CHMSL problem - HELP

96dggm · 03-06-2004, 10:35 PM

The center high mounted stop light (the brake light mounted at the top of the tahoe) in my 99 tahoe has stopped working. I checked the fuses that I thought would be involved, but found nothing.

Anyone know how to diagnose this problem, or how to remove the part and test the light itself?

Any help would be appreciated.

My 95 Tahoe has a similar issue. Only the right two thirds of the LEDs light up. I've priced it out at the dealer and it's approximately $250. Any ideas, aside from buying a new one from the dealer, would be greatly appreciated.

chances are that the thin copper on it have corroded and created an open circuit

If I were you guys, I wouldn't worry about it. I've never heard of someone being pulled over for their CHMSL being out. If you have to have a working one, check your local wrecking yards. GM uses some parts on many different models so you may luck out going to a self service yard and finding one that'll work.

I had a problem with the CHMSL on my Sebring Convertible. Here's a link to what I did:
