  Q: How to Replace a Brake Light Switch for Cruise Control on Chevrolet HHR?

  A: The first step to replace the cruise release switch requires instrument panel (I/P) sound insulator removal. First detach the cruise control release switch from the switch retainer while rotating it in a counterclockwise direction. Turn off the power at the cruise control release switch electrical connector and then unfasten the switch retainer from its bracket position on the pedals. Uninstall the switch retainer onto the pedal bracket while using its indexing arrow for orientation if the part was previously removed. Hook up the cruise control release switch electrical connector after which you should refill the Brake Pedal until the system shows full release. Secure the cruise release switch in the retainer by rotating it clockwise until complete while keeping the switch plunger against the rubber bumper without letting the bracket or switch contact arm deflect the pedal. Use a meter to check the switch barrel to switch contact rubber bumper clearance and verify that it should not exceed 1.2 mm (0.047 inches). Commercial vehicles must open their cruise release switch and stop lamp and torque converter clutch (TCC) switch at 25.4 mm (1 in) pedal travel distance so these components open either at the same time or before any braking operation starts. Before cruise control activates its disengagement the Brake Pedal should travel a maximum of 25.4 mm (1 in). The final step of the service consists of reinstalling the i/p sound insulator.
