Interior Lights Not Working 06 H3

[RKTonyC]

Okay, I upgraded my interior lights, the overhead lighting, cargo lighting, and front floor lighting over to led bulbs. All worked great after. I decided to upgrade the vanity lighting in the sun visors as well. Did the driver’s side, all good. Started to do the passenger side, and my interior lights, both overheads, and floor light all went out. The vanity lights are dim as heck. I tried looking for a fuse for the interior lighting but do not see it on the fuse listing, but checked and every fuse is good. I even disconnected the battery terminals to reset the pcm. Nothing, except dim vanity light. Overhead override is off.

Crazy thing, in checking all the instruments, and everything, the turn signals are affected by what ever happened. They flash fast, and only the back illuminate. Hazards as well. AND, when I turn my blower up to 4, the radio shuts off. Still blowing and cold air coming out, just the radio turns off. Which with the model is weird, as as long as the key is in the on/running position, it illuminates no matter what. But now completely turns off when I put the blower to high.

Everyone worked great after I changed the overhead lights, rear cargo lights, front floor lights, and drivers side vanity lights. The issue happened installing the passenger side vanity lights.

Any ideas?

Have you removed the vanity bulb you installed? Just because a bulb is new does not mean it's good.

In an attempt to figure this out, tonight I removed every led bulb I installed. I tested every one of them and they are all working. They definitely are directional in the current flow.

So with all bulbs removed, the issues still remain.

Side note, it seems both vanity lights complete the current flow in each visor from what I’ve found.

Keep vanity light bulbs old school. Your running into led problems. Circuit is not designed for such

I know…now. Should have quit when I was ahead. Everything was fine up until that point.

I have had LEDs in all the interior locations for years with no issue, might replace the vanity with different bulbs. The FV on the LED may be causing issues.

I attached the only specifications on the vanity bulbs.

Received my scanner today. Received some interesting results:

I think you can start with that short and I bet everything else cleans up after that.

It’s at least something to check out next. Being electrically challenged this helps.

Update: So today I decided to replace my plugs, coils and clean the throttle body. I had a misfire on cylinder 1, which always cleared up after driving awhile. But since it has almost 155k, figured it was due. Runs awesome now.

So, I decided to take out the BCM and give it a little internal cleaning, and decided to just replace fuse #56 with a new one. Lo and behold, interior lights, and turn signals are all working perfectly again.

It was a good day!

Thanks for the update, glad it went well. Are you gonna go celebrate with some Kelly's Roast Beef?

 

[RKTonyC]

Yes! I’m buying!

The LED lighting is so much better than the factory stuff

Actually I converted to led interior lighting a few years back and then went back to incandescent lol. Just too much hassle . Led kept glitching. They were prone to burning out and vibration would shake stuff free. Winter time they would freeze or not be as bright. I've now converted all interior lights to soft glow white incandescent for doors / switches for windows etc.
0 to -16 degrees does funny thing to an H3.

I've never had an issue with any of the https://www.sylvania-automotive.com/ light bulbs. I believe quality to be the issue.
