What are the reasons for the failure of the electric adjustment of the Tiguan seat?

[StIsabella]

Electric seat adjustment failure may be due to a damaged adjustment switch, a burned-out adjustment motor, or a circuit fault. Many cars are equipped with electric adjustment seats, which have internal electric adjustment mechanisms. If these mechanisms are damaged, the seat cannot be adjusted. The main faults and troubleshooting methods for electric seats are as follows: 1. The control system does not work or makes noise: ① Check the grounding condition of the solenoid valve to the body. If the grounding is poor, the control system will not work. ② Use a test lamp to check the circuit breaker on the fuse panel. If the indicator light is on and there is a clicking sound from the seat relay, the fault may lie with the motor. ③ Before inspecting the relay and motor, also check the voltage at the switch, as the fault may also be with the switch. 2. The seat motor runs, but the seat does not move: Check whether the rubber coupling between the motor and the transmission is worn or damaged.
