BMW E36 brake switch replacement

Difficulty Level: 3
Difficulty scale: Adding air to your tires is level one
Rebuilding a BMW Motor is level ten

     One common failure on the BME E36 vehicles is the brake light  switch. Have you noticed that the brakes lights fail to come on when you press the pedal? Itís possible that switch may need to be replaced.  In this tech article, we will discuss replacement of the switch.

     The first step is to remove the screws that hold the plastic panel on underneath
the steering column. This will allow you to remove the panel to gain access to the switch.

     Now, look up under the dash. The brake light switch is located underneath the top of the brake pedal arm, under the dash. When you have located the switch on the brake pedal, remove the wire harness that plugs into it, and set it aside.

     Once you have the wire harness off, youíll see that the switch seems stuck in place. What you need to do is first break the small red tab on the switch, and then start the engine. Starting the engine will make it easier to push the brake pedal down. Youíll need to push the pedal to disengage the switch. This will free up the switch.  Once the old switch is free, simply pop the new brake switch into the bracket, and press the red tab on the switch to lock it into place. Once the switch is in place, re-connect the wire harness to the switch.

     Now is a good time to check the switch.  Turn the car on and have a helper check the rear lights. Now simply push the brake pedal like you would on any car.  Do the lights come on? If not, recheck the steps listed.

     Once the new switch is in, and you have verified that the switch is working, the last step is to re-install the lower steering column panel under the dash.
