The issue that I'm having is that my brake lights are always on when the key is turned. My third brake light works with the switch as it should. Due to the brake lights stuck on, I have also lost cruise control. Has anyone else had this problem?

Good afternoon,

I would suspect the stop light switch as it controls the brake lights as well as the cruise control.

1. Remove the left sound insulator.
2. Remove the pushrod retainer (3) from the brake pedal pin (4).
3. Remove the stop lamp switch (1) and the pushrod (2) from the brake pedal pin (4).
4. Disconnect the stop lamp switch (1) electrical connector.
5. Remove the stop lamp switch from the vehicle.
