2. Check the power seat belt switch. The power seat belt switch is responsible for activating the power seat belt motor when the door closes. If the switch is not working, the motor will not be activated and the seat belt will not retract. To check the switch, press the switch and see if the motor activates. If the motor does not activate, the switch may be faulty.
3. Check the power seat belt wiring. The power seat belt wiring is responsible for providing power to the motor and switch. If the wiring is damaged, the motor and switch will not be able to function and the seat belt will not retract. To check the wiring, inspect the wires for any damage. If you find any damaged wires, repair them or replace the wiring harness.
4. Check the power seat belt mechanism. The power seat belt mechanism is responsible for retracting the seat belt. If the mechanism is damaged, the seat belt will not retract. To check the mechanism, inspect the gears and other components for any damage. If you find any damaged components, repair or replace them.
If you are unable to fix the power seat belt device yourself, you can take your car to a mechanic for repairs.
