I have a 1995 Mercury Sable, 3.0 liter V6.(130k miles)
For the past 7-8 months, my dome light will not turn off unless the fuse is taken out- which wouldn't be such a big deal if the doorlocks and clock weren't on the same circuit.
They supposedly checked the wiring and said there are no loose connections.
Somewhere else on the net I had seen mention of a 'GEM Module' for other vehicles causing similar problems, but as far as I can see, by looking in the catalogs for Advance Auto, AutoZone, etc. There is no such device in my car.
Any ideas on what to try, or perhaps you have encountered this sort of issue before?
