    maximum cooling puts the most strain on the motor... basically the computer compensates for the extra drain on the motor by speeding up the idle.



    not a solution but a step toward fixing it.

As it is a general motors product i beleive the relay is right on the compressor. check fuses and any other relays

Why does my pt cruiser blow hot air when a/c or just turning on outside air?


It's probably that the air tubes lines are already hot due to the hot weather(car parked outside in the sun) and it takes 2-5 for the AC to be blowing air at the correct temperature.
Solution: Turn the AC on but reduce the fan speed to bare minimum for the at least 2 min. After that, crank it up and you should be able to enjoy the cool refreshing air.

2000 pontiac grand prix ac problem


If the compressor is working, a mechanic would check the low and high gauge pressure.
The freon has to flow thru the system to work, and the cooling fan draws air thru the condenser to get rid of the heat from inside the car.
If the ac clutch is working but the gauges show equal pressure, the compressor may be faulty.

2000 NISSAN 4X4 P/U A/C SYSTEM WILL BLOW COLD WHEN OUTSIDE AIR TEMP IS COOL, WHEN HOT OUTSIDE AIR BLOWS HOT.


your auxillary fan is not working. this fan is responsible for cooling the freon that is being circulated in your cooling system... check if there are any loose wires in front of the engine bay.

the auxillary fan is located right beside your radiator fan.

Rear air only blows out hot air, front air is fine


I had this problem once, with my 1999 Montana. I topped off the freon and that fixed the problem. If the AC system is low on refrigerant, it won't cool the back area like it should.

The ac blows hot air in the front and cold air in the back


Either the door that controls whether air from the heater or ac is stuck in between or the ac system is having trouble. Minivans sometimes have seperate compressors for the rear and front.

2002 Montana, A/C not cooling. blows hot air.


Sounds like a gas leak..
Most efficient way to handle that is - go to a ac specialist.. They will put more gas in with a die.. Then a week later they will check it again and a floresant light will spot the die - should there be any leaks.. And that way you will know exactly what you are dealing with..

Hope this helps !!
Rate me good ;o)

check to see if ac compressor is turning ,if so look to see if cooling fan/fans are working if not check fuses,and cooling fan relays/if ac is turning and cooling fan/fans are working ,need to put gauges on ac system and check pressures ,if normal ,and ac low side pipe/lines/hoses are cols then it is ur actuator motor for the temp door that is not working

Ac vent problem


Damper/flap for driver's side is probably stuck. Try moving the selector from cold to hot several times. Also, move the recirc/outside air control if the previous doesn't work.
