Re: Pass. Side Frt Parking Lamp issue on 70
Success! Well, success insofar as I found out what the problem is.
This test worked. It is a bad ground.
Now...what is the permanent fix?
Sounds like it might have a bad ground and there is an easy way to check that.
Using a fairly long piece of small gauge flexible wire, strip a couple of inches from one end and wrap/twist it around the bulb base near the glass. Install the bulb and hold the other end of the wire onto a known good ground.
