Question about 2004 Chevrolet Silverado
I have a 2004 Silverado that does'nt have any climate control whatsoever...the blower does'nt operate and you can't hear the doors operating when you move the mode knob to redirect the air. The A/C button and recirculate button still illuminate when you push them however. I have power at the fuse under the hood for the HVAC but the fuses in the dashboard on the driver's side for the HVAC don't have any power...they were replaced just to be sure but still no power there...any ideas? Thanks!
If it is as you say, I should check the body harnesses.
When your Silverado was assembled at the factory, the wire harnesses began and ended at the firewall, among many other places.
Each of those locations had a male & a female plug or socket.
If the Silverado ever had a stress in the area of the harness plugs, they could be loose.
Could also get corrosion if there was road salt if you live up north. A car wreck could cause this, or if someone removed and installed the engine.
Lots of reasons.
God bless your efforts.

Unfortunately the bulbs that light up your climate control are not replaceable and in order to get it to light back up again you need to replace the climate control unit.

Check the dimmer wheel or knob. I do not have the specifics for this model just a general idea. Check fuses first with a test light. Let me know if I can help more. Thanks.

No it can not.
You have a couple of actuators that have gone out. The driver temp control. And the air inlet actuator.
And I don't fallow your statment of "my a/c blower went completely out. I tested the blower and it works fine".
If the blower went out, then what do you mean it works fine? Are you talking about air delivery or it just quits blowing all together?

There is a technical service bulletin for this problem.(tsb# 05-55-003) The blend door inside the heater box is binding and needs to be replaced. Unfortunately, the dash has to be removed and the a.c. refrigerant removed in order to remove the heater box.
I already have purchased the blend door and the linkage for my son,s 2003 Lancer. I will be doing the job in about a week.
I am a professional auto repair tech with 38 years experience. I would not recommend doing this job yourself unless you are pretty good with auto repair work.

first check to see if you have power going to the actuators when you switch the switch to it location if no power replace controller if you have power and no movement from actuators replace actuator. if actuators move remove hvac box and check for broken blend doors.
