If any wiring is damaged replace them.
Passenger side door locks not working.
This morning the same 50 of the time.
The only part that these two have in common is the master switch.
Again if one door doesn t work but others do the problem could be with the door lock solenoid.
Also the door locks don t work when the drivers door is open.
The solenoid is bad.
If it s not sending a signal the fob will likely have to be replaced.
This is a cheap and easy fix.
The most likely cause of your problem is the master switch in the drivers door.
If one door doesn t work but others do the problem could be a blown fuse.
The windows and the locks are on two separate circuits.
Assuming it s the front passenger s side door we know that the smart entrance control unit and fuses are good because the rear locks work.
And it is the front door right.
Of course it is also possible that the wiring harness between the driver side door and cowl is.
Later on they worked 50 of the time you tried.
Once i open the door more than a quarter of the way the locks stop responding.
Follow lead wire to the door lock actuator.
A fuse is blown.
When a door ceases to lock and unlock at the press of a button it often means that the door s lock actuator has given up the ghost.
So yesterday my driver side door handle sensors for lock and unlock stopped working.
Pop the window and door lock switch panel off the door handle.
Replacing the fuse will correct the problem.
All times tested i could walk to the passenger side and it would work no issue.
The lock actuator consists of a small electric motor that drives.
I could walk around to the passenger side and they worked just fine.
Upon discovering this i tried to lock and unlock the doors from the passengers side lock switch the passengers side stops working too when the drivers door is open.
You said drivers side passenger door lock.
Replacing it may require removing the car door panel.
If the result of this does not yield any results continue to step 2.
Unplug the door lock connectors and inspect to make sure nothing stands out.
