I have a problem with a 7 prong factory installed tail light receiver for a trailer plug in. The poles for brake, left and right turn do not work. The other 4 poles do work. I've checked fuses and found a bad one but the rest seem to be OK. Could there be something else like a relay or someting that is bad?

No to the relay. Do the signals and brake lights work on the truck? If so, then no to a fuse.

Have you taken the receiver apart and checked the wiring in?
