Sounds like you need to reset the actuators that work the heat/air and temp blending doors on the heater as they needed to be turned to the off position before disconnecting the battery.

2004 Chevy Silverado AC is blowing warm air on passenger side.


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

My wife had same problem in 2005 yukon. Turn both temperture controls on dash all the way as warm as they will go, Wait about 1 or 2 mins and turn back to coolest setting. Cleared our problem right up. Do this with car running and air on.

I have a 2004 GMC Yukon and the dual climate zone control in the front has issues. The passenger side works to order and the drivers side blows hot air when the ac is on. Is there a temp sensor out...


Remove the Positive Battery Terminal, leave the Negative Terminal connected.  Wait 30 minutes.  Attach the Positive Terminal.  Verify temperature settings is around 70 degrees.  This procedure has been known to resolve computer settings.
