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.

2005 Suburban brake signal light issue


Sounds like a faulty turn signal switch. The brake light wire is routed through the turn switch, so it appears the turn switch has gone crazy.

1991 Nissan Pathfinder left turn signal comes on when I apply the brake


check that all your bulbs are correct and are making contact. this commonly happens when a wrong bulb is installed in a socket. the other reason this happens is a bad ground, and one bulb uses another as a ground path. I would start at the rear left light and check that everything is good there, then move on to the front. 99 percent of these kinds of problems are at the lights themselves.

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.
