The actuator motor that controls the temp is most likely not working,the dash will have to be removed to replace it.

I have a 2005 silverado (texas special edition 1500) Only on the driver's side - the air conditioner begins to blow hot air it happens everyday I turn off the pickup and then restart it this...


unfortunately this always seems to be due to the system low on freon. it feeds freon into the pass. portion of the evaporator core first so when it starts to get low you lose cool on the drivers side first. I would go ahead and have an ac service performed and dye added, that way if it goes low again the leak can be found with a black light that illuminates the dye at point of leakage..

I have a 1999 323i BMW. The AC doesnt blow cold (on cool days it blows cool temperature but not common A/C Cold Air, Hot Days it blows Warm/Hot Air). The heater blows warm air but definitely not common...


First things first.....You must have the air conditioning system hooked up to an a/c system machine and then checked for leaks and also read low and high side pressures. If there are leaks then low Freon (R134a) content and low refrigerant oil can cause the a/c system to not engage the a/c compressor which basically means you will not have proper defrost functionality nor regular air conditioning. Most shops, when working with your air conditioning, will install air conditioning dye to assist them in locating leaks and is the first step in diagnosing all a/c systems. Post the findings after thw

Air conditioner blowing hot air on 2002 monte carlo and it has freon in it


car air conditioner blowing hot air is cause by either a leak or a clogged condenser, since it has a freon in it then it might be a case of clogged condenser but this is just a contributing factor, it is possible that the leak is small that you wont even notice that the freon is not enough for the a/c to blow cold air.

The air conditioning doesnt work it just blows hot air even with the ac on. i dont know whats wrong with it if everything needs to be replaced or just something simple. i know nothing about cars


What I would try first is recharge the a/s system, your car came with R12 freon, that type of freon is impossible to get these days, so you will need a retro fit kit to convert it to 134A freon, the kit will have two 134a fittings that screw on to your R12 port, so that the 134a recharge hose will go on, the low side will be the one your add freon through, it will be the thinker hose of the two, the thin one is the high side stay away from that one, you will also need one can of freon (134a), if it works, it might work for a while till the freon leaks out again, then you will have to take it it for repair, but this way you know it's just a leak and every thing else works.Good luck, let me know if I can be of more help.

I HAVE A 1995 SATURN CAR 1.9L AND THE QUESTION IS. THE AC BLOWS BUT ITS LIKE THE HEATERS ON, AND THE COMPRESSER ENGAGES BUT DOESNT BLOW COLD AIR, I CAN SWITCH THE POSITION OF WHERE I WANT THE AIR TO COME...


Most likely the freon has leaked from the system. Replacing it is a fairly simple process, but finding and repairing the leak is expensive (labor wise). Plus, in the States, federal law prohibits non-licensed personnel from working with freon and it's descendants. Find a good AC service shop and get an estimate--you may not need that AC air as much as you thought! Good luck!

Ac blows hot air


Before doing anything I would have the freon level in your AC system checked, freon leaks are quite common and easily repairable by a specialist.
