2002 FORD EXPLORER DOOR LOCKS/INTERIOR LIGHTS/AUTO LAMPS/RE

Electrical problem
2002 Ford Explorer V8 Four Wheel Drive Automatic 95000 miles

My 2002 Explorer just went off the deep end one day, with doors locking and unlocking on their own, the auto lamps, interior lights and accessory delay do not work correctly. It's like the car doesn't see the doors ajar. (The door ajar light doesn't come on when the doors' are open.)

The mysterious unlocking / locking stopped after the battery went dead because I left the lights on. (Still accustomed to auto lamps) Anyway, they work fine, except the rear hatch won't open at all.

There is a static-type sound coming from behind the C-pillar panel. I was told that there is a control module back there and that it controls the items I'm having problems with.

I really would like to have a second opinion on this or perhaps some trouble-shooting tips before I make an investment.

If this is the problem, I also need to know if this can be a DIY repair or is there some programming involved from the dealer?

Some other background info includes:
Aftermarket stereo, Viper alarm w/remote. The factory is supposed to be disabled.

Everything worked fine until about a week after the stereo went in. (Pioneer CD/Navigation)

Any help will be greatly appreciated.

These trucks have whats called a g.E.M. Module that are common for failing. You need a real scan tool to check codes and data from it(the code readers wont work). You should really have it looked at before replacing it. But it sounds like its bad. Hope this helps

Thanks for your input.

Is this something that has to be done at the dealer?
(The scan) And if it is the GEM, can I install it myself?

This is something they will do for you because they will probably pull it down to inspect it and or smell it to see if it is burned up inside.
