Question about 2004 Chevrolet Silverado

3 Answers

Heater only works on passenger side.

On my 2004 chevy silverado ext cab the heat blows hot on the passenger side and cold on the driver side. (it has dual controls) I have also had the opposite problem with the AC. I have always been able to turn the ignition off and on with the AC problem and it would correct its self. But with the heater I have tried everything and I can't get any warm air on the driver side. It's starting to get cold so I would appreciate any suggestions.

Thanks
Steve

There is a motor actuator that moves these doors for hot and cold, two separate ones for either side. the motor unit for drivers side is no good and needs new one. replace this and all will be good.

My 06 silverado sometimes won't givve me heat on the driver side. I found that if I move the slider all the way down before I start the truck, then bring the heat up when it's running, i'll get heat on the drivers side.

Just had this happen today to my 2007 silverado heat on the right side cold air on the left side. After engine was off 15 minutes and restarted heat was on both sides. I'm guessing a relay failed to open door to allow the heat to flow thus blowing cold air.will monitor diligently for a while.

Well had the same issue on my duel climate controll 04 2500HD but changing the heater control solved the different temp.The only other thing would be your mixer door motor.There are two,one for DR side is probibly stuck..As far as the blower motor.The resister should have taken care of that.Sounds like you may have another bad one.May want to take a volt meter to the resister plug in and run you different fan speed just to make sure that you get voltage to the different conecters.

Check movement of vent doors on that side. Sounds like they aren't moving over as they should. (Or hose fell off on passenger side.)

A/C and Heat Driver Side Intermittent Problem


You will need to replace your driver side temp actuator. It is most likely sticking or over travelling. It is located under the dash directly below the a/c control head. It is bolted to the a/c box upside down with two small bolts. Let me know if i can help more.
