Gauge Lights
 

I know I saw a post like this on here awhile back but cant find it. Any way, my gauge lights they dont work at all. When I turn on my lights, my gauges don't illuminate. Also when I turn on my lights if my ac/heat is on the the lights on that unit turn off. Ive turned the dimmer switch both ways and nothing. Its been like this since I owned the car.

Try checking the fuses first
Or maybe sum of the wires are touching a metal part of the car or or it is being pinched
If all else fails
Check sogi, they have a write up on replacing the dashlights
Its pretty simple
Jus make sure to keep track of all of the screws, ziplock bags helpd out a lot

Best thing (I use) for keeping screws seperated, and from getting lost.......big speaker magnet and metal muffin tray.

Those lights in the heater switches can be a problem. I think they are LEDs. Some of mine have acted up, since I've owned the car for 4.5 yrs. I live with it, cause I don't drive much at night.

Your dimmer switch could be bad. Find a good one off a local car and try it out. I doubt that all of your cluster lights took a dump at the same time.
