Unclip the lock rods and unplug the wiring harness. Door lock systems operate the actuator by toggling positive negative voltage to the actuator. Plug in the wiring harness and lock rods. Once the actuator is free from the door it should be hanging by the interior lock rod.

Removing the door latch assembly was a pain. Way cheaper than the whole assembly. That motor as posted above is 30. Then use your test light or digital meter to check for power and ground at the connector when you operate the lock unlock switch.

There was no room and led to many nicks and cuts. Pull the actuator so you can get a handle on the electrical connection. When you push it up all the way 1 it will push itself off of the actuator. Transfer the mounting bracket and dust cover to the new lock actuator.

It has a little purple plastic piece on the top that you need to insert a broad flathead into and push up. You should see the voltage polarity toggle with each switch activation. Again the difficulty was not bad to replace the motor.
