Nothing new even with the newer ones. You can replace the bulbs in the hvac control if you are good with a soldering iron. Same goes for radio, power window, mirror, Lock switches are all soldered in my 01 tahoe. The cluster bulbs, Head light, wiper, and 4wd switches are replacable no soldering.

To me it sounds like there's a major body fuse somewhere that's blowing to cause this. I'm not sure if the truck has one or if you know what I'm talking about. Some newer vehicles have a very expensive ground/ECM attached to the chassis that can be damaged during a power surge (ie jumpstart).

You checked all fuses under hood, and by the drivers side dash?

yep ...sure did...even the ones under the steerin wheel ..by the brakes

jomulk ive heard of a loose ground wire behind the engine that could be the cause of all the gremlins

The bulbs in my AC panel have burned out, the ones that illuminate the bottom buttons (as in fresh or recirculate, and rear defogger ac buttons).

Anybody know what the P/N for replacement bulbs?

They will need to be soldered. get some desoldering wire to get the old bulbs out.

I had to bypass mine as when I put new bulbs in they still did not work.

ok thanks. Looks like thats a Radio Shack P/N. I also have 272-1154, mebbe those are the slightly larger ones. When I go I will get a handful of both.


Hopefully, new bulbs will do the trick. Just an annoyance not having the ac lights lit up

ok, heres the results of my radio shack trek:

272-1092: These are the super-tiny bulbs that light up whenever recirc, fresh, ac, rear-defog is selected.

272-1154 - These are slightly bigger than the 1092s, are for the backlighting of the switches mentioned above. (This is what I was needing, my orig post wasnt clear.)

Theres a 3rd series of bulbs in the ac control unit, they backlight the ac control panel dials. They are even bigger than the 1154s. Dont know what p/n these cross to.

maybe this will help someone.
