If the result of this does not yield any results continue to step 2.
Passenger side door locks not working.
It s either the driver s side or the passenger s side.
A fuse is blown.
If it s not sending a signal the fob will likely have to be replaced.
Follow lead wire to the door lock actuator.
If one door doesn t work but others do the problem could be a blown fuse.
Unplug the door lock connectors and inspect to make sure nothing stands out.
I could walk around to the passenger side and they worked just fine.
The windows and the locks are on two separate circuits.
If any wiring is damaged replace them.
Once i open the door more than a quarter of the way the locks stop responding.
Remove switch panel and inspect wiring.

You said drivers side passenger door lock.
Pop the window and door lock switch panel off the door handle.
Also the door locks don t work when the drivers door is open.
The lock actuator consists of a small electric motor that drives.
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.
Again if one door doesn t work but others do the problem could be with the door lock solenoid.
And it is the front door right.
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.
This morning the same 50 of the time.
So yesterday my driver side door handle sensors for lock and unlock stopped working.
This is a cheap and easy fix.
The solenoid is bad.
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.
Replacing the fuse will correct the problem.
The most likely cause of your problem is the master switch in the drivers door.
Isn t that a contradiction in terms.
All times tested i could walk to the passenger side and it would work no issue.
Later on they worked 50 of the time you tried.
