Brake lights I have a 1991 Mercury Grand Marquis with no brake lights. Have checked fuses, used test lights. Still no brake lights, a friend suggested that we trace the brake light wires, but don't know which ones they are. Need a wiring diagram. Can you help or any suggestions???

I am working on a 1998 Mercury Grand Marquis. The brake lights are inoperative and also the emergency flashers. The third brake light works ( one in rear window ). Can't find flashers.

I have a 1995 Grand Marquis and my check engine light came on a few days ago. The car died today while holding the brake in waiting at a red light. I quickly turned off the car and turned it back on and it started right up. It seems when the brake is held in the engine seems to struggle and begin to die, but then kicks back in. No problems when applying the gas. Any solutions?

I have a 1977 Mercury Grand Marquis the turn signals, brake lights, and turning lights do not work. The running lights and hazard lights do work.
