Thanks to those of you who responded. Didn't mean to post and run - it's been a crazy week! I checked every fuse myself, so I know there's no blown fuse. I don't know what to think about this. I guess I'll have someone else look at all the fuses because there's always a chance I missed one.

 

Had the same scenario with lights going out. Turned out to be the 10 amp parking light fuse. Thanks for the post. That would have probably been the last thing I would have thought to check. Have no idea what blew the fuse, and hopefully it won't go again any time soon. DW

 

On my 2006 LT1, I had a very similar problem -- the ENTIRE dash was dead, including the gauges and the stereo, but the car was otherwise working without problem (all external lights worked fine). This happened intermittently two or three, maybe four times. I traced the problem to the dimmer switch on the dash being pushed TOO FAR to the right, a tick beyond the last setting for maximum brightness. Once I brought the switch back in to its normal range of operation, the problem has never occurred again. This was about three or four months ago that I resolved it, so it appears to be a permanent fix for my particular situation.

 

i might have the same problem that brainless has. this is it. i can only notice it at night. i have an 09 hhr with the dimmer switch in high. so my speedo and radio lights are bright, but the lights of the temperature unit under the radio are low as well as my shifter light and the lights on the switches of each door. funny thing, when i turn my dimmer switch off, i get now the opposite. speedo is low with the radio. but the temperature control unit is in like the middle brightness as well as the door lights. anyone have an idea of what it could be? i bought a new dimmer switch and as soon as i disconnected the other one, all the lights came on and bright. but the dimmer switch is not it. put the new one in and still with the problem. any help?!
