Faulty Brake lights...(not the bulbs/fuse)?? help?

[gpgold]

Howsit okes!

So I need a little advise on what to check next.

I found out only one of my brake lights is working on my E36 (right side) So the left and middle ones are not working. First thing I did was check the fuse...changed it, but the problem is still there....next I changed the light bulbs....still no light...connections look good as they are hidden behind the plastic boxes and have never been removed before....

Please tell me what else can I check?...the Girlfriend is getting upset having to come out to push the brake every ten mins....:hammerhead:

Thanks for any advise!:thumbsup:

strip open the wiring loom where it bends when you open and close the bootlid, those wires eventually break inside due to the bending everytime you open/close the bootlid.

The contacts in the plug that goes onto the main board the lights plug into also melted on my e36 once, just opened it up and did a DIY on it.

The E46's had a poor ground connection on the wire that connect to the tail light circuitry. Lay a separate decent earth to the tail cluster if you've exhausted the other options.

Agree with Hellas check the ground if it is clean and properly tighten....
