1994 Mitsubishi Galant door locks not operation correctly. Two back doors will only lock if manually locked at the back door lock - won't lock when driver door key or driver master lock (all doors) is used inside.
Hi
there is a motor placed inside the doors for the operation of the central lockin system. when you open the door by key this motos is activated and all door locks are released. your problem may because of this motor is failed.
cause of the failure
1.the wire going to the motor may be chopped off.
2.the junction box connecting the wires may be damaged.
3.fuse may be blown out.
4.motor itsef damaged.
so please check weather power is coming to the motor using multi meter. if the power is not coming to it then the problem is with the wires. if the power is coming to it then problem is with the motor.
please vote me if my answer was useful to you.
