Question about 2004 Buick Rainier

1 Answer

2004 Rainier Air conditioning blows cold then hot air.

My 04 Rainier AC works off and on, one minute it's blowing cold air and the next it's turned to hot. I've purged the system and put a vacuum pump on it to remove any air or moisture in the system and then recharged it. I still have the same results, it's cold then it will blow out hot air. Any idea's?

    This is what I found out about my AC unit. In short I had two problems 1) I had a bad high pressure valve. 2) The magnet on the compressor clutch had too much of a gap and was unable to hold the clutch in to keep the flow of the freon moving. The adjustment may last and it may not, time will tell. It not it's a compressor and a dryer and and and.

I noticed my ac in my 2004 Corolla with 138,000 miles wasn't blowing as cold in recent months. I've never had the AC serviced in the 8 years I've owned it. So I used one of those 12 ounce self...


If this was happening to me.... I'd goto an airconditioning re-gas centre and get them to check for gas leaks. In my old commodore the Evaporator Core was leaking and causing some of the issues you have mentioned.

The air conditioning is blowing hot air and the rear air is saying that it is off when the power is turned on to the unit. It is a 2004 Buick Rainier.


The control head may have some issues,this model does,but there is a possible chance the actuator motor that controls the temp door is most likely not working.
