How to Replace Brake Light Switch 05-07 Chrysler 300

Difficulty: Beginner · About 25 min · Chrysler 300

Replace the brake light switch on a 2005–2007 Chrysler 300 and confirm the brake lamps respond correctly to pedal movement.

Steps

1. Lower the pedal insulation

   Park with the ignition off and remove the clips securing the insulation beneath the dashboard. Lower the insulation enough to reach the brake light switch above the pedal arm.

2. Remove the old switch

   Rotate the switch counterclockwise to release it from its bracket. Unplug the electrical connector by releasing its lock, then remove the switch without pulling on the harness.

3. Install the replacement switch

   Connect the wiring plug and align the switch with its bracket. Rotate it clockwise until it locks into place, then ensure the pedal contacts the actuator correctly without preloading it.

4. Test brake lamp operation

   Press and release the brake pedal while checking that the brake lamps illuminate and switch off reliably. Refit the insulation and clips after confirming the switch works.

Check your vehicle’s repair manual for exact specifications and fit.
