Switch, Stop Lamp: Installation
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.
Never remove or install the brake lamp switch while the brake pedal arm is disassembled from the brake booster push rod.
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.
Be certain that the brake pedal bracket is not bent or damaged before installing or reinstalling a brake lamp switch. Inspect the brake switch tab location making sure its in the proper location indicating that the switch is not ineffective.
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).
Examples of what to look for on the condition of the switch. Normal operational brake lamp switch to be used for installation (3). Ineffective brake switch due to the switch tab being sheared off (1). Ineffective brake switch due to the switch tab being offset (2).
- Position the brake lamp switch near the brake pedal support bracket on the dash panel under the instrument panel.
- Align the tabs on the brake lamp switch locking collar with the keyed hole in the brake pedal support bracket.
- Holding the brake lamp switch perpendicular to the support bracket, insert the tabs on the brake lamp switch locking collar through the keyed hole in the support bracket until the switch housing is firmly seated against the bracket.
- Rotate the switch housing counterclockwise about 45° to engage the tabs on the locking collar with the support bracket.
- Connect the body wire harness connector (1a) to the connector receptacle on the switch (1b).
- Install the drivers side floor vent. Refer to FRONT FLOOR DUCT, INSTALLATION .
