Repair door lock actuator

 

The problem with the door actuators it seems is that there is a microswitch inside the actuator that goes bad and develops a resistance between the contacts that prevent the motor from getting enough current to lock and unlock the doors.

Remove the door lock actuator from the door.  Use the proper repair manual to help you accomplish this.

Carefully remove the cover from the actuator and this will allow you to see the microswitch.

Carefully de-solder the microswitch.  It will be marked as far as which contact is NO, NC, and common.

Go down to your local electronics store and get one that looks close to the one you have.

Solder it back in and put the door back together.

FIXED!
