Dome light/Electrical Question...

[NicD]

Already did a search - Simple electrical problem...

I've been visiting here for years and have been able to find answers and opinions to practically every question via searches, but couldn't find this one...

Car: 1990 GT

Problem: Dome light wont turn off and drains the battery...

Solution: Check the most likely culprits - dimmer switches and pin switches in the door jams...

Question: Until i have a chance to find the problem, can anyone tell me what fuse number powers the dome light, and if it powers anything else more important? I'd like to pull the fuse for the time being to spare the battery, but i can't find my owner's manual and can't find the info in my Hayne's book...

Any help would be greatly appreciated...

Thanks...

Love to help ya, but the fuses in my '88 are not tha same as in your 90

It's fuse 8 in both an '88 and '93, but you'll lose your other courtesy lamps, radio, power mirrors, dimmer switch, and fuel filler door release. It would be more convenient to just pull the offending light bulb.

The dimmer switch will turn the dome light on with the doors closed. Remove it & inspect the switch & wiring.

Can anyone confirm or deny for me that fuse 8 will kill the dome light in my '90? Or that simply pullling the bulb will do the trick?

Anyone with a '90 got their owner's manual handy?

here is a diagram of a nice box!

Pulling the bulb is good too, but I had an old crown vic with a bad trunk bulb and it drained the battery too! That was an expensive fix!
