Hey Chris
I think you have a switch that is stuck. I looked in my chiltons manual and in the wiring schematics they show a switch on the handle of the e-brake. I'm not sure what type of e-brake is on your trooper. Mine is on the center console and I'm sure I would have to take the console apart to get to that switch. It could be just dirty or it could have shorted together. Good luck.
