third brake light and the rear defogger
i have a 1986 iroc. The third brake light comes on with my rear defogger when i touch the brake. The 3rd light and the defroster stay on when brake is released. To turn off light i must turn off the defrost switch. Everything used to work right until my defroster quit about three months ago. The ony thing done in that 3 month span was today. I noticed my 3rd light was out and checked the bulbs. They were all good. When I put it together, the brake light works as mentioned above instead of releasing the brake and the light going out. HELP?????????

Sounds like it could be a bad ground connection. Check the connectors on each end of the hatch lift strut on the passenger side.

That is truly bizarre! The defroster wires are the ones that go through the hatch stuts but the 3rd brakelight, at least on my Camaro, are controlled through the contact switches on the rear hatch opening trim. I can't imagine how the 2 could get crossed!

On the 86 at least, with the 'humpback' third brake light, both that light and the defroster share the same ground connection through the passenger side strut.
