So on my 87 iroc, I cant seem to figure out what is wrong with my third break light. At first I thought it might just be some dead bulbs, but then I replaced all of the dead ones and to no avail it still doesnt work.
I figure it is probably the wiring, but I think it might just be the connector.

Anyone else have this problem?
