The back light for the gauges on my dash, as well as the knobs for my A/C are completely out. I tried turning the dimmer, nothing. I tried checking the fuses, all work fine. I tried uninstalling my new radio, nothing. I have no idea what to do and am freaking out because I cannot see how fast I am driving in the evening and do not want a speeding ticket. I would also like for my car to pass inspection, and with those lights out it surely will fail.

Yes. My tail lights are working 100% along with my blinkers and everything else. The lights that do not come on are my license plate lights, my dashboard backlight, and myA/C backlight. Any help?

All the three lights you mentioned are on different circuits therefore most probably you have failed bulbs except for the instrument illumination, it could be a faulty meter illumination indicator. Check tthe wiring first.
The license plate lights are directly linked to the taillights so you need to check the bulbs and wiring at rear end.

Did you get an answer for this sax4him? I'm currently sitting at Burger king trying to find where the fuse is and I have pretty much the same issue. All the lights you mentioned plus my cig lighter light and ashtray light. I was just changing the license plate lights i noticed aren't working. New bulbs didn't do the trick for that. And now my gauge cluster is out. Can't find a diagram of the sr5 fuse boxes anymore. Just gonna start plucking I guess.

I ended up searching through the fuses in the daylight and it turned out to be a 20 amp blown fuse in the interior fuse box. Grabbed a spare from under the hood and was good to go.
