Elevator failure: There may be a problem with the elevator itself, causing the switch to not work properly. In this case, maintenance can be carried out by removing the door panel, checking the glass support and the guide rail.
Child lock Lock: In some models, if the child lock button on the cab door is pressed, the glass lifting function of the other three doors will be disabled. Checking and removing child locks can solve the problem.
Circuit faults: including but not limited to, the combination switch cable is off, the main power cable is disconnected, the relay contact is poor or damaged, and the lock switch contact is poor or not closed. This kind of fault requires an overhaul of the circuit.
Harness failure: For example, terminals in the harness may become loose or exit the connector, resulting in a circuit disconnect. In this case, you need to repair loose terminals or replace damaged wiring harnesses.
Fixing these problems usually requires professional diagnosis and maintenance. For non-professionals, it is recommended to contact a professional car repair service for inspection and repair to ensure safety and effectiveness.
