Dome light Gremlins!

This is really weird...so perhaps ya'll can school me on how the dome light is hooked up.

A few weeks ago I was driving to work at night and after a few times....I finally realized my dome light was coming on by itself but only when I'd make a turn and the truck would 'lean' into the turn. As the truck leaned, the dome light would come on and then go out as the truck flattened out again. The door ajar light on the dash NEVER comes.

So, today at work...I get out and start playing with the buttons on the door. There's a pie shaped button and I still don't know what that does. There's a rubber plunger looking button. At the time.....my drivers side door was open (obviously) and I'm pushing this button in - watching my dome light come on/off as I press it. Also - the 'door ajar' button came on at the same time along with the dome light. I even tried to slowly press & release the plunger to see if the dome light would come on without the dash light. But I couldn't do it.

I get home and start playing with the button again, in/out/on/off...turning the dome light switch door/off/on.... but this time, drivers side door is open (same as before) and I'm pressing the plunger and the dome light is staying on constant. I shut the door.... and hit the lock key, and the dome light stays on. Then...open the door, play some more ... and finally, the thing went out when I locked the door. What the??

Anyone have this weirdness going on? If I can actually narrow it down to what this is or could be, it'd be much easier taking it to the dealer and convincing them there's a problem and having it fixed under warrantee.

Something electrical and not sure if its switch related, ground, or what?

I have an 07 DC PreRunner also with dome light gremlins. Started when the truck was brand new, the light did not always come on when the doors opened. I took it into the dealership who said it was a "loose wire". My light still doesn't come on everytime I open the door, so I plan on taking it back in soon to have it looked at again.

 

there are two grounds and one constant hot on the dome light. one ground is activated when you unlock or open the door the other is just a constant ground for the switch on the light itself. i'd say there is a ground in that line somewhere perhaps some water in the door switch.

 

+1 on a weird ground somewhere. I've got my vote on a nicked wire. Happens all the time, all it takes is one slip of a screw gun and you've got yourself an electrical gremlin.

 

Thanks gang!
I'll do some more investigating next week. I'll only go so far before taking it to the dealer (warrantee). I gotta have an idea of what it is so I can atleast steer them in the right direction...versus the excuses they always give ya "It didn't occur"

Keep the thoughts rolling!!

 

Came back again...similar to this post:

I'll have to check-in with the dealer or something?
