2002 gmc envoy dash vents on driver side blows hot air and passenger vents blow cold air and I cannot get the driver vents to blow cold air, any suggestions???????
The Envoy one day started a clicking noise from the center of the dash when I would start it up. It would last only a few seconds. I started pushing the buttons for the vent operations and it would do it then. After doing some online research and looking under the dash while operating the door I determined it was the mode door actuator (the clicking is the motor in the actuator going bad). I also learned that only the 2002 Envoy had to have a puller to remove the old actuator. After purchasing the replacement part and finding out the price for a puller ($60 ebay -$160 dealer)I thought about a beam clap that can be bought for .89 cents at Lowes or Home Depot in their electrical dept. Taking a grinder I was able to make it fit over the new part and I had to flex the clap so the jack bolt would line up with opening for the shaft, all of 15 minutes. Puller worked like a charm and after about and 1 1/2 hour it was in and everything was operating.

When I start the car it starts in the rear with a tick tick tick sound coming from the ceiling vents. Then it moves to the front vents same tick tick tick, then to the middle console that faces the back seat same tick tick tick occurs. This goes through all 3 zones for about 2 mins every time the car is started. Any ideas out there?

I have be dealing with this same problem since the truck was new. I has a LOUD ticking in the dashboard. If you turn the defroster on and off again, it will stop, only to start back up again.
