Sounds like it has a bad brake lamp switch. It's possible that if you have a third brake lamp and that works, but the others don't, it is a bad multifunction switch. The brake switch is located on the brake pedal. The multifunction switch incorporates your turn signal/ hazard/ high beam lever mounted on the steering column. As confusing as this sounds, I hope this helps.

Where is the tail light relay located on a 2003 Mercury Grand Marquis GS? My tail lights and parking lights do not work and I have checked all my fuses.

if it was just your brake lights i would say its the brake switch. if you have checked all light fuses next step would be checking the bulbs. if bulbs are good check continuity with a test light.

I need to find the flasher relay for a grand marquis 2001 .does it has one? My turn signals wont work I can hear the sound but don't even flash

Yes, it does have a flasher, although it may be a combined unit with the hazard flashers relay. So you hear the clicking of the flasher relay? That seems to indicate the relay is working properly. Have you checked the bulbs and the turn signal fuse? Any turn signal bulbs light up anywhere, front or back?
How about your brake lights, do they work? Your car may have separate, stand alone turn signals in the rear, but many American cars use the same bulb and same filament on the bulb for the brake lights and turn signals. If your merc is like this and the brake lights work, then the bulb must be good.
Turn on the hazard flashers and see if all bulbs work and flash at each corner of the car. This would be the same bulb as for the turn signals. If they work, it could be a bad turn signal switch, may even be the flasher relay somehow malfunctioning, and in a few cases, a bad hazard switch can affect the turn signal switch. Check fuses and bulbs first. If you have any type of body control module that controls lights and other accessories, you may have to investigate that. I know I'm not being very helpful, just throwing out a few suggestions. Good luck.

I have a 93 4-door grandmarquis.The brake lights dont work and the gear shift is loose,are they tied together? How do i get the brake lights fixed ?I already tried fuses...

You can check the brake light bulbs by removing the covers in the trunk, which may or may not be hidden behind a trunk lining. If there is a lining, simply pull it back and remove the protective cover and pull each bulb out and check for broken bulb wires or black burnt marks on the tips of each bulb.

I have a 1998 Grand Marquis and the brake lights and the turn signals stopped working. I checked the fuses and they look ok. Any suggestions??

I have a 93 4-door grandmarquis and everything works but the brakelights.
I was told that the gear shift is possably tied into this because the gear shift is loose.Is that true?
And what do you suspect is the reason the brake lights dont work?

Turn signals don't flash when braking 99 grand marquis

Check all earth wires on all lights.
most lights in cars run in series so if u loose one you loose the other mainly caused by bad earth on globe holders or corrosion where bulb sits.
little sand paper goes a long way.
