I think your solution is right on.  After further investigating my problem, I found that after pressing the hazard flasher switch several times, sometimes my turn signals would work sometimes they would not.  I fixed my problem by replacing the multifunction (HF, TS, wiper) switch, but I think your solution might have worked and saved me dollars.

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.

Light switch gone bad?


The light switch controls the tail lights. Look for a fuse for them first.

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!

1989 chevy 1/2 ton.brake lights or emergency flashers dont work.tail lights an blinkers work.


The Blinkers and the Brake Lights are the same bulb. So check the brake light switch. Flashers use a different flasher unit, than the turn signals

Hi I have a 1989 F150 and none of the brake lights work. I checked the fuse, the brake peddle switch. Oh and the emergency flashers only work in the front.


SOUND LIKE TURN SIGNAL SWITCH COULD BE BAD.SOME CARS BRAKE LIGHT CIRCUIT SHARES THE REAR PORTION OF THE TURN SIGNAL CIRCUIT.

Brake lights only show on center 3rd high stop tail lamp


Yes, the flasher does interrupt the brake signal. you do know that this is a push on, push off switch. Some try to pull this switch to turn off flashers, but, it has to be pushed again to turn off.

No brake lights of blinkers 1990 dodge dynasty


While not likely, it is possible that the light bulbs in both sides are have bad filaments. Turn on ignition key (but don't start engine). Then turn on parking lamps (first detent or "click" on headlamp switch). Walk around car and look for illumination on front parking lamps and rear tail lights. Turn on the right turn signal. Are those (right hand) lamps now changing brilliance? Try the left turn signal in the same manner. Are those (left hand) front and rear lights changing briiliance? Take note of any positions that did NOT change briliance when the turn signals were activated. If NONE changed briliance, you either have a bunch of bad bulbs (unlikely) or a bad flasher (more likely) or a bad turn signal switch (most likely) or perhaps wiring problems (possible if the car has been in a collision or has been "worked on" by some "non-expert" mechanic). Check the action of the emergency flasher control switch located on the steering column (facing up). Pushing it in (down) should result in the button going to two different heights alternately (low, high, low, high). You could just have bad flashers or corroded flasher contacts! Good luck!
