Question about 2004 GMC Envoy
Response to the previous post....Hi, it will blow hot muggy air if it sat there for 20 min. Even with the windows down. The only time it will get cold is when you start moving. Also the vehicle has stalled a few times with the ac on. If i go into a store and come back out it starts all over again. The vehicle does not stall all the time. Mostly when at idle speed. Sometimes it will hesitate when letting off of the brake. Other than that the motor runs fine all the time. Thanks
This is your head gaskets, it has all of the common signs of it.
Have the head gaskets replaced and the problem will go away.
