in the back of your glove box that you can drop down is a cylinder with a pull on the top that is what makes the hot to cold cold to hot. that might be bad in the back of your glove box that you can drop down is a cylinder with a pull on the top that is what makes the hot to cold cold to hot. that might be bad
heat and a/c barley blowing in back?
Refrigerant is low
That refrigerant oil
Check the temperature control cable
low on refrigerant or the compressor isn't running..
low refrigerant charge?
Low refrigerant charge? Temperature contro set to HOT position?
That typically means that the refrigerant level is low.
AC System probably needs refrigerant added.
If your 1993 Toyota Corolla is blowing hot air, it might have a refrigerant leak in the cooling system. You can try replacing the refrigerant with a kit found at most auto parts stores, but if the leak is large, this fix will not last long. You might also have a compressor failure.
There are three main possible causes to explain why a car air conditioner is blowing hot air. These causes are a worn out compressor, refrigerant leak, and an electrical problem.
Refrigerant leak? Blown fuse? Compressor not starting
Low refrigerant charge? Temperature control cable not adjusted properly?
Most Sunfires have a 'valve' on the A/C unit that you use to fill the unit with refrigerant. I say valve because it looks like a valve, but really its more of a nozzle. All vehicles from the mid to late 90's and on are forced by law to use only R-134a refrigerant. How much refrigerant your cars unit holds can be determined by finding the refrigerant charge label under your hood. It should be located near or above your A/C unit. The easiest way to ensure no mistakes or damages to your unit is to get a professional A/C fill. But the cheapest way is to buy a can of refrigerant (you can find these at most auto stores and even Wal-Mart) and follow the instructions given in the box. It will show you step by step how to add the refrigerant to your unit.
Blown fuse (compressor clutch) refrigerant leak
Usually compressor not running or low on refrigerant. And yes it is supposed to be warm
I have the same problem. Refrigerant is low due to a small leak in the system. They came out and added refrigerant to my system and it worked fine. Now after a long power outage (hurricane IKE) I am having the same problem. It appears I have a small leak in my system and need more refrigerant installed!
Well, the air conditioning system draws the heat out of the passenger cabin, transfers the heat to the refrigerant, superheats the refrigerant, then rapidly transfers the heat from the superheated refrigerant to the ambient air which flows through the condenser fins. This removes heat from the refrigerant, causing it to cool rapidly and drastically, and that cool refrigerant returns to the evaporator, where the blower fan blows over the evaporator, blowing the cooled air into the passenger compartment.
there are 3 main reasons that your a/c is blowing warm during a call for cooling they are 1.the electric resistance heater is on 2. the reversing valve is energized in a Heat Pump, or you are low on refrigerant
you have a vac. leake or the oneway check valve is not working.....
sounds like your freon may be low
A short in the wiring.
try blowing inside the cartridge
you can go to the store and do it your self I disagree. You have neither the knowledge not the proper tools to charge an auto A/C system. Charge it too much and you may damage the compressor. It does not have freon, but had R-134. Take it to a pro. If you have never done it yourself, I recommend taking it to a shop. However, if you are good at reading and following instructions, you can buy a recharge kit that comes complete with R-134A refrigerant, hose(s), gauge and detailed instructions and do it yourself.
Your refrigerant could be low, but that fix all statement may not be it. You may also have some of the parts freezing up, a weak compressor, a thermostat that is stuck on heating mode. Many many things lead to this problem. Best go with a reputable A/C company to do some trouble shooting.
