Thanks for visiting Just Answer,
Sounds like you have a problem with the mode actuator.

1. Remove the Left Hand (LH) hush panel and the LH knee bolster.

2. May also need to remove the steering column for more access.

3. Tap on the mode actuator, check for operation.

4. Check mode actuator connection, wiggle connector, check for operation.

5. Remove the screws that hold the motor in place only.

6. Pry this motor off the shaft, leave the cam and levers in place.

7. Move the cam, make sure that the levers/doors move freely.

8. If OK, replace the mode actuator. NOTE: It's wise to replace the motor only, difficult to align the cam/levers for the mode actuator.
