Without warning, when using the air conditioner, the driver's side vents will starting blowing hot air while the passenger side continues to blow cold. The hot air is so hot it overpowers the cold air side and the air conditioning must be turned off. If you stop the car and turn the ignition off and restart the car the air conditioning will reset and may not have the problem reoccur for days or it may malfunction again within minutes.

We've been told by a mechanic that the problem is a faulty blend actuator door and his estimate to repair was $400.

The drivers side would get hot while the passenger side was cold. Turning off and on the car reset it. I was told the actuator was bad. Took to my mechanic and he confirmed. $500 labor to tear the dash apart and about $265 for the part. My mechanic recommended to replace the passenger side as well to save the $500 labor again and I did this as my 04 Tahoe did the same thing, but got hot on both sides, but that was under warranty. Seems like a common problem
