I have a 1994 325i... Every once in a while I get and indicator that says brake light failure. I notice this mostly when it's wet outside, and if I turn the car off and back on again, it resets itself. After replacing the tail lights 2 times (only driver's side and very expensive) I found it to be the connector contacts. The tail lights have a male/female connector to the circuit board, down in the female part of the connector you will see circular "tube" connectors that are attached to the wires going into the female connector, that the male connector should be touching when it is inserted. Some of these may have come loose or gotten dirty. I've replaced several of these (not easy to find so take one with you to the electrical store), Cleaned them well with contact cleaner, and haven't has a problem since. NOTE: When replacing them do ONE at A TIME so you can strip the wire and put the connector on clean...and put it back where you got it from... if you take them all out, it's a pain figuring out which wire needs to go in which hole!

Where the brake light relay is on a 2000 mercury cougar or why the brake lights wont work the fuses and lights are good?
Check the brake light switch first. It is usually near the brake pedal under the dash. A bad turn signal switch can also cause this if the brake lights are also turn signal lights. If the brake lights are independent of the turn signals then disregard the switch problem. A good wiring diagram will help to diagnose the problem also. Check with dealership mechanics as they have access to diagrams.
