Remove any covers or panels obstructing access to the parking brake mechanism.
Examine the parking brake cables for any signs of wear or damage; replace if necessary.
If the parking brake is electric, check the actuator for proper operation; replace if faulty.

4. Test and Replace Switch

Locate the parking brake switch; disconnect the wiring harness.
Using a multimeter, test the switch for continuity when engaged and disengaged.
