Disconnect the electrical connector from the brake pedal switch.
Remove the switch using a socket or wrench, and replace it with a new one.
Reconnect the electrical connector and replace the cover.

4. Inspect the Transmission Shifter

Remove the center console cover to access the gear shifter assembly.
Check for any obstructions or mechanical issues preventing movement.
If necessary, lubricate the shifter mechanism or replace any damaged components.

5. Electrical Connection Check

Reconnect the battery and check all electrical connections related to the transmission.
Ensure connectors are secure and free of corrosion.
Use a multimeter to test the continuity of the wiring harness.
