Possible causes
- Open circuit in signal cable M1-
- Blown fuse (passenger compartment fuse 4)
What you can do
- 1Make sure passenger compartment fuse 4 is intact and sits properly in its holder.
- 2Check that the wiring between the control module and the motor is firmly seated in its connectors and not chafed, and move it gently while the seat is run.
- 3Use a multimeter to check that the wiring between the control module and the motor has no open circuit.
- 4If the fault remains, have a workshop check the motor and the control module.
