Why is there no lights or highbeams working on a 97 gmc 6500 is there a relay switch and where is it?
The relay will be in "The Black Box" in the engine
compartment.
Generally located on the drivers side. An usally has markings on it
to indicate what is what on the inside. Good Luck and

Eagle talon 1995 brake lights are not working But the lights work when the light are on why dont the brake lights come on?
it could be a plunger relay switch or pressure switch as some people call them. It will be mounted on the brake pedal arm. but i would check the bulbs first because if it is a dual filament bulb it could have gone out on one filament and not another. if your tail lights work and the blinkers work while the tail lights are on then most likely it is the switch on the pedal
1999 Kia Sephia Any ideas on why both tail brake lights do not work although all other lights work including third brake light Bulbs are fine and 30 Amp fuse ok?
If your dashboard lights are also not working, try to switch the 30 amp relay with the air condition 30 amp relay, they are the same type of relay. Plug that in, make sure it is the correct direction. Then try your tail lights. If that doesn't work, use a volt/amp ready on the relay slots themselves to see if you get power to that slot.
Why don't the daylights on a 1991 Cherokee go off when you turn off the ignition?
I have a friend with the same problem. There is a control module that works the highbeams, and running lights. I don't know where it is, or what it's called, but that's likely the problem. The auxillary lights are controlled by a relay. The relay has 3 or 4 wires connected to it. One goes to the high beam side of the headlights. One goes to constant power. One goes to the lights. If there…
Why would the high beams not work on a 1990 Lincoln Town Car with auto headlights and auto dimmer if the dash indicator is lit?
Ok... need a little more info here... but if the high beams work manually, but not with the auto dimmer, my first guess would be that you have a faulty relay somewhere in the system. If the highbeams don't work at all (manually or otherwise) then I would guess the highbeams could be burned out, or you could have a faulty dimmer switch / relay. Good luck! .
On your 1985 Toyota Pickup the tail lights and turn signals work fine and all bulbs check out OK so why don't the brake lights work?
I had a similar experience on my 57 Chevy back in the 60's. 1. CheckFuse Panel fuse under Brake Lights. 2. Check bulbs High Beam filaments. 3. Withrunning lights on tap tail lights to check for wire grounding shorts. 4. Check flasher to see that the lights work. 5. This is what I discovered to be wrong: Look under Brake Pedal for the Brake Relay Switch button. It works in reverse like the button on…
