2. Remove the mounting screws of the switch to be replaced and remove the faulty switch.
3. Pull the wires of the switch being replaced out of the main wire harness and disconnect them from the connector.
4. Pull the wires of the switch being replaced out of the main wire harness and disconnect them from the connector.
5. Press the tabs at the rear of the connector and remove the cover. At the front of the connector, insert a small screwdriver or pin and depress the lock retaining the terminal, then remove the terminal from the rear of the connector.
