Re: 83 C10 - No turn signals

I had a similar issue with my 77 C10 but mine was the tail lights and dash lights. The fuse blew so I put a new on in it and it blew again. I searched my truck with a fine tooth comb with no luck. Ended up replacing the harness from the firewall to the back of the truck and it fixed the problem. I tore my old harness apart and searched it inch by inch and could nver find the problem with it.
