Does a car AC heating function the same way as normal room ACs or Split Units operate such as in reverse cooling operation?
All car ac's work like most any other ac. I don't know of any car ac's that work like heat pumps that both heat and cool. Every car I have seen provides heat thru a heating co…re which is heated from the water circulated from the engine. , EzForJesus
1994 grand am blows heat out of dash vents when set to defog not window vent cool air blows out of window vents when climate control is set on ac which no longer works is this a fuse or module problem?
Answer . \nThere is a small vacuum line for accessories in the engine compartment on top of the throtle position sensor that comes off and will cause this problem. very sm…all hose...look on the intake throtle body for the sensor...it will have other vacuum hoses attached there also but this one is easily overlooked cause its so small. Hope this helps
Why would your Range Rover 2001 start over heating as soon as the AC is turned on It cools as soon as it is turned off The ac is also intermintenly cooling?
Answer . \n. \nI've seen this on P38's where the temp gauge rises when A.C is turned on.\n. \nIt was due to a short on the earth wire (attached to the body under engine)… - temp was not actually rising, just giving a false reading.\n. \nFrom memory the gauge rose further (into the red) if lights were also switched on - further load on the system.\n. \nHope this helps.
Answer . First check that your coolant lines going to the evaporator aren't cap off. the other possibility is that your control knob on the instrument panel may not be exec…uting it's task. checking the heater hose is a DIY task. The control function will require some knowledge. fish
1993 mercury sable radiator cooling fan will not kick on when car heats up only when AC is turned on high what is the problem?
Answer . Could be a bad temperature sensor Usually located at the rear of the radiator about 1/3 down from the top
Answer . this is an incomplete question.only 'yes' or 'no' is possible. If it's getting too hot and there's no heating in the cab, then you need water n antifreeze. Keep i…t topped up! if you are loosing alot of water then find the leak n fix it....it is a silly question
Your 1990 accord over heats in city driving with the AC on if you turn the AC off it cools down it does not over heat at highway speeds?
the ac compressor puts a significant extra load on the motor, so motor has to work harder, creating more heat. at highway speeds, there is a much larger volume of cooling air …flow through the radiator helping keep it cool.. I suggest you give an inspection to the cooling system. I believe the Honda has an electric fan that is thermostatically controlled, do you hear it running when the car is overheating.? If not, check the fan and thermostat.. Also, since the car is almost 20 years old, the radiator may need a little service.
Yes. See "Related Links" below to the Autzone.com repair guide with detailed instructions and photos for replacing either front or rear heater cores. NOTE: Autozone now r…equires free registration to access the repair guides. More than worth the extra effort for these photo/illustrated instructions. Rear Climate Control Problems Be sure to visit the Automotive Forums linked below - an awesome, in-depth review of trouble-shooting rear climate control problems. Answer Replace the rear control switch on the front panel. It's easy to fix and is the problem. Is about $27 from Ford. Pull out the cup holder, remove the two screws, the cover pops out and more screws remove the panel. One screw holds the switch in, remove the electrical and vacuum connectors. That is one possibility. Another is a vacuum leak. Personal experience with help from someone in a forum: Check the plastic hose in the engine compartment on the firewall side of the passenger-side hinge. It can rub against a metal tube (for instance) and eventually wear a hole in the hose. I didn't want to tape it, afraid it might not last in hot engine compartment, or that it might block vacuum. Sales staff at AutoZone gave me ~1" piece of connecting hose. Cut vacuum hose at leak and install connecting hose. Leak wasn't bad enough to affect the front A/C. Answer if the blower is working it is not either blower control you will more than likely just have to replace the climate control directional switch, this switch allows hot or cold air to be directed to the places you want it to go try changing the rear air control switch on your das panel. this happened to me on my 96. or it could be a vacuum leak. more than likely the switch. about 30 bucks at ford Answer I just purchased a used 96 Ford Winstar and it had the same problem. Turned out to be a bad switch in the dash. Also, the switch on that model is run using a vacuum line, mine also had a hole in it contributing to the problem. I'd check that first as it was the entire problem with my air. Hope that helps!!! blender door not working . Ours did the same thing in blowing hot air to the floor even when the AC was on. It is a bad switch on the front of your van- the switch where you can either control the rear climate or switch it to rear control (the one all the way to the right if I remember right). If you are in a pinch and don't want to buy a new switch you can manually manipulate the vacuum lines on the back of the switch. If you take your console cover off and unscrew the plate that fastens the 4 switches to the dash you have access to the wires and vacuum lines. If I remember right there is a yellow and a tan vacuum line that you can pull out from the switch. If you use a piece of small flexible plastic tubing you can put a "jumper" on those two vacuum lines for the summer. I found that a piece of wire insulation works great (strip a piece of wire and use the piece you remove from the wire). For the winter just remove the jumper and the heater will work. Doing this just affects the setting of hot or cold and has nothing to do with the fan speed so everything will work as normal except you have to switch the jumper as applicable for hot/cold. my 1998 windstar was blowing hot air from the rear vents when i turned on the ac and turned on the rear fan from the front controls , the rear fan control the one right behind the drivers seat next to the ear phone jacks did not function so i disconected it and it started to blow cold air.;.; so i have to think it was a broken switch;..;.;wierd huh Answer the vents might be pulled apart and some cold air is being mixed in. if your vehicle is using dual aircon meaning to say a separate evaporator for front passenger and a evaporator system for back passenger then possibly the problem is the expansion valve of the back passenger evaporator system. it is not any more functioning properly and it has to service by a qualified aircon technician to properly removed the refrigerant ,full down the said evaporator system to be able to replace the defective expansion valve. They will have the evaporator clean and install new expansion valve with same capacity as the defective one. After they have installed it and charge the system then you will enjoy a cold ride.
No, the heat pump will also cool the home.
How do I fix the ac when the problem started with a loud click then steam rose from house ac and now ac doesn't cool?
When you say house ac I am assuming you mean the condensing unit outside your home. If you had what looks like steam came out then this was probably refrigerant (freon) that… was venting out through a leak or hole in system. If the noise was more of a pop then a click then one of the terminals of the compressor blew out when your compressor shorted out. all in all ...time to call a service company.
So little information to work with... . Not blowing air?? . Temperature cannot be adjusted or always lukewarm? See "Related Questions" below for more

The AC unit is first blowing out hot air when it kicks on and then it turns to cool Why does it do this and is it a problem?
There probably is no problem. When the a/c first comes on the air in the ductwork is at room temperature, or warmer if the duct runs through an unconditioned space like an att…ic. Once the coil at the furnace has cooled down, it can begin to cool the air that is supplied into the rooms. Try letting the fan on the furnace run continiously while your in a/c mode. You change it at the thermostat. This will give you a more consistant temperature throughout the house and keep air in the ductwork the same temp as in the rooms.

If you are talking about the no air movement at all, then the fan motor or switch is the most likely. An easy check for the fan motor is to disconnect the wires going to the f…an and use extra wire and try a direct 12 volt connection to the fan, if it runs then the switch is the problem. Note: Please test the fan with the vehicle off and isolated from other electrical connections, but you do not have to remove the fan from it's housing.
