SOURCE: 2004 silverado for some reason the heater/ac

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.

When you start the car, the HVAC air control doors are automatically moved to a default position, and then as the engine heats up, the doors are moved to the requested position. Probably a problem with the passenger side electrical air mix door actuator, but could also be the passenger side temperature control. Try changing the setting to see if that has any effect.
You will need the service manual to locate the actuators, to check them and replace if necessary.

When i turn my car from hot to cold or vise versa it sounds like something is disconnected to the flap.can i see a diagram of the flap?


There is a tsb about replacing the secondary heater door for that noise. The door warps and hits the main door. It can also cause the heat control to be inop.The dash has to be removed to replace the door.

Ac compressort had to be replaced because it seized up. AC ran good for 2 weeks then went out, now the heater doesnt want to work half the time. i dont know if its my heater coil, a leak in my ac lines,...


THE BLEND DOOR THAT CONTROLS HOT TO COLD SWITCHING IS STICKING. THE CONTORL HEAD IS ELECTRIC AND MAY BE CAUSING THE PROBLEM. HEAT AND AC ARE 2 COMPLETELY DIFFERENT SYSTEMS EXCEPT FOR THE CONTROLLER UNDER YOUR RADIO. HEATER COIL IS REALLY A HEATER CORE WHICH IS A LITTLE RADIATOR INSIDE THE CAR BEHIND THE DASHBOARD.

2004 f-150 heat control will not switch from defrost to floor


You have a vacuum leak that is not only affecting motor operation but also the correct operation of the vacuum switch controlling your damper. Need to have that matter resolved -check all vacuum hoses and fittings for integrity/tightness. Vacuum switch itself might be leaking!

2004 duramax dual climate control the driver side blows cold


Thankfully it was the drivers side controller! I found the temp control actuator located under the dash almost on the floor. I removed the four screws that held the cover in place then followed the wires to the actuator. removed the wiring harness then the two screws. replace with new part and heat works again!
