    When you use "earth" do you mean "chasses ground"?

    I got all new bulbs,sprayed electronic cleaner in all of the bulb holders.

    Were I'm having my proublem is,I don't have the right diagram that shows me all I need to know.

    The brake switch plug has 4 wiers ,ornge,white,drak purple/lite purple,brown, I know on the brake switch there are 4 terminals that plug into the brake switch,when the brake is applied the ornge wier touches the wite wier,witch makes the wite wier hot and makes the top center brake light come on.

    The lite purple and the dark purple wiers go together as one,and the brown wier must be ground.

    I know the white wier gose into yellow(hot) and the black is ground,for the top center brake light to come on.

    What is the 2 purple wiers for,and were do thay go? Do thay turn into any colors,like the white and yellow do ?

    Do you have a 95 Blazer wiering diagram that shows the intire back brake circuit from front to back?

Do the non working bulb holders have power at the bulb terminals?If not back track to the one that works.The flow of power or earth is bad and its probably happening between working and non working.Do you have a trailer plug?make sure the joins are secure.Maybe two wires touching?Have you put an earth to one of the bulb holders that dont work.Try taking the working bulb out and see if the others light up,Hard to do or suggest test without vehicle there to work on and makes it hard not knowing exactly what tests youve done but suggested a couple in the hope that theres something that helps.Good luck

I worked at a GM dealer for 5 year's now and when this kind of think happens it's usually a circuit board that the bulbs plug into or if it dont have the circuit board style the ground wire in the bulb socket corrodes and brake's

The wires provided for a radio system are as follows:

Black = ground

Harness Wires provided for the speakers as follows:
Left rear speaker = +brown -yellow

I have a 95 chevy blazer with no brake lights I have replaced fuses, bulbs, brake light switch, and the multifunction switch they still are not working what should I do


Go under the truck and check the wiring harness to the rear lights, they are prone to problems in the harness, probe it from where you get a light on a test light to where you don't, then isolate the break

1998 chevy lumina: rear window brake light not working, left brake light not working, rear left turn signal not working


See if bulbs have burnt out in the left brake light and rear turn signal (one bulb if combined) and also rear center high mount brake light.

If the left turn signal has a slower speed than the right turn signal, this is a symptom of a bulb or bulbs burnt out.

Usually, the wiring is not a problem, but I would not rule wiring (or sockets) as a problem out.

Good luck on this repair.

Do the lights turn on on the dash when you signal left or right?

Do the four way flashers work?

If no to either of these check the turn signal flasher module.

Brake light dont work. 2006 chevy truck, 4.8L 2wd


Some of these had two fuses for brake lights. One for the top/center stop lamp and another for the rear left and right brake lights. Usually one said "stop" and the other said "brake" and one was in the underhood panel while the other was in the dash fuse panel. It's not uncommon to blow a brake light fuse [LR and RR] if you tow a trailer but some of these had seperate fuses for the trailer lights also. If you have a test light check both sides of the two fuses for power [ignition key on] while stepping on the brakes. It should at lest narrow your search a bit.

My brake lights dont work on my 2001 chevy blazer. Bulbs are good and fuzes are good. The center high mounted light above the rear hatch works fine. Just no other brake lights work. Any help?


A very common issue with these is the multfunction/turn signal switch in the steering column.GM has a recall on this problem you should contact your local dealership have your VIN number to see if your vehicle is included in the campaign. If so the repair should be minimal cost or no charge to you at all.

My 97 chevy blazer, the brake lights dont work but the third brake light does and the turn signals or hazard lights dont work??


More likely it is the hazard/turnsignal/highbeam/cruise control switch module. It costs about $275 for the module. However there is a repair kit for the likely culprit...the hazard button. Try jiggling it around a little, see if that helps. Spray a little WD-40 into it so it can jostle back into it's correct position. You could try a junkyard unit or Ebay. It's not too hard to change. The hard part is doing it without removing the steering wheel. It can be done. I've done it. But hopefully you can locate the repair kit which costs about 15 dollars. Good luck.

99 Chevy Tahoe... Rear turn signals, brake lights, and hazards


I had this problem, and to be honest, it happened to the left side about a week later...it's the board that the bulbs plug into...it's a very common problem with this model. So popular that you can normally get the socket board off the shelf at a parts store! it's extremely simple to replace, and I replaced all the bulbs at the same time!

Brake lights do not work, all other lights work.


My fiancee' followed Ron's instruction, on where to find the brake light switch, and was finally able to locate it, get it out, and replace it with a new one. I now have brake lights. He had been looking all morning for the switch but could not find it, and he is an ace mechanic, so thanks to Ron for his expert advice. You guys are the greatest!!
