It sounds like there may be a ground off somewhere, where is the question. Have you used a test light(screwdriver type) at the sockets to see if it blinks for blinkers and lights for brakes. I wonder if you hooked up a trailer if the lights on the trailer would work.hmmm.. just a thought. I am assuming that you tested all the fuses under the hood also with a tester, as I know when I lost my taillights and turn signals in the back it was under the hood marked as GS whatever that meant. I am babbling so I will *******. I Hoped this helps Tim

1987. Why is there no power at the turn signal cam?


Do you have brake and parkng lights? The turnsignal switch on the column is just designed to relay a path to the flasher and then it is designed to interupt the brake and some of the parking lights lights, which cause the flashing on and off. Double check fuses double check bulb socks and bulbs for good contacts. Does the 4 ways work? If the lights all flash then locate the turn signal flasher and switch with emergency flasher if possible to rule out relay. If those are all good and the emergency flasher lights work and bulbs, then you would have a problem with the turn signal switch. Hope this all helps

1995 GMC Jimmy brake lights not working


Brake lights run through the hazzard switch. There are known problems with this, and the multifunction switch. You may need to buy a new hazzard switch and OR the multifunction switch. Before you do that, check the pigtail that goes into the brake switch up by the fender, make sure it's not shorting out up there. Happened to me!

Turn signals, hazard flashers, and brake lights not working on 1996 crown vic. pushed in fuse and worked for minute until hood was shut then went out again. Also took in circuit breaker and had checked....


well makes no sense turnsignals are on ignition switch fed fuse and brake lights are on 24 hour fuse.. to me sounds like bad turn switch... it handles turn signals also hazzards. and brake lights have to go through the turn switch also... it is common problem.. combination switch is what they call it.. not hard to replace either....let me know

Rear turn signals and brake lights won't work


Probably the turn signal switch assembly. This is a common problem with the older Fords. The switch is a self contained unit at a cost of about $100.00.
