First of all I would find a new mechanic. That is outrageously pricey. Whatever side is blowing the hot air you need to change the temperature control door actuator. These can be difficult to get to and if installed wrong, you will have to jump through hoops to get the actuator ligned back up again. If you replace it; Make sure you bolt the new actuator in BEFORE you plug the connector in. If not, there is a whole long crazy proceedure you will need to do in order to get the actuator ligned up. But seriously if you don't want to attmept this yourself, find another mechanic ! ! Don't quote me on this, but if I remember correctly it should not be any more that 2 hours labor tops plus cost of the part.

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...


I had a similar problem and thought to solve it my adding freon. When I made the connections I was surprised to find that the pressure was already higher than it should be.

Changed plan at that point and vented freon back into safe range. The A/C immediately began blowing cold again on both sides. Found out later that if the A/C had been serviced / filled on a cold day, that on a hot day in Texas it would be too high and cause the issues you noted.

Heater issue, driver side of 2004 Chevy Avalanche


1. Place the ignition switch in the off position.
2. Remove the HVAC/ECAS fuse for 10 seconds or more. It's in the under hood fuse box. Put the temp in full cold.
3. Install the fuse.
4. Start the engine. DO NOT TOUCH THE HVAC CONTROLS FOR LESS THAN 45 SECONDS.
5. Have any codes cleared with a scan tool.

One side air blows cold one side blows hot


GM has a known problem with the electric actuators that operate the blend and temperature doors in the HVAC system. There are 4 or 5 of these in the typical system. Any can start sticking or binding and cause this problem. Sometimes they can be cleaned, or they might need to be replaced. Sometimes resetting the HVAC system controller by disconnecting the battery for 10 minutes, then reconnecting it, will correct the problem.

You need to replace the drivers side temp actuator that is located on the left side of the HVAC box. It is retained by 3 screws and is fairly easy to replace.

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
