The HVAC controls are also dark where they used to light up. Same goes for the back-lights on the dimmer control switch.

Next issue is the compass, not sure if it is related but I believe it is. When driving during the day the compass light is on an works correctly. Once the headlights come on the compass goes off. If I manually turn the headlights off the indicator comes back on. Ive seen other threads around where people have had similar issues but no fixes.

Things I have tried so far:
-Check fuses

Any help is appreciated.

Hi all... I have the exact same problem that ZR2 had.

1999 Blazer 4dr 4X4 - my dash lights and the compass display all won't work with the headlights on. So I figured dimmer switch like suggested here. So I went to Parts Source grabbed a new one and changed it out...voila everything was back to normal... this was about a week ago...

Today I hop in the truck after work and bloody heck the dimmer switch is blown AGAIN within a week of being replaced... I find it pretty odd to blow 2 dimmer switches and having the 2nd blow so quickly... any thoughts anyone?

I can't really imagine a bad ground... the dash lights aren't flashing or pulsing or anything while they work... there is no indication that there is a problem until suddenly all at once they stop working again...

I thought I saw something while searching the web about aftermarket radios and dimmer switches in these things... I do have an aftermarket stereo in the truck, but I'm not sure if anyone has heard any issues with this?

Thanks for any help folks!

andrewhere7 is an unknown quantity at this point

Most of the time on a 2001 the emergency brake is just nearly engaged andshuts off dash lights. This can happen with out brake light on dash being on, so before you change a dimmer switch for this problem try lifting up on the peddle while pulling the break release handle.
