Dome light circuit - Toyota 4Runner Forum

Keppers12 · 04-15-2023, 04:12 PM

After swapping out door lights and they're respected housing units from doors that work, I deduced that the the dome light circuit to my driver's passenger side seems to be sending a lower signal to that area.

I was hoping someone would know why just this door on the dome light circuit would be effected. All the other doors have a nice bright light and the puddle lights I added are nice and bright. The rear driver's side has a very weak signal. Seems very odd and I assumed the entire circuit was connected!

Thanks in advance,

Have you tried swapping one of the working LED’s with the bad one too see if it’s just a bad bulb? Or touch the circuit like the Map Light mod?

I’ve always had tough luck with buying interior LED kits, one of them is generally dead out of the box.

I e switch bulbs with a dodge t one as well as the door light housing. I’d tapped into all of them for puddle lights awhile ago and the only thing I can think of is that maybe I puked some wires out of the plastic plug when I took the panel offf or I didn’t expose all of the wires when I stripped it🤷*♂️

This is really baffling me. I ruled out its not the bulb or the housing unit for the door light. All the wires tie into the circuit for the map lights, both dome lights and the door dome lights. It doesn't make sense to me that one one door would have a "weaker" signal!!
