Troubleshooting Right Turn Stop Signal Not Functioning on a 2000 Ford F350 7-Way

Question:

I am trying to troubleshoot the loss of the right side only blinker and brake lights. Testing the terminals of the 7-pin shows no power but the truck functions properly with no problems. All fuses are fine and all wires show continuity. Im stumped and wondering what to check next?

The problem is somewhere between the 7-way connector and the wiring of your truck. You can try cleaning the pin on the inside of your 7-way. Corrosion or dirt on the pin can cause the circuit not to function. Even if it doesn't look that dirty try using some fine grit sandpaper to get the pin down to bare metal.

Other places to check is the back of the 7-way. There might be corrosion there that needs to be cleaned. Also, check for exposed wire and fix as necessary. Aside from that you would just want to trace the wiring up looking for any obvious things that would cause the circuit to short out and fix as necessary.
