Need to have your HVAC system scanned to determine what has failed in that system. Possible blend door for drivers side or maybe the system just needs recalibrated.

I have a 2003 Buick Rendezvous. The drivers side blows hot air and the passenger side blows cold air. The car has that dual zone climate control. I have no clue where to start.


The actuator that 'blends' cold with hot is stuck in the cold position. There are a couple of options. Disconnect the battery, then drive the vehicle around without using the AC for 10 min, if the AC is defaulted to come on after a battery interuption, then shut the car down then turn it on again. You are trying to get the electronic actuator to reset and resume proper function. Another option is to try this: Start the car, adjust the pax side full hot, drivers full cold, wait 30 sec then shut car down, then start car back up and reverse the settings, pax full cold, drivers full hot. In both solutions, the vent actuators are stuck at either the full open or full closed, so you are trying to get it to 'self check' and allow them to resume proper function. After two years, I simply removed them altogether since I live where it is hot an only need cold.works just fine....

I have 2003 GMCHD 2500 and the heater is not blowing hot air, turned off the truck and started it again and it will blow hot for 5 seconds and turn to cold again. have you come across this problem before


It is running a test cycle and getting stuck. There are a couple of options. Disconnect the battery, then drive the vehicle around without using the AC for 10 min, if the AC is defaulted to come on after a battery interuption, then shut the car down then turn it on again.

2004 GMC Yukon blows hot air out of the driver side vents when the AC is on. Cold air come out of the passenger side.


Probably the left temp actuator. The wires in the right I/P junction block could have poor tension also, but it's usually the temp actuator.

With AC on cold, Drivers air full hot & passenger side full Cold


that is a good possibilty, but before I pulled the trigger I would try this first. unhook the battery for 5 minutes, rehook it, now turn the key on, wait for 2 minutes, now start the truck and see if the doors now work. sometimes this works, its worth a try.

2006 Envoy XL - Front A/C not working correctly


Disconnecting your battery on our platform has a habit of blowing actuators. Takes quite a bit of time to replace them, not hard, just takes forever to get to them in the dash.

Blows hot and cold-restart and problem disappears for a while


you need a servicing of the ac condensor, also check that the blower is working or not. your problem will be solved by servicing the condensor.

Rear heat in 2004 gmc yukon blows only cold air when turned to heat. driver heated seat button lights up for only a few seconds and turns off.


I have a 2006 yukon and have had to replace the actuator in the rear heat/ac twice.  It moves a valve that closes the cold/hot ducts.  It is a cheap defective part/design.
