    1994 GMC Suburban. Found out today I have no brake lights. Running/parking light, signals, and 4ways all work fine. Checked and replaced the fuse that said BRAKE, and checked and replaced the fuse that said STOP, still no brake lights, so I bought a new brake light switch and installed that, and still no brake lights, went back out bought and installed all new light bulbs.....Guess what??? Still no brake lights. Checked wiring and grounds, checked for corrosion still nothing. Yes the third brake light works, so now I'm stumped.:dizzy:

    Anyone out there that might be able to shed some light on my problem.
    Thanks
    Brian

    Mine was the multifunction switch - turn, wipers, cruise.

    Not cheap, not fun to replace.

    I was thinking the multifunction switch as well. That happened to my dad's truck. Do you have a trailer wiring plug? Are you getting power to that? Getting any power from the stop wires behind the taillight itself?

    JUST replaced the multifunction switch on the 96' yesterday. Same symptoms, $157.66 from the dealer. Takes 30min

    Guess I got gouged. Paid close to $300 for a unit from Napa.....

    Shop charged me an hour I think.

    If you have cruise, then it's $70-80 more. Napa was about the same price with my discount but my cousin is a service mgr at a GMC dealer, so for the same price I figured I'd go OEM:D

    Yeah, I have cruise. And of course I paid "retail". Wonder why I'm doing all my own work now?

    never had a chance to look on a 94 truck but most other gm's have under hood fuses. its worth the twenty sec it takes to pop the hood and check

    My 95 has an underhood fuse panel. I don't remember if my 89 did, but I don't think so. My 81 does not.
