Check the brake light switch properly before assuming the switch is faulty, if the brake lights aren't working, check the fuse and the bulbs. If they're operating properly, check the switch for voltage output. Scan around for an open circuit between components like the fuse block and switch, if there's no voltage. If there's power, apply pressure on the brake pedal and check the voltage on the other side. Purchase a new switch if there is no voltage. If there is voltage but the lights aren't working, find an open circuit between the switch and the lights, remove the electrical connector, rotate it counterclockwise to loosen it from its holder, and remove the switch from the holder. Setting up the switch starts by inserting it into the holder, pushing it in until it touches the rubber stop, and rotating it clockwise to secure it in place. make sure proper clearance to the rubber stop is (0.020 to 0.098 inches). Once you are done putting everything back together, test the brake lights before operating it.

To remove the brake light switch, start by moving the driver's seat fully to the rear for maximum working space. Disconnect the wiring plug from the brake light switch located at the top of the brake pedal bracket, then loosen the switch locknut and withdraw the switch from the bracket. For refitting, reverse the removal process. After fitting and reconnecting the switch, check its operation by having an assistant observe the brake lights while you push the brake pedal in by hand approximately 5 to 10 mm, adjusting the brake light switch so that the lights just turn off. Release the pedal and slowly press it again to ensure the brake lights illuminate before the pedal has traveled 15 mm. Additionally, the brake light can be adjusted by measuring the clearance between the switch plunger and the top of the pedal, comparing it with the specified measurement.

When the brake pedal is in the fully released position, the switch opens the brake light circuit. When the brake pedal is depressed, the switch closes the circuit and sends current to the brake lights.
