I have a 2004 Chevy Avalanche. The problem is the AC is blowing hot air on passenger side and the drivers side has about 60 degrees coming out. We have had minor problems with this vehicle,like sensor changing. It has approx. 66000 miles. This problem started after replacing original battery this past week. Any ideas? Ive read about problems with actuators. Thanks for any help

Does the vehicle have dual zone climate control, where the driver side and passenger side have different control? Sounds like a blend door issue on the driver side. Why did you replace the passenger side, was it blowing hot too when AC was on?

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

your mode actuator is stuck. try unhooking battery for a few minutes when you hook back up actuators will do a relearn.if this does not work will need to have replaced
