When the check gauge light comes on in the 1995 Chevy Cheyenne, it means there is a problem with the transmission. If the truck won't shift in to overdrive, there is most likely a problem with the VSS system. The transmission needs to be removed so the VSS can be accessed.

To change the brake light switch on a 1998 Chevy Cheyenne pickup, first, disconnect the negative battery terminal to prevent electrical shorts. Locate the brake light switch mounted on the brake pedal assembly, usually near the top of the pedal. Remove the electrical connector from the switch, then unbolt and remove the old switch. Install the new switch in the same position, reconnect the electrical connector, and test the brake lights before reattaching the battery terminal.

For the brake wiring on a 1992 Chevy Cheyenne, the brake light switch is typically located near the top of the brake pedal assembly. The switch connects to a wiring harness that leads to the rear brake lights. You'll find a power wire (usually a light green or yellow wire) that connects to the switch, and a wire (often dark green) that runs to the brake lights. Always consult a repair manual or wiring diagram specific to your model for precise color codes and connections.
