Electrical problems

[razr69]

I have a Expedition 2002.....not long ago my radio stopped working. I tried to replace the fuse but it blows as soon as I replace it. Soon after this my dashboard lights, AC, gauges, door locks, windows, etc....turn on and off at any given time. My battery light stays on most of the time, but not all the time. I put a new battery in and within 3 months, it was drained again. Seems like something is slowly draining it. I have absolutely no idea what's going on........Any help/ advise would be greatly appreciated.

Thanks
Razr

Do you notice the problems being worse after you drive through a car wash or after it has rained? If so, you are suffering from a failing GEM module that is being flooded out. This is because of a leak in the seal of the windshield.

If this isn't the case, let me know. How are you with a multimeter?
