THANKS JOE

 

Did you use a test light and see if power is getting back to the socket? If it isn't then you will need to trace the wiring back and keep checking for power. One place I would check is where the loom connects up underneath the chassis in the rear. It may have become corroded and a simple cleaning might take care of it. Good luck, electrical problems can be a nightmare sometimes. Just be patient and keep checking until you find power.

 

break out the testers. You should be able to pick up a cheapy tester from pep boys or any other store like that. Most of those are a combination voltometer/ammeter/ohmmeter.
