brake lights are out

Asked by Sep 01, 2015 at 08:18 AM about the 1997 GMC Sierra 1500 C1500 SL Extended Cab LB

Question type: Maintenance & Repair

I have done  a lot of research into this issue, both online and in auto parts
stores, has left me frustrated. First off, I own a 1997 GMC Sierra 5.7L V8.
What I am having trouble with is that my brake lights do not come on, all
three. After a few minor checks (bulbs, etc), I could not resolve the issue so
I performed a ground up inspection of the electrical system.

Bulbs are intact.
Grounds are good.
Fuses, both the 10A and 30A, are good.
I replaced brake light switch. Still nothing. When I move the switch off the
push rod and shove it up towards the top, It works fine. Trouble is it wont
stay put while I'm driving

I think you found your problem, if you can get them to work at the break light switch, something is wrong right there. There is a break light relay in one of the fuse panels, probably the one under hood, but this does not sound like that.
