I have a 91 BMW 318is and the brake lights are always on. I checked the switch under the pedal and its not stuck and seems to be functioning. I need to know what the problem might be?? and if I can fix it myself as I really do not have much money to take it to the dealer or a shop.
Thanks for any help

It will be batter if u will go to the garage.

There are cool DIY sites around though I am cant specify which. If you come across one and is in need of affordable Canada auto parts (http://www.autopartsway.ca), call 1(866)530-5789.

make sure the leads on switch arent reversed just switch them around and see if the lights go off

Dont take any chance just go to the nearest body shop. They will help.
