I have a mini van... My break lights turn on randomly while I'm driving but the break is not on.?

Question

Why does this happen? The break light turns on and I know the break is not on. It usually happens after i press on the break at stop signs or when im decreasing speed quickly.

Answer 1

Have your local auto repair shop either adjust or replace the brake light switch that is located under the dash.

Answer 2

either there is a short in your break light wire or the brake light switch mounted behind the brake pedal is sticking and will not release the tab.  They are usually fairly easy to replace, just more of a pain in general.

Answer 3

Adjust brake switch or replace weak return spring

Answer 4

It could be a short in the electrical system. A dealer can check it for you.

Answer 5

Did you check to see if there was something in the trunk that may be against the wiring? Since you said it happens after there has been a change in motion (stopping, decreasing speed) there may be something rubbing the wiring or creasing it. I don't know how the lights are in your mini van, but this did happen to me once in my car. If this isn't the problem, then off to the garage since this is a hazard for you and others. Good luck and be safe.

Answer 6

there is a brake light switch under the dash that contacts the arm on the brake pedal. check it and see if it is loose in it's mount
