What is the location and function of the brake light switch for Chevrolet Blazer,S10,GMC Jimmy and Sonoma?

The brake light switch is located on the brake pedal bracket and can be accessed by removing the trim panel beneath the steering column. If there is no voltage, use a test light to locate any short or open between the battery and the switch. If there is voltage at the switch, check if there is voltage on the ground side of the switch when the brake pedal is depressed. If there is no voltage, look for a short or open in the ground circuit and repair it. To replace the switch, remove the trim panel below the steering column, unplug the electrical connector, remove the retainer from the brake pedal pin, and unsnap the switch from the brake pedal pushrod. Installation is the reverse of removal. To adjust the switch, depress the brake pedal, insert the switch into its bracket, and push it in until it is fully seated. Slowly pull the brake pedal to the rear until there are no clicking sounds, indicating that the switch is adjusted. This can be verified with an ohmmeter or continuity tester by checking that the switch contacts are open at one inch or less of brake pedal travel, and closed thereafter.
