Question about 2001 Chevrolet Silverado 1500
Brake lights not working on the box, everything else works. Bulbs are good, third brake light on cab works.
Note: a week ago gas tank was R & R to replace sending unit.
I figured out my problem!
From the VERY BEGINING... I changed my brake pedal switch with a BRAND NEW switch, and the lights still didn't work.
Well, I went back down there with a live wire and touched the contacts..and guess what.. the brake lights lit up!
I got a faulty NEW brake pedal switch!! I went a year with this problem, so learn from my issue, test even your new parts if it doesn't fix the problem to completely rule it out!
I hope you guys figure out what's going on with your issue.

There is a probable bad wiring connection in problem one and three.
#2 Possible water leak causing bulb break. Try wd40 in socket. you need a wiring diagam and cheap voltmeter if you want do it yourself.

I had a similar problem with my 1994 S-10 LS extended cab. Both tail brake lights worked fine. I removed the 3rd brake light cover and tested for voltage at the steel center of the two rivets and found the positive (driver side) negative (passenger side) were good. I checked the two metal strips that send power to bulbs and found the positive side was open. Seems the flared side of the rivet was not making contact with the metal strip. I bucked the rivet with a punch and hammer and it took care of the problem.
