2003 Impala Climate Control knobs and levers won't light up

I have a 2003 Impala. The Climate Control right and left knobs won't light up. The temperature control levers won't light up either. The outside air button, recirculation button and A/C buttons will light up. The rear window defogger button never lights up. Turning on the rear window defogger (it works) causes the outside air button light, recirculation button light, and A/C button lights to go off. I have checked all the fuses in the driver's side and passenger side instrument panel fuse blocks and they are OK. What could be the problem?

    Right and left climate control knobs won't light up. They came back on once but are out once again.

SOURCE: instrument panel lighting

THE bulbs are not replaceble supposed to replace the whole control head. not the brightest idea i know but that is how gm designed it. if you know how to solder you might can pull apart and find some bulbs that solder in and repair it.I have never tried this, the bulbs are soldered onto the board

SOURCE: Tail lights don't work on 1998 Chevy Silverado.

check the wiring from the tailights back to the fuse panel, it sounds like an open connection. if i recall correctly check under the dash on the drivers side near the fuse panel for a bunch of wires in a bundle and look carefully for a wire or two that are cut/shorted/or seperated, you can also check under the drivers side kick panel by the hood release.

SOURCE: Impala has dual climate control. AC blows cold on

with a dual climate control system, it is imperative for a proper refrigerant charge to be maintained. the symptom you describe is a possible indicator of low charge on the system. the ac evaporator core is closest to the right side of vehicle thereby making air feel cooler on that side, on the left side of the vehicle the cooled air has farther to travel and warms up from cabin air before it discharged from the vents. this is the most probable issue for your vehicle...however if the charge is accurate, the issue would be more so in the air temperature doors which is located deep inside the dash...i hope this helps...good luck!

SOURCE: 2004 impala a/c blower not working

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?

SOURCE: instrument panel removal

I suggest you invest in a 1 year subscription to www.alldatadiy.com It is what I used when I disassembled the dash on my car, and is way better than a paper manual. Another tip is to keep some zip lock bags, and a sharpie handy, and seperate and label all hardware that you remove to help your reassembly

2003 mitsubishi climate control stuck


Follow the cable.. It's the white piece that the cable connects to. Some kind of spring doesnt push the white piece forward far enough to select a hot temperature. You can adjust it yourself from the driver's seat at a red light. It feels like flat lever against the dash/transmission tunnel. Push forward for heat, pull back for AC. There's a spring busted or something and the knob can't overcome the required force... Just manipulate it manually. You can see the white lever mechanism clear as day if you open the driver's door, crouch down and look for the big white piece. My guess is that it has a internal tensioner or spring that crapped out.

I replaced the battery but the battery light is still on what do i do to reset it? 2003 Impala


This should have reset when the battery was out, but to reset the monitoring settings: with the key in the on location, or car running, turn off stereo and hold lower large knob in until the stereo display comes on. then use the arrow (left/right) to scroll through settings ei, tire monitor, oil life. alarm horn etc and find what you want then push the large lower knob again to pick it. I hope this helps, it is rather tough to explain in writing. If this does not work, the battery may need a charge prior to installation or connections may be loose.
