Brake Light Switch: Service and Repair
REMOVAL1. Disconnect the wire harness at the connector from the stoplight switch.
NOTE: Locking tab on connector must be lifted before connector can be removed.
2. Remove the hairpin retainer, slide the stoplight switch, the push rod and the nylon washers and bushing away from the brake pedal, and remove the stoplight switch by sliding it up/down.
NOTE: Since the side plate of the stoplight switch nearest the brake pedal is slotted, it is not necessary to remove the brake master cylinder push rod and one spacer washer from the brake pedal pin.
INSTALLATION
Fig. 3 Stop light switch replacement:
1. Position stoplight switch so the U-shaped side is nearest the brake pedal and directly over/under the pin. Then slide stoplight switch up/down, trapping the master cylinder push rod and blade bushing between the stoplight switch sideplates. Push stoplight switch and push rod assembly firmly toward brake pedal arm. Assemble outside white plastic washer to pin and install hairpin retainer to trap whole assembly.
CAUTION: Do not substitute other types of pin retainers. Replace only with production hairpin retainer.
2. Assemble the wire harness connector to the stoplight switch and install the wires in the retaining clip.
NOTE: Stoplight switch wire harness must have sufficient length to travel with stoplight switch during full stroke of brake pedal. If wire length is insufficient, reroute harness or service as required.
3. Check stoplight switch for proper operation.
