right tail-light issues: sometimes works and sometimes not?

Question

My son's '93 Neon' right tail light works on and off. The left one has no problem. He has changed the fuse, checked the light itself. He was told it is probably electrical. Any suggestions on how and where to start checking? It seems obvious its something directly attached to that rear light. Signal and backup works on and off also. I think it's a loose wire, but have no idea where to look. Someone mentioned Dielictic Grease on another tail-light Q. Where is that found and would it affect only one light? Where is the Harness connector found? Thanks in advance.

Answer 1

I would check the ground wires, if that does not help then it may need a diagnostic check

Answer 2

First check the bulb, the filament sometimes will make contact as the car wiggles. Second check the light bulbs connector for rusted or warn contacts. Open the trunk to access the rear lenses.

Answer 3

Did it initiate occurring once you uncle handed on to the great beyond?! it will be that he's attempting to communicate from the grave. perhaps he's attempting to inform you there is something incorrect with the truck that he replaced into making plans to fix before he left. Or it ought to easily be some free wires. carry it right into a mechanic they have voltmeter, and such that they could be able to apply to diagnose those complications. (it truly is electric powered complications, no longer problems with haunted autos)

Answer 4

Yup...ground wire to the body.
