. You Should Locate It That Way. Best To Let A Good Garrage Service Your A/C You Most Likely Will Be Better Of…f. GOOD LUCK (MORE)
NO. IN ADDITION; . If the unit is on its side or upside down, the oil can run out of the compressor and it will seize up. They do make a vertical air conditioner to fit into the taller windows which open side to side.
Just had the serviceman here for that reason. You probably have a leak in your cased coil and the freon leaked out, they will need to run a test that can take up to 48hrs. I'm getting that done after summer for the temps here are already reached 100+.
In the back of the engine compartment, behind the engine, next to the fire wall..
Answer . It will always be on the larger of the two hoses, near the compressor and will have a plastic cap on it with the letter L
Answer . maybe overcharged, or return air leaks (the hotter the return air the more the low side pressure)
Answer . i have a Z24. dont have that problem but i would say your cooling system should be flushed out..your engine is working to hard to run the compresser..hope it helps steve
Answer . This just happened to my Durango. You have 2 fans under the hood to cool the engine and a/c evaporator. One of the fuses under the hood fuse box is blown for 1 of the cooling fans. You will be able to see the metal in the fuse is broken/burnt.
What would cause almost zero low side pressure but normal high side pressure on a 1999 metro air conditioner?
I am the guy that posted the question. It turned out that the expansion valve was blocked. That makes sense in terms of the pressure readings. But the reason it was blocked was surprising to me. The drier failed and allowed tiny beads to flow throughout the system. I had to have the whole thing flus…hed and actually, it still blocked again. We finally got it though and it works fine now. I strongly suspect that the drier problem was caused by the fact that I put a lot of stop leak plus too much freon. But I am not certain of that. (MORE)
Hard to believe there are people so ignorant that this question was even asked!. A "low profile" air conditioner is one that takes up a smaller amount of window space, as compared with "traditional" air conditioners. It is best on smaller windows, or where you want to maximize the view out of a reg…ular window.. Do a search of "LG GL6000ER" for an example. (MORE)
The Avalanche has dual controls for the air conditioning system. One control operates the driver side ac vents, and the other control operates the passenger side vents.
The low pressure side has the larger of the two sets of metal lines with the smaller of the two fittings. They are designed so that you can only hook up one way. Most can taps will only hook up to the low pressure side. Make sure of your system capacity before you start. Overcharging the system won'…t make it run any cooler and is EXTREMELY DANGEROUS! (MORE)
The low side service port can be found on top of the airconditioner compressor. The low side service port will have a bluetop.
Why does the air conditioner in a 1997 corvette blows hot air on passengers side and cold on drivers side?
Some 1887 Corvettes came with separate driver and passenger climatecontrols. The most likely cause is the control system, running aself test will show if the vent doors are operating properly. Ifthe control is ok then the diverter door system is stuck.,
Passenger side near firewall. Where the small line turns into the big line. FYI, that's where the orifice tube is
passenger side in front of the firewall (look right below the middle of the passenger side wiper blade with the hood open and you will see the valve) it is coming up from a silver line that runs parallel with the vehicle to the left of the engine looking from the front of the car towards the back. O…r stand on the passwenger side look under the hood further in towards the engine than the wheel well and about 8 inches towards the front of the car. Hope that helps. Christy (MORE)
You can run your air conditoner in low votage by using a double booster stablizer which low cut off volt is 135 and High cut off may be 170. As per my experience this is the only one way to run AC in low voltage. Dont try to run AC if this stablized is not supporting it will cause AC damage and Incr…ease your electric bill. It is best to run an AC 1Hour in average voltage rather to run full day with low voltage. (MORE)
If it does what it is supposed to do, like cool the room when it is warm then it is working properly.
The low side fitting is on the accumulator. Knowing how to service the unit is more important. Today's air conditioners require EXACT measurements or you will have problems. That is best left to a certified technician.
it is best to store an air conditioner upright the way it sits in the window. if you must store it on its side be sure to leave it upright at least 24hours so the oil that is in all the lines can settle back into the compressor.
How do you fix 1999 buick park avenue air conditioner blows cold air driver side hot air passenger side?
The best thing would be to scan the vehicle computer and check out what is going on but if that is not possible then check the passengers side temperature control sensor located to the far right side of the glove box.............
It is not possible to seal a hole in a car low side or suction line hose. The pressure of the refrigerant passing that hose will eventually push out the seal. The oil contained in the refrigerant plus the heat will cause the seal to loosen from the hose. It is better for you to have one machined pre…ssed for it will give you a confortable ride and cooling inside the car. (MORE)
the service port is on top the rec-drier on the right side fire wall, its hard to find,
Can't say definitively without knowing the model... most GM vehicles from that year used a Fixed Orifice Tube system, and generally have the low side schrader valve placed on the accumulator.
I get hot air coming out of my air conditioner on the passenger side, while I get cold air coming out the drivers side. Can you tell me why and how do I find the schematic to fix it?
No, the oil will run out of the compressor causing it to seize. An air conditioner can be stored on it's side but if it is allow 24 hours before starting it.
Lack of gas. If you go to Kwik-Fit, they can reboost it for Â£45. Hope this helps :) It cause the air conditioner to get hot because when cool air gets in hot air gets out.This is how its hot.It is also how it cools your house.
if your system can satisfy the thermostat at 75 then yes if you dont want the temperature inside to be lower than 75! Sounds like you have issuses with your unit.
Depending on the year, make and model of this Ford, 80 percent of them will be on the accumulator that is attached to the evaporator next to the firewall and many others will be on the suction side of the manifold on the a/c compressor.............
I found mine on the front center of the engine right by the exhaust manifold shield, it has a black protector cap to unscrew from it. You will need to use a long hose for reaching it from a freon can.
How to Recharge Your Car's Air Conditioner . By Larry Carley . LOW REFRIGERANT . If your air conditioner is not cooling well because the system is low on refrigerant, recharging the system with refrigerant should restore normal operation. This can usually be done with a few cans of refrigerant …and a simple service hose connection.. RECHARGING PRECAUTIONS . First, wear safety glasses to protect your eyes. Also avoid skin contact with refrigerant. The chilling effect of spilled refrigerant can cause instant frostbite on bare skin or eyes!. WHAT TYPE OF REFRIGERANT? . Next, you need to figure out what type of refrigerant your vehicle requires: On 1995 and newer passenger cars and light trucks, the correct refrigerant is R134a. DO NOT use any other type of refrigerant. On most 1994 and older passenger cars and light trucks, the original refrigerant was R12. R12 is no longer available to do-it-yourselfers and is very expensive. When older vehicles with R12 A/C systems need refrigerant, they can be refilled with recycled R12 from other older cars (this requires taking your car to a repair shop for professional service), or with some alternative refrigerant other than R12, or with R134a (which requires certain modifications).. CAUTION: Mixing different types of refrigerants is NOT recommended. Use the same type of refrigerant that is already in the system unless you are converting an older R12 system to R134a or another refrigerant.. WARNING: Flammable refrigerants are illegal. DO NOT use any type of flammable refrigerant (propane, butane or flammable hydrocarbons).. Click here for more information about retrofitting older vehicles with R12 A/C systems to R134a.. LOCATE THE SERVICE FITTINGS . Next, you need to locate the service fittings on the A/C system. There are two: a LOW side fitting and a HIGH side fitting. The LOW side fitting is usually located on the suction hose or line that goes from the accumulator to the compressor. The HIGH side fitting is located on the line that goes from the compressor to the condenser.. R12 Low Side 7/16 in. threaded Ã ---------- Ã R134 Low Side 13mm Quick-disconnect . R12 High Side 3/8 in. threaded Ã ---------- Ã R134A High Side 16mm Quick-disconnect . On older R12 systems, the LOW and HIGH pressure service fittings are screw-type Schrader valves. On newer R134a systems, the LOW and HIGH side service fittings are quick-connect style fittings. The LOW pressure fitting is SMALLER than the HIGH pressure fitting.. RECHARGE PROCEDURE . 1. Connect the recharge service hose and valve to a can of refrigerant. 2. Turn the valve on the service hose to puncture the top of the can. 3. SLOWLY turn the valve back out to release a small amount of refrigerant into the hose. This will blow air out of the hose (which you do not want in your A/C system). 4. Close the valve so no more refrigerant escapes, then quickly connect the other end of the service hose to the LOW pressure service fitting on the A/C system. CAUTION: DO NOT connect a can of refrigerant to the HIGH side service fitting. The operating pressure inside the A/C system when it is running may exceed the burst strength of the can, causing the can to explode! This should be impossible to do because the service hose for recharging the A/C system will only fit the smaller LOW pressure service fitting. Even so, you should be aware of the danger. 5. Hold the can UPRIGHT so no refrigerant liquid enters the service hose. You only want VAPOR to be pulled into the A/C system (the compressor may be damaged if it sucks in a big dose of liquid!). 6. OPTIONAL BUT HIGHLY RECOMMENDED: You should use a gauge to monitor the recharging process. Though not absolutely necessary, a gauge will help you recharge your A/C system more accurately, and reduce the chance of undercharging or overcharging (either of which will reduce cooling performance). A high pressure A/C gauge can be connected to the HIGH pressure service fitting, or a low pressure A/C gauge to the LOW pressure service fitting, or gauges can be attached to both fittings (that is what professional technicians do). NOTE: Some DIY recharging kits include a low pressure gauge on the service hose or on a trigger-grip style can dispenser. 7. Start the engine and turn the A/C on MAX/HIGH. 8. NOTE: The compressor may not engage if the system is too low on refrigerant. The low pressure cutout switch will prevent the compressor from running if the system is too low on refrigerant (this is done to protect the compressor from damage due to a lack of proper lubrication). The compressor must be running to suck refrigerant through the service hose into the system. So if it is not engaging when you turn the A/C on, you may have to supply battery voltage directly to the compressor clutch using a fused jumper wire. Look for a single wire connector near the front of the compressor, unplug it and hook up a jumper wire to the battery POSITIVE terminal. This should cause the clutch to engage and the compressor to run. 9. OPEN the valve on the service hose so refrigerant vapor will flow from the can into the A/C system. It may take up to 10 minutes or more per can to suck all of the refrigerant out of the can into the A/C system. Feel the air coming out of the ducts inside the vehicle. It should be getting colder. 10. If you are using a high or low pressure gauge (or both) to monitor recharging, look at the gauge(s). LOW pressure gauge: When the reading is between 25 and 40 psi with the A/C running, STOP. The system is fully charged and should be cooling normally. DO NOT add any more refrigerant. If the gauge is over 50 psi, you have overcharged the system with too much refrigerant. High pressure gauge: When the reading gets up around 200 to 225 psi (R12), or 225 to 250 psi (R134a), STOP. The system is fully charged and should be cooling normally. DO NOT add any more refrigerant. NOTE: The high and low pressure readings will vary depending on the system and ambient temperatures (higher temperatures cause higher system pressure readings). Refer to the vehicle manufacturer specifications for normal system operating pressures, and the total refrigerant capacity of the system. Most newer passenger car A/C systems do not hold much refrigerant (only 14 to 28 oz.), so you don't want to add too much if the system is low. One can of R134a typically holds 12 oz. of refrigerant. 11. If the system needs more refrigerant after adding one can, you can add a second can. CLOSE the valve on the service hose, then disconnect the hose from the empty can, screw a new can onto the service hose valve, turn the valve to puncture the new can, then turn the valve all the way back out again so refrigerant can flow through the hose into the A/C system. When you have finished, turn the engine off. CLOSE the valve on the can of refrigerant before disconnecting the service hose from the LOW pressure fitting (in case there is any refrigerant left in the can). Don't vent any leftover refrigerant from the can. Leave the service hose attached to the can with the valve closed so you can save the refrigerant for a future recharge. Remember to replace the plastic caps over the service fittings, and remove the jumper wire from the compressor if you had to jump it to make it run.. IF THE A/C SYSTEM STOPS BLOWING COLD AIR AFTER A FEW DAYS, WEEKS OR MONTHS . If your A/C stops blowing cold air several days, weeks or months after you recharged it, it means the system has a leak and the refrigerant is escaping. You should add some leak detection dye to the system to find the leak. The leak should then be repaired before the system is recharged again; otherwise you are just wasting your time recharging the system over and over again. (MORE)
An air conditioner cools through the compression and expansion of gas (usually Freon). The gas is compressed, and gets hot because of the compression. The hot gas is then sent through a coil, where the heat is blown off with a fan (this is the hot air you're getting on the "outside" of the air con…ditioner). Once the heat has been vented off, the gas moves into another coil, where the gas goes through a small hole into larger tubing, where the gas is allowed to expand again. That expansion causes the gas to cool, and that is once again blown off of the coil. So, to summarize... freon is compressed into a small tube using a compressor. The compressed gas heats up and is vented outside. The gas then goes through a small aperture into a larger, more spacious tube where it expands rapidly and cools. That cools the coil, and the cold air is blown into the room. The gas then returns to the compressor to repeat the process. So, the reason that an air conditioner blows hot air outside, is because it's blowing cool air inside. (MORE)
Reciprocating compressors work much like the engine of your car, in this case, there are pistons and valves that do the work. Low pressure vapor refrigerant is drawn in through the low side valve on the down stroke and then compressed (raising temperature and pressure) and pushed out the high side v…alve on the upstroke. Scroll compressors instead of having pistons have 2 spiral type plates. One plate is stationary and the other orbits around the other. This will create pockets of compressed refrigerant which though the orbital motion are forced to the center exiting through the discharge line. (MORE)
Why does the driver side and middle vents on your 2004 Chevy truck blow hot air while the passenger side is cold when the air conditioner is on?
Any of the following can cause this to happen...... 1. Low on freon. 2. Restricted evaporator. 3. A/C - heating internal door operations incorrect. 4. A/C - heating controller bad.
Pop the hood and its right in front of you, the one closet to the radiator cap, the larger suction hose...
The low pressure port of the A/C system usually has a blue or black dust cap and is located either on the larger diameter metal tubing typically found between the evaporator and compressor, on the compressor itself, or on the receiver drier (orifice tube systems only). The high pressure service port… is found either on the smaller diameter tubing or the compressor and is larger in diameter. Only charge through the low pressure port. There is a web site with a lot of help full information about your auto a/c system check out the link below.. (MORE)
It most likely is low on refrigerant and needs to be recharges. It could be an electrical or mechanical problem, as well. Another reason could be choking of the radiator cooling coils which blow hot air out from the back of your AC. This generally happens if the external part of your room AC is si…tuated around potential choking materials lying loose such as waste, birds feathers etc. The radiator fan sucks such loose material into the radiator coils which get choked, resulting in back-flow of hot air of the radiator into your room. It also adversely affects the cooling cycle as the gas does not get cooled adequately, in the radiator. (MORE)
It will have two pipes one will be cold and one will be hot if one isn't hot or cold like it supposed to be it will be broken if one is hot and one is cold it is working?
At my aerospace job, we heat up the refrigerant tanks while charging with a heat gun. By heating the liquid in the tanks, it is turned into a vapor. I don't fully understand why we do this, but I think it's simply because vapor is easier to pull into the system than liquid. I hope I answered your qu…estion. It was kinda confusing. (MORE)
It is down near the compressor, passenger side of the engine. It is down near the compressor, passenger side of the engine.
The metering device is sensing and adjusting /throttling in many case, it depends on in what part of the operation /cycle this happens? is it at the beginning? or the end? or the whole time? TXV sensing bulbs can lose their charge, the power head too, the position of the sensing bulb should be at 3 …or 9 o'clock not at 12 or 6 due to liquid refrigerant being in the bottom of the suction line at times. During a hot pull down suction line pressures will hunt in times of pulling down a hot room or box . A restriction can do this as well. (MORE)
Why do you charge an air conditioner or heat pump with refrigerant using the low side of the system?
the main reason is because the low side of the circuit is in a suction pulling from service port toward compressor when calling for cooling
It could, the computer will disengage the ac compressor if the engine temp is too high.
