It does sound like a bad bulb


George

 

Well the truck is gone to Oregon on a fishing trip so it will be a couple of weeks before I can do anymore work with it. At least the 4WD is working. Hopefully I can come up with a bulb in the meantime. Still can't understand why the new switch would not light up though since it appeared the bulb is good in that one.

Thanks for all your help!

 

Well I decided to check to see where the leads from the bulb go to on the new Dorman switch I tried. I found both sides of the bulb go to pin H(gray wire) and no ground pin G(black wire). I'd say that is a problem. I bought this after market switch to help me troubleshoot the issue, waste of time and money. I did get a bit of an education though.
