I bought my car with aftermarket LED-s in only the front and the rear dome lights. I changed them back to normal W5W bulbs. The rear dome works, but the front just flashed once, and after then no response. I’ve checked the bulbs, all the fuses. Every function and switches and other lights are working perfectly on the front dome. So I disassembled and reassembled the dome, I found nothing.
Please help, where is the problem?

Did you try the old bulbs in it? Do you have a multi-tester to check if power is actually getting to the socket? Are the contacts for the bulb damaged? Is it possible you pulled the connector/wire off inside?
One way or another you will be able to figure it out, you just need to dig more

Dannytech

I’ve already tried all of the things you said There is no any voltage at the sockets. The connectors and cables are good. And as I mentioned, few days ago I disassembled the whole unit in pieces, and didn’t find anything unusual. The problem has to be somewhere else. Maybe can bus?

Sorry if this is a dumb question, but is the dome light switch set to off, on when doors open, or always on?

Dannytech

It doesn’t matter where do I set the switch. Still not working :/

Can you trace the wire back very far? I had my dome off maybe a year ago for a different reason, but I think I recall a shell hiding all the buttons and what not. Normally I take stuff like that apart out of curiously, but I didn't and can't remember why. Probably because it was glued or something and I'd have to break it? So I was wondering if you took that apart to see the switches n stuff and trace the wire.
You should post pix too, so we can better help and for the next guy that has to root around in there.

Did you check the bulb holders? The metal pieces inside the holder maybe damaged.

I damaged mine when I forced the led bulbs to the holders but the replacement bulb holders were not expensive from the stealership.

Dannytech

The bulb holders are perfect. And if I took out the holders, there’s still no voltage on the PCB.

I did’t really catch what you’re saying. You mean some of my wires are broken?
Yes, I will post some photos soon.
