Tail light problems

[opie]

Hoping I can get some help here. The tail lights on my 94 Suburban went out on me. So I take the right rear out and looks like it is burnt out. So I decide I will just change them both. Well I put new bulbs in and still not working. Any sugestions? Thanks in advance.

check and make sure you got a brake signal to the brake lights. if no signal you may have a brake light switch bad.
un plug the board from the rear and check with a test light with some pushing the brakes. have also seen the boards go bad too. hope this helps.

Thanks for the reply.

Found the problem. Many years ago I put in an after market harness for towing trailers. The plug developed some sort of problem which caused only the tail light not to work. Took the thing off and they work...
