I have a 2002 PT Cruiser, purchased new..always kept up with maintenance...just turned to 100,000 miles. .All has been fine till this year when the car runs fine, but ALL accessories stop working: no windows, air, radio, wipers, signals, lights...Dashboard is dead except for the Airbag light. When you exit the car, the alarm goes on as if you left your lights on...However, the battery never dies. Battery, and alternator checked out fine./Brought to car repair in Naugatuck, they did temp solution for a wire. that worked for 1 day. Car returned there, they worked on replacing the harness. This worked till I stopped for gas on the way home. Same problems....too dangerous to drive back to repair shop...any ideas?
