Question about GMC Envoy XL

1 Answer

No brake lights. Regular lights, turn signals, bulbs OK. Replaced the fuse in underhood fusebox. Still not working. I think it may be the brake light switch. Is that something I can do myself. Is it just up by the arm of the brake pedal? The part looks like a plug in type with prongs. I'm going to go have a look under by the brake pedal now. Thanks.

You did say that the middle or third brake light was coming on though right??? If so you probably have a good switch. I would start by checking the wires coming off the switch on the brake pedal. Push the pedal and use a current tester and see if there is anything coming from the switch when you push the pedal

My left brake light/turn signal isn't working! I replaced the bulbs and turn signal flasher! Still not working! Its 2000 Chevy s10 blazer


If the other brake and turn lights are working the brake light and flasher units are ok . With a test light check at the bulb holder terminal and bulb holder body, test light should glow ,if not check from terminal to a metal part of panel away from the light body . If test light now glows the brake light body has a bad earth if the test still not glowing the power cable to the light is broken.

95 mustange gt brake light dont work check #9 fuses change all bulbs replaced switch on brake pedal hazards lights works ,parking or running lights works,turning signal lights works,what other places i...


I assume the fuse has power if the hazards work.
The third brake light skips the turn signal switch, the regular brake light circuit goes thru the turn signal switch.
Do you have power going into the turn signal switch on the red lite green wire from the brake switch ?

Have a 1999 Chev. Suburban. Problem is with brake lights. Top panel (on roof) works but neither side panel works. Replaced circut boards in tail lights, new bulbs, and all fuses are good. What next?


WITH A GOOD FUSE TESTER, TEST ALL THE FUSES FUSEBOX UNDER THE HOOD & INSIDE THE VEHICLE. IF THE FUSES ARE ALL GOOD WITH THE TESTER YOU MUST HAVE A BAD BRAKE LIGHT SWITCH OR A BAD TURN SIGNAL SWITCH. THE BRAKE LIGHT CIRCUIT GOES UP THROUGH THE TURN SIGNAL SWITCH & THEN TO THE BRAKE LIGHTS. FIRST OF ALL IS THE BRAKE LIGHT SWITCH GOOD ? THE ORANGE WIRE FEEDS THE BRAKE LIGHT SWITCH, THE WHITE WIRE PUTS POWER TO THE TURN SIGNAL SWITCH, SO THE LIGHTS CAN BE USED AS TURN LIGHTS OR BRAKE LIGHTS. , PUT A TESTER IN THE WHITE WIRE & PRESS ON THE BRAKE PEDAL. IF THE TEST LIGHT LIGHTS UP, BRAKE LIGHT SWITCH IS GOOD, BY THE WAY THE BRAKE LIGHT FUSE MAY BE LABELED" STOP", THE FUSE LABELED" BRAKE" IS FOR THE ABS SYSTEM. TO CHECK THE TURN SIGNAL SWITCH FOR BRAKE LIGHTS, REMOVE THE PLASTIC COVER FROM UNDER THE STEERING WHEEL, PRESS ON THE BRAKE PEDAL, PUT THE TESTER IN THE SMALL YELLOW WIRE, THEN THE SMALL GREEN WIRE. IF THERE IS NO POWER IN EITHER WIRE, THE TURN SIGNAL SWITCH IS BAD.

Fuse diagram for a 1990 toyota camry no brake lights but have running and turn , replaced bulbs ,brake switch not sure what else


reconize that the turn signals are involed in this circuirt and do they work is they should? The brake light switchs wire rith at the plug fails too the turn signal switch fails sometimes but not often. Does the thrid high mount brake light work? Make sure the bulbs in it are good to as they fail quicker the the regular lights. If the high mont works and the regular lights don't the turn signal switch or it's connections are likly to be it.

Turn signals


I'd say its either the flasher that needs replaced, or it could be a turn signal fuse in your fusebox, check in your fusebox to see if theres a turn signal fuse, my cars all have one, and ive had to replace them sometimes
hope this helps
