What is the problem with the 2002 Grand Marquis LS?

Asked by Jul 31, 2017 at 08:45 PM about the 2002 Mercury Grand Marquis LS Ultimate

Question type: Maintenance & Repair

A few months ago, my heater/ac fan quit working except on high speed. Recently, I drove the vehicle home from work and the fan was still working for ac on high speed. Parked the car. Packed for a trip. Started the car. No fan for ac, no signal lights, and the abs brake light stays on. what is the issue with this? Module, relay?

1 Answer


One issue sounds like the blower resistor and for the ABS you need to have it scanned for codes. Probably a wheel sensor. Easy fix. Signal lights could be a fuse or relay. Crazy how all this happened all at once.
