To test the brake light switch, the brake pedal should be pressed, if the brake light does not light up the brake light fuse and the brake light bulbs in both tail light assemblies and the high-mount brake light should also be checked. If both fuse and bulbs are fine, this suggests the problem is with the brake light switch, and this is located at the upper part of the brake pedal; the switch electrical connector should be disconnected and the meter probes placed across terminals B and C and there should be couple when the brake pedal is pressed and no couple when released-if the switch does not operate in this manner, it should be replaced. To remove the switch, first, it is necessary to open the electrical connection, then to remove the locknut located in the pedal part and unscrew the switch from the bracket; to install-vice versa. For adjustment, turn the brake light switch locknut clockwise counterclockwise until switch no longer touches the brake pedal, then make adjustment on the pushrod so that the height of the brake pedal from the floor is correct your screw the locknut tight. Insert the plunger of the brake light switch until it rests against the spring and backlash, turn the switch clockwise until the backlash is at the 1/2 turn position, then tighten the locknut as required. Last but not the least, depress the pedal and check the free play or lack of it and see whether the brake lights are functional and whether the freeplay is to the specified dimension or not.
