94 Courtesy Fuse keeps blowing

This one seems a bit strange...
I have a 94 Trans sport 3.8 SE that keeps blowing the Courtsey fuse.

Strange thing is it only happens after driving and putting the van in Park.

Any ideas?

After a little more investigation seems the problem might not be related to placing the van in Park.

I've determined that a very short drive (around the street) does not result in the fuse blowing, also it seems that the fuse blows either when simply stopping or placing the parking brake. I need to run a couple of more tests when I get more fuses to determine if I wait long enough before applying the parking brake if the the fuse still blows.

Fuses blow because too much current is being drawn across it. If nothing additional has been hooked up somewhere using the courtsey wiring, then my money would be on some type of a short. It could be an exposed wire bumping up against some metal, a defective piece of equipment, etc. The fact that you drove around for a short time without issue might give a little more credence to this as the shorter the trip, the less chance the wire would have to bump up against something and short out.

If it is this, good luck in looking around for it. I'm sure the wiring for the courtesy fuse runs all over the vehicle.
