Hello, my 2001 bmw x5 is having issues here and there with what I believe is the brake switch, when I start the car my brake lights are on when my foot is not on the brake and my gas pedal does nothing. Is this a brake switch issue? I had also pulled the fuse in the glove box for the switch and nothing changed. I had just recently bought the car and it has a aftermarket sound system in it which I believe might be part of the problem. This problem isn't always constant, as I sure the next time I go to it, it may be fine. But if it's a faulty switch I would like to be able to replace it so I can stop leaving it sit. Any help or leads I the right direction are greatly appreciated.
