Switch, Stop Lamp: Removal

WARNING: This page is about a different variant/trim than selected.
WARNING:

To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.

CAUTION:

Never remove or install the brake lamp switch while the brake pedal arm is disassembled from the brake booster push rod.

CAUTION:

Do not depress, lift or move the brake pedal during brake lamp switch removal to avoid switch damage. Do not depress, lift or move the brake pedal during brake lamp switch installation to avoid improper switch adjustment.

NOTE:

If damage to the switch is present for any reason, the switch is to be replaced. If a switch is removed and the plunger length differs from a new switch, the switch should always be replaced and not reinstalled. The nominal height for a new switch (tip of the plunger to the body of the switch) is 16.9 mm (0.67 inch).
