I have a 92 4door. My brake lights are not woring. At first I thought it was a fuse, checked, but it was fine. Pulled the bulbs out, the high voltage filaments were all burned. So I changed the brake switch, worked for about an hour then went out again. Bulbs are fine, fuse is fine. I don't know where they are grounded so I can't check it yet. Any help would be great.

 

If you have a test light have you checked for power at the bulbs?
The manual says the ground in on top the rear shelf in the middle. That seems a little odd so i'm going to do a little more checking on that.

 

Anyone know where the ground is? I need this car in the morning.

 

once more for the ground?

 

that happened to my 92 eg hb not too long ago. i had to get new wiring for my rear brake lights.

 

How much did that cost ya?

 

OK, I ran a jumper for the brake switch, nothing happened. I checked for power at the bulbs, nothing. I need to rewire them. Any one know where the wires run for the brakes in a four door? I have to work on it outside in our 5-20 degree weather, Iwant to spend as little time as possible on it.TAI

 

I checked the ohms on the brake light switch, normal. I don't know which wires go to the brake lights from the brake switch, I took most of the car apart and still can't locate the right wires. Does anyone know what wires I have to test to see if I need new wires?

 

Well, since I got no help, earlier( except for the ground location, It is on the rear shelf) I took the paneling out of the car. Now heres an easy one:
I checked the resistance along the whole wire from the brake switch to the lights. It was normal, so no breaks in the wire. Then I checked the wire to chassis. It was also nomal. Then I took the ground for the rear lights off, heres where it gets interesting. I still get the same reading, almost no resistance. So then I took anything that might complete the curcuit apart, the battery, the fuse. And I still get the same reading.

So heres my question, do you think the wire is shorted to the chassis somewhere?

 

the system will not get power until you complete the circuit with the brake pedal. Even with the fuse out you should get the same reading. I am experiencing a couple of the same problems now with a friends car but it only pops a fuse when the pedal is pressed...

 

i just changed my brake light switch and still no lights either, im going to check the the bulbs and wiring around the tail lights.

 

Checking resistance is going to get you no where. Check for power getting to the switch.
Check for power at the fuse. Check for power at the lights.

If you have power at one and not the other then your problem lies between the two. Not that hard to figure out. It's just electricity.

 

i looked around and found a couple broken wires, the colors matched with the wires coming out of the plug on the harness of the bls.
