I have a 2004 Chevy Silverado that does the same thing. I have the dual temperature setting and alot of people are having the same problem. I have read on the National Hwy Safety Commission that there are a lot of complaints for the same thing. Its the actuator, but I don't know how to fix it. When I turn on AC, both sides will blow cold for a few minutes and if I hit a small bump in the road, the driver's side will turn to extremely hot heat and I have to turn off the engine to reset it and it goes back to cold air until I hit another bump in the road. If I am using the heater, it does the opposite, the air goes from hot to ice cold like the AC is on but only on the driver's side. The actuator is inside the vehicle up above the gas pedal in a plastic housing with three screws.

Just blew 129.00 on a new control panel for the heat/ac control dual zone on my 2005 Silverado. (nope can't send it back cuz I demolished the old one to see what made it tick, er not tick) Driver side stays cold, while passenger side works fine. During the summer the air went hot ( only once)while the a/c was working and the blower motor quit working, GM had a recall on the blower motor so thats fine.....just can't get any heat out of the drivers side. Any idea's?- « Previous
