hey guys on my pickup the turn signals work fine front back left right until i turn the headlights on and the right side still works right but the left rear turn signal wont work the front works fine but the back all that works is the tail light. it has a utility box on it so there is just a single 4" round light on either side. any help is apreciated

 

Check your grounds.

 

Well buddy the only way you can figure stuff like this out is to take that handy dandy Fluke Meter and start probing around. Sounds to me like you are getting a short to ground somewhere. Check all the wiring for your headlights and see if they are coming in contact with any wires for your signal. Also check the wiring harness in the steering column for the turn signal switch. Best of luck to ya bud.

 

My rear brake/tail/back up light sockets were all crusty.

 

thanks guys ill check it out. chances are ill get pissed and rewire the whole pickup i hate old wiring it drives me crazy!!! these pickups have a few more things to wire than my 76 chevy k20 that i rewired last summer but im always up for a challenge
