VW Bora TDINovember 26, 2013Central locking works on the front doors, one back door opens sometimes,the other wont work at all, Any ideas please Share Tweet Pinterest Keywords:BoraElectricalpower door locks 1 thought on “VW Bora TDI” Freeautomechanic November 26, 2013 at 11:33 am First thing i would do would be to remove the door panel and check for voltage at the door locks when they are not working. If you have voltage at the door locks and no operation, replace the door lock actuator. If you do not have power, check for power coming out of the central control switch. No power coming out when switch is activated.. replace switch. If you have power coming out… time to start tracing wires. FreeAutoMechanic Tip: Most of the breaks in wiring, when dealing with power windows or locks, occur where the door hinges. Comments are closed.
