HELP!! Possesed Jeep!!

Ok here's the deal. While waiting in the driveway for the new axle, My jeep's battery got low.... i triyed to start it and gave up, figuring i'd charge it this weekend.....

So I started working on some fender trimming, All of the sudden the Heater Fan comes on!?! (the keys are in my pocket at this time)

I tried everything, Finally i just disco'd the battery.....

Bad ignition switch? Is the fan switch on when this happens or is the switch off? I would think the ignition switch is shorting out and letting power go thru.

I hate electrical crap!

Are you sure you didn't cut though some wire(s) while trimming?

Didn't matter what position the heater is on..........

And.... i don't think there are any wires in the front fender...
