Parking light/brake light gremlins.....

My buddy's 1998 Voyager parking and brake lights stayed on after he shut the van off until they sucked the life right out of the battery. I swapped fuse's, reset the BCM and now they stay on for about 5 minutes, and then turn off. Whats going on?:banghead:

park brake sensor short...maybe not aligned...and of course could be the dash itself. i had problems with mine not coming on and got underneath and played with brake sensor and was fine after that.
