The brake light switch is mounted in front of the brake pedal and is responsible for activating the brake lights when the brake pedal is pressed. The brake pedal switch can fail a few different ways. You may have a brake light warning lamp illuminate in your instrument cluster, indicating a problem with the brake light circuit. If none of the brake lights illuminate and the fuse is fine, the brake light switch is most likely the cause. I have also seen where the brake lights stay on all the time, and the warning lamp is also on. If the lighting control module sees a fault with the brake light switch, it will turn the brake lights on all the time. This is for safety. There are a few things to remember when checking your brake light switch: check the fuse (find location using fuse index in fuse panel), check the brake light switch adjustment (see steps below for how to adjust), inspect the brake light bulbs and use a high impedance digital volt ohm meter (DVOM) when testing the circuit.

The clutch switch is used to notify the DME that you pressed the clutch pedal. The signal generated by the clutch pedal switch is used for engine starting, engine performance and traction / ABS control. The clutch pedal switch is mounted to the side of the clutch master cylinder. Replacing it is quite easy, and I will show you how a little later in this tech article.

Remember that your car may have been serviced before and had parts replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Our vehicle may vary slightly from yours as models do change and evolve, as they grow older. If something seems different, let us know and share your info to help other users.

Remove the lower left side instrument panel trim. See our tech article on lower left side instrument trim panel replacing.

The brake light switch (red arrow) is mounted in front of the brake pedal, and the clutch switch is mounted to the clutch master cylinder (green arrow).

The brake light switch (red arrow) is mounted in front of the brake pedal, and the clutch switch is mounted to the clutch master cylinder (green arrow).

Working at the front of the brake pedal, disconnect the brake light switch electrical connector by pulling the connector straight up and out the brake light switch (red arrow).
Figure 2

Working at the front of the brake pedal, disconnect the brake light switch electrical connector by pulling the connector straight up and out the brake light switch (red arrow).

Remove the brake light switch by sliding the switch (green arrow) out of the mounting bracket toward the rear of the vehicle (red arrow).

Remove the brake light switch by sliding the switch (green arrow) out of the mounting bracket toward the rear of the vehicle (red arrow).

Once the electrical portion of the switch is removed, pull the mount / adjuster out of the mounting bracket by releasing the tabs (green arrow).
Figure 4

Once the electrical portion of the switch is removed, pull the mount / adjuster out of the mounting bracket by releasing the tabs (green arrow).

The new switch will come assembled.
Figure 5

The new switch will come assembled. Separate the switch (red arrow) from the mount (green arrow).

Press the mount / adjuster (red arrow) into the pedal mounting bracket.
Figure 6

Press the mount / adjuster (red arrow) into the pedal mounting bracket. Then slide the switch in (green arrow). Press the brake pedal down and hold it. Then slide the new brake light switch all the way into the mounting bracket. Then, slowly release the brake pedal and let it come in contact with the brake light switch. As it makes contact, the brake light switch will automatically adjust to the correct position. Connect the electrical connector and check the brake light operation.

Working at the side of the clutch master, disconnect the clutch switch electrical connector.
Figure 7

Working at the side of the clutch master, disconnect the clutch switch electrical connector. It is located on the fender side of the clutch switch. Grab the electrical connector (red arrow) and pull it straight out of the clutch switch.

To remove the clutch switch from the clutch master cylinder, grab the top (red arrow) of the switch near where the electrical connection is.
Figure 8

To remove the clutch switch from the clutch master cylinder, grab the top (red arrow) of the switch near where the electrical connection is. Pull it away (green arrow) from the clutch master cylinder. This will unclip the switch and release it from the clutch master cylinder.

This photo shows the clutch switch (red arrow) being removed from the clutch master cylinder (green arrow).
Figure 9

This photo shows the clutch switch (red arrow) being removed from the clutch master cylinder (green arrow). To install the new switch, slide the rear of the switch into the clutch master cylinder. Then press the area near the electrical connection into the clutch master cylinder. The switch will snap into place. Once installed, connect the electrical connector and reassemble the trim panel. Check that the clutch switch is functioning properly by starting your vehicle, and you are done.
