2000 Mustang wiring question

[MinnesotaMike]

My son just purchased the car and noticed that the dome light was
missing. We replaced the bulb and the light stays on all the time now,
even with the car turned off. Since there is an aftermarket stereo
installed, so I assume that there is a wire misconnected. Any thoughts
on this or is there another possibility that I should look at? Any
suggestions appreciated.

To assume the stereo has something to do with it doesn't make sense. That's
#57 on the list of possibilities. Check to see if the dome light switch is
on first, then check out the door switches. Then pull the dome fuse and see
if it goes out. (with the door closed of course). Many many avenues to
explore before blaming the radio. Sounds as if you have a problem with
people putting in aftermarket radios.

If the fuse is pulled, why does the door need to be closed?

Okay, here's what I have. No fuse labeled as Dome light, so I pulled
the "GEM, Interior Lamps" fuse. The dome light works as it should. Now
I know that fuse is important because it wouldn't be in there otherwise.
The question is, where do I go now? And what is GEM (it's list 5
times)? Thanks for the help!

Generic Electronic Module: I stole this text from another website:

The GEM module is responsible for the following: Door Ajar & Low Washer
Fluid warning light, Remote Keyless Entry & Power Door Locks, Power Windows,
Courtesy Lamps, all the Door Ajar Switches, including the Lift Gate,
Interval Wipers/Washer, Heated Mirrors & Rear Window Defrost, Rear Air
Suspension, Warning Chimes and also ties in a bit with the ABS & Air Bag
System. There may have been a couple of other little items I missed.


As for where it is on the mustang, I don't know.

Thanks for the GEM info. Any suggestions on what to look at next for
the dome light?

The GEM provides a delay feature for turning off the light. The GEM
might be messes up or someone might have messed with the wiring for
the light.

I'm not certain about yoru Mustang, but my '95 Bronco turns the dome light
on and off by twisting the light switch.

Pulling the light switch turns the lights on, twisting the light switch
adjusts the brightness of the insturment panel, if you twist the light
switch to Full Bright, it will click and turn the dome light on.
