I have a 2003 S10. My rear turn signals work, emergency flashers work, and my 3rd brake light works, but my tail light brake lights don't work. What do I do?


Check for power and ground to the lamps. Most likely you have lost ground, since you replaced everything else.

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.

1998 taurus - turn signals were working - pushed the hazard lights button - hazards did not work and also now turn signals do not work


Check the fuse/relay panel for a blown fuse/relay. Also look at the turn signal flasher and the four way flasher located in fuse/relay panel for problem. If the fuses are good replace the flashers to correct the problem. Hope this will help you.

Have four way flashers in front of car but no turn signals on front or rear of car but yet i still have parking lights and brake lights and have replaced the bulbs and the fuses are not bad and the flasher...


The most common cause of your problem is the Flasher Unit. Functioning four way flashers doesn't mean the existing unit is working. Also, there are multiple flasher units on some cars. Since the bulbs are all working, replacing the flasher unit makes the most sense.

Rear turn signals and brake lights out. Front signals and rear tail lights work fine.


the brake lights and the rear turn signals should be the same bulb check the bulbs to make sure they are not blown does your third brake light work if all brake light are out and the bulbs are good check the brake light switch on the brake pedal

No parking front or rear, side markers, brake or dash lights.


Sounds like an earth / ground wiring problem at the rear lighting units, when the flashers are on and you press the brake pedal the power is back earthing through the flashers. Check all earth/ground points at the rear lights.....Good luck hope this helps

1991 Ford E150 turn signals do not work,emergancy flashers flash constantlly unless the flasher relay is unplugged from fuse block


Hi,

If I understand you right based on your post/description, the signal lights would still turn on even if any or both of the flasher relays are removed. Should this be the case, then the signal lights are not getting the power from the flasher relays but from the brake light circuit.

Perhaps your concern is not with any of the flasher, but simply missing or loose ground more particularly with the rear lights. Perhaps you could try determining which of the wires for the brake lights and signal lights (as they come out of the light assembly) would be ground . A test and even possibly a temporary workaround is to hard wire a second ground connection from the determined ground wire of the lights and attach it to any conveniently located bolt or screw to the body. it may be to your advantage to do this on all the rear lights assembly.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
