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 had the same problem on my 1991 GS. The wire to the brakelight switch had come loose at the pedal. Gently tug on the wires going into the brakelight switch on the pedal and see if one just falls out. Mine did and after reconnecting, I had brakelights again.

What you need to do is where your brake pedal is follow the flat piece up into the dash about 4 or five inches now depress the pedal look where the gap is when you pushed the peddle down to when it was up you will see a brake switch mounted sideways how it works when you press down the flat skinny part of the upper pedal goes down releasing the button out when you let it back up it closes the button back up to kill the power

I have a 1991 Mercury Grand Marquis with no brake lights.have checked all fuses still no lights


i`m guessing that the signal lights work,there fore the brake light switch is probably the problem.it is located at the base of the brake pedal and pushes the switch when the pedal is moved.there is two wires for the brake lights on the switch one wire has power all the time the other wire only has power on it when the pedal is pushed.check with a test light for power to these wires at the proper time.also check and make sure the wires are not broken as this is also a problem with this system.
