A/C backlight going out

Hello all,

I don't know too much about electrical components in cars so I am asking for a little help for a problem that probably has a simple solution. The backlight is starting to go out in my center console behind the A/C knobs, mainly the power knob and A/C button. I posted a picture to get a better idea of what I mean exactly. I'm hoping its just a fuse that needs replacing but like I said, I'm not too knowledgeable with this aspect. Thanks in advance.

I had my entire cluster go out once and I thought it was the bulbs inside the cluster. I later found out my tail lights (specifically my night time lights) weren't turning on. I had done a complete LED conversion of all my interior and exterior lights including my tail light bulbs. Turned out to be the bulbs that were the issue and caused my fuse to blow which was also connected to my AC instrument cluster. After I replaced the LED tail light bulbs everything went back to normal.

For your situation I looks like just one or two bulbs inside the cluster are burning out. If you're lucky you could find a new cluster at an auto wrecker, or if you're really keen I believe there's a video of someone dismantling that exact cluster and replacing the bulbs with cheap Amazon bulbs, but that requires some soldering.

Hope this helps.

I had my bulbs replaced by Bob at http://www.luxte.ch/

It was about $75+ shipping a year or so back. All the junkyard ones will have burned out bulbs and probably cost about the same.

I just replaced the bulbs and bulb covers on my two control center strips. Bulbs and covers were $16 for 12. I had 10 lights out. Did the soldering work myself. It's pretty easy, and cheaper than replacing the entire panels.

JC forum had an entire post on it if I can find it. Attached are pics of the boards and lights.

Hope this helps.

Post #6 & #7 have the best detail:


I used the wired bulbs for mine with the blue covers. Exactly what was used by the factory, at least on mine. I assume all panels are the same, except for some indicators which are small square LEDs.

Pics attached. Purchased from Jackson Lighting / Electric in Jax., Florida.

Lights: #7219 bulb wire terminal base
Cover: # 39-02-5A
