Recently at night my 2000 Impala's instrument cluster remains dimmed at night. I can see the faint glow of the radio and gear selection indicator above the steering wheel and that's it.. Kind of spooky driving at night. I've checked the fuses and all seem ok that I can tell unless I'm missing one. Interior lights, turn signal lights etc still works. Maybe a light sensor or something. Anyone have an idea what this might be? Thanks ahead of time.
I'm gonna go ahead and bump this dead thread as it's on the first page. I had this problem before and it was a fuse* on the passenger side that didn't look blown but was.
I'm experiencing it again and the fuse was definitely blown this time - replaced it and no luck. Lights come on fine and dandy for 5 sec on start then dim down - P is well lit... clusters have no lights. Ive worked nights this weekend so idk if it happens in the day.
Any suggestions? Is there any way to test the dimmer switch?
The dimmer switch does turn on all courtesy lights when clicked but nothing else.
*iirc the fuse is the middle one in the first full row above the relay - i'll get it's name when i get back home.
EDIT: It actually did happen a week ago in the day - clicked the dimmer and the lights came back on fully functional. Damn if it's the switch... i rarely use it!
i just had this problem in a 2003 9c1 in service cop car, there was no lights in the dash or really dim, i swapped out the switch and everything is perfect now. i see these switches tend to go out quick
Well... on my way home i clicked the switch so i could kinda see my speed and left it on for a good 10-15min. When I turned it "off" the car lit up like a space ship (or so it appeared so after being in the dark for 30min) - and they haven't gone off yet.
I had this problem and I took out the dimmer switch, cleaned up the metal a bit, and now my brightness is back. Take it out and clean it up to see what happens.
I'll check HQ but does this entail removing the dash?
Well this gremlin did hit me, and I came to the site to look around for advice.
Now my 0.2 cents. I did carefully take the switch apart, cleaned up all the contact surface, reapplied some dielectric grease, reassembled ,installed, and it is working fine. If it does happen to you, it is worth you while to take it apart and have a look. And to save some $ Thanks to all that posted.
Ps Connect a jumper wire between the Gray and Brown/white stripe wire and it will tell you right away if it is a switch problem. (Dash will light up)

I've had this issue twice with my 2001 since I've owned it. Bought it new in 2001. Both times, it's caused by the headlamp switch in the dash. Both times, the connector to the switch also burned up. Definitely check the connector too!!
Now in my case, it could be due to the DRL bypass, the automatic headlamp bypass, or the quad headlamp rewire. Can't be for sure though. LOL
