TIPM modules are known to go bad in many different ways, so I'd check that out. Mine was bad and my Jeep would freak out about twice a year, running or not, lights flashing, gauges go dead, horn blares, wipers come on, empties the washer fluid if you don't get it to stop quick enough. A good smack on the TIPM lid would make it quit. Then this spring, my headlights quit working completely. $430 later, I installed a new TIPM and all seems to be fine for the last 3 weeks.
