I have a 2003 RAV4. The power door lock on drivers side

Customer Question
stopped working. All other doors...
I have a 2003 RAV4. The power door lock on drivers side stopped working. All other doors unlock. I swapped out the driver side actuator. Now when I connect the new actuator to the wire harness the remaining three doors stop working. The drivers door clicks but nothing else happens. When I un do the harness the remains three doors unlock again. Not sure what the issue is even though have new actuator. I'm told maybe passenger side junction box is / ecu unit maybe faulty. Thoughts why this is impacting only drivers door

Are you referring to the switch that controls locks / unlocks the drivers side door. If so. Yes.
Toyota Mechanic: Joe, ASE Certified Technician replied 2 years ago

Yes that is correct.

Is this a new or reman part and oem or aftermarket?

Thanks,

Joe

The only thing we changed / swapped out was the actuator. Nothing else. The new actuator is an after market part.
Toyota Mechanic: Joe, ASE Certified Technician replied 2 years ago

My apologies, I was referring to the actuator being replaced and checking the actual switch. When you use the drivers lock switch with the drivers actuator not connected the remaining three doors all lock/unlock, correct? (using only the drivers door lock switch for this test). And then with drivers actuator connected the others do not, at that point you would want to check power out of the switch at the actuator connector for ground and 12v power and if not present when you press the switch then disconnect from the actuator and test again.

Thanks,

Joe
