Asked by Guru1DXHH Aug 20, 2019 at 01:25 PM about the Mercury Grand Marquis

Question type: Maintenance & Repair

2003 marquis I replaced the battery and alternator. battery indicator is in the middle. Car starts right up and after driving 30 miles or so something brings the battery down and the car shuts off. front passenger window slow to go up (don't know if that has anything to do with it) Does anyone know what the problem is?

1 Answer


Take the vehicle to you local auto parts store and have the test the battery and charging system, it's free. If everything checks out good, try to find the electrical short that's draining it down. It's not the window unless it's stuck in the either up or down position.
