The HVAC system has an actuator on the passengers side and one on the drivers side that control mode and temperature. The left side actuator on yours has failed and will need replacing.

Hi..I have a 2004 Chev Avalanche 1500 4x4 5.3litre...I just lost heating on the drivers side-ok on passenger side (has climate controls for both sides)...what is causing this?? big repair?? can I check...


I have had this problem with my 04 Avalanche. It happened when I changed the battery. I replaced the climate control @ $475. When the battery went down another time, the same thing happened only in reverse (warm on the other side) I asked around and found that you can remove the dash trim pnl. and take out x2 screws that hold the controller in place, unplug it for 1 or 2 minuets and reattach. this will "reboot" the controller. I had to preform this procedure 2 times but it fixed the issue @ $0 and is simple. Has worked fine since.

Heat not responding to temp control setting


it sounds to me like the passenger side control knob needs to be exchanged. This or there should be a relay in the line that is faulty. try wiring the driver's side control to the wires coming into the passenger side control. If this doesn't work, then it may be a computer glitch.

Why does my 2004 avalanche not heat up when i am


Check the coolant level. in the winter time It will not over heat very easily but vapor locks can occur and low coolant level will do what your describing ...When you drive the water pump is spinning faster causing coolant to intermittently flow through the heater core so it gets warm then cold at an idle.. also a thermostat that is stuck open will also cause this its also in the cooling system, if the cooling system is full I would replace the thermostat..good luck hope this helps

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.

Duel heat control works on one side, but the other only cold air


you need a new passenger side temp door actuator. Honestly I would have a dealership do this because they can be a bit of a pain especially if you have the console up front in the middle. If you decide to do it yourself first remove the console, and take a good look at the new actuator, then look up under the dash on the side of the heater box and you will find the actuator. make sure it is the right one and DO NOT!! plug in the electrical connector to the actuator until it is securely mounted to the temp door and heater box. Thanks for choosing fixya!! good luck.
