Angry Map lights shorted??

Hello,

I am doing a LED upgrade to the interior lights. I was finally able to get one map done and was working. Then on the second one I broke the bulb, in my rush I just used my pliers to pull from the middle and I saw a spark...

Now neither map light works. The dome is still on, I thought they were on the same fuse?? The fuse that says dome is fine. Not sure if I shorted something out on the board or what...hope not!

Everything else on the overhead console is working. The little LED that turns on when you have your headlights on, all the crawl control settings.

Hoping someone may have some insight.

Thank you!

There are a few threads here covering this and the bad outcomes that result. You might luck out and have it just be a blown fuse. Others have found they shorted out one of the control computers which are not cheap to find and replace.

Always disconnect the battery before doing any type of electrical work to help avoid short circuit damage.

I would start by checking all fuses in both fuse blocks (with battery disconnected) by pulling each fuse and checking with a meter. Check one at a time and replace or re-install before moving to the next one.

Was watching other videos and no one else was...then became complacent...

Curious what control computers would operate along with these lights and if I can expect to run into some other issues later. So far everything else is working...guess I will have to get a meter...

I am not able to find any of these threads that have covered this either.

Well the computers involved will depend on what circuit (if any) was damaged. I would check all fuses first and after making sure all are good and reinstalled correctly; reconnect the battery and see what works and what doesn't.

Toyota labels fuses for the main circuit they control or protect. Sometimes other things are also involved with the same fuse. Without going through all the wiring diagrams, it's easier to know all your fuses are good and then see what works and what doesn't and go from there.

Once all fuses are good, I would put everything back the way it was until everything is working again. I would also check the sockets or bulb clips to see they are not bent or damaged and that bulbs fit correctly. Then start your LED swap over again. I'm guessing you had no lighting issues to begin with.

Getting a meter is a good place to start. Fuses can look good and still be blown. If you need help using a meter, let me know and I'll run through the basics with you.

Related to issue in the future:

When trying to replace the Map Light Bulbs, use a piece of plastic fuel line or clear tygon tubing that fits over the bulb tightly to remove these bulbs. Don't use pliers!
Just a heads up!

I've used tape in the past with success too. Just adding to your list of simple tools that won't risk shoring something out.

In relation to other threads involving issues caused by not disconnecting the battery before doing electrical work - my search (just now) didn't come up with anything. I've searched this issue before and remember at a couple of threads that didn't go well because of short circuits caused by working with power on or battery not being disconnected.

I remember these threads, but don't know why they don't now show up in a search. I did notice that the search function is now "google enhanced" which appears to result in lots of stuff unrelated to what I searched for! Perhaps that's why.

Fuse usually not triggered by map or dome light mishap. My CarTrimHome cheap dome LED melted whole assembly and nearly caught rig on fire but did not blow the fuse. I was lucky to salvage integrated dome light switch because it is directly wired in and has no connector.
