Nissan 80501-4BA0B Front Left Door Lock Actuator

This process applies to both front and rear doors. Begin by removing the power window switch, followed by the door trim panel and watershield. Next, take out the door window module. For models with the Intelligent Key system, disconnect the electrical connectors to the door antenna and door request switch, then remove the harness retaining clip from the door outside handle bracket. Pry out the door side grommet to access the door key cylinder trim panel bolt, and disconnect the key lock rod from the lock cylinder from inside the door. Remove the door lock cylinder and cover assembly while pulling the outside handle forward; if the key lock rod cannot be disconnected from the inside, pull the door lock cylinder out enough to disconnect the key cylinder connection rod before removing it. Pull out the outside door handle and slide it towards the rear of the vehicle for removal, then carefully remove the front and rear gaskets. Next, take out the door lock assembly mounting bolts, slide the outside handle bracket towards the rear of the vehicle, and remove the assembly. If applicable, disconnect the door lock assembly electrical connector and separate the outside handle cable from the outside handle bracket. Installation follows the reverse order of removal.

Every 3000 miles of operation or in every third month of its use the hinges and latch assemblies on the doors, the hood and the trunk should be coated sparsely with the light oil or the lock lubricant. Furthermore, the door latch strikers need to be greased, but lightly, so that they do not become too slippery to turn when the door is locked. It is also good to keep the lock of the door and trunk well lubricated using the spray-on graphite lubricant.
