I need a more experienced hand, in diagnosing a non functioning dome light. The one in the center of the overhead headliner. I have no center dome (overhead) in the headliner. I do have both spotlights on the right and left of the dome. Both spotlights on the front portion of the headliner also work, when you push the on/off button. I've also lost my backup lights,when the truck is running, and you shift to reverse.
When I open the drivers door, & trucks turned off, and poke the dome override button, I do get the lights on the inside of the right and left front door panels, so the dome override seems ok. Turning up the rheostat by the dome overide turns on the door panel lights, but not the overhead dome light.
I had a set of running boards installed,with Westin lights, that they tapped the electrical above the drivers left foot. I've traced it, it all seems clean, no frayed wires, etc.
I've replaced both the backup light fuse, and trailer backup light fuse, in the fuse block on the left fender apron. Nothing changed. I also pulled the fuse on the left fender apron fuseblock for INTPARK for interior lamps per my owners manual. Ironically, all the interior lights still work except the dome with the fuse pulled.
I replaced the overhead dome light, which was a large tube style lamp with a label on the metal ends of TS 578. It wasn't blown, but I replaced it with 211-2 style bulb which matches the size, but the ends are a little different. The oem dome has 2 wires stuck in the sides of the metal band, like somebody shot a tiny staple into it, and only the top of the staple head sticks out to make contact with the connections.
I believe what I need to look for and don't know where to find it, is the "delay" switch or fuse. That is, when you hit lock on your clicker, the doors lock, and as I recall, the dome light comes on, the two front spotlights come on in the headliner, and the backup lights go on for about 20 seconds then it would slowly fade to black. It's the same when you click unlock, that relay lights up the dome lights, front headliner spotlights, and backups, as least I think it did.
Can somebody help me identify that relay, and where to find it? If there is a way of testing it with a voltmeter, any advise would be appreciated.
