Dome and Map lights not working

Replaced my map and dome lights with meso customs. Worked fine for a couple days and when I turned my truck on this morning they came on for a split second and then shut off. I replaced the fuse and still not working. Any suggestions? TIA

 

Your certain your DOME Fuse (7.5A) is good?

Do they come on if you set the switches to On instead of Door?

 

Yes I went to oreilys and ensured I got the 7.5a (mini) fuse and replaced. It won’t come on with switched on door or on. Maps will not come on either. Starting to think maybe I fried the panel.

 

If by panel you mean the Body ECU or the MESO Light panel?
I don't think this is true as in the ON Position the ground doesn't use the Body ECU.

Swap it back to stock lights and see if they work. Or check the voltage and ground at the plug going to the lights.

 

I meant the overhead panel. I have put the stock bulbs and cover back and still not working.

 

Check the voltage (12 Volts) at the Pink Wire and verify a proper ground at the White with Black Stripe wire.

Do the Vanity Lights on the visors work?

I suspect an issue with the wiring between the fuse and the Lighting where they all split apart.

 

^^^This^^^ Maybe they are of sketchy quality and blew themselves out and took everyone else with them. Find a confirmed-working matching bulb and swap it in. I think they are all either common wedge #194 (3w) or #168 (5w).

See if the original bulbs work somewhere else on the truck (license plate illumination) you'll have your answer. I wouldn't experiment with the LED bulbs in any other socket yet.

Good luck and Welcome to Tacoma World!
