Dome light switch HOT

[Moosemoon]

I had the cluster replaced on my 2001 YukonXL 2500. When I got back the dome light switch didn’t work. I took it back - they ‘fixed’ the switch. Yes the dimmer works and turns overhead on and off but the switch and surrounding area is HOT to the touch. To the point that I worry about it catching fire. Thoughts?

First things first. Take the cover off and take a look at the bulb and its connection into the holding clips/connector to ensure that it is fully seated.

Thanks - will try that

Well - there doesn’t appear to be a bulb at the switch itself. It is the area right around the dimmer ‘wheel’ that gets hot. Mostly up and to the right. Thanks

There's a backlighting bulb in the switch, accessed from the backside of the switch body.



It looks like this:

Hmm will have to look for that. Not sure I know how to get there but will chk to see if I can find it. Thank you!

Sorry to be dumb but how did you find that on RockAuto?

I'm familiar with the switches and the bulbs since I've re-bulbed mine.

I found the switch on Rock Auto, then there are pictures both on the multi-listing and the same pics when you select the part. I knew from experience where the bulb gets inserted, but I don't think RA has the bulbs available; they're somewhat of a specialty item.



For the bulb I used www.carradiobulbs.com since that's where I had bought the bulbs for my work.

Thank you for your help. I was able to get the ‘hot’ one out. It is an aftermarket POS that doesn’t even have a way to replace a light. The wiring harness has also been changed at some point. I doubt that it is correctly installed. I am quite skeptical that I won’t have more problems with ‘new’ used one I just ordered from ebay. Arghhh
Thank you again! You all have been so good to me!

Thanks for the heads up on where to get a bulb!
