Replacing the fuse will correct the problem.
Passenger side door lock wont work.
If one set of switches can control the windows it s likely the switch on the opposing side that needs to be replaced.
Again if one door doesn t work but others do the problem could be with the door lock solenoid.
The solenoid is bad.
Re install the door panel using the reverse steps.
Sometimes something as simple as the actual door lock switch can fail and not operate.
The battery died and had to be replaced.
A fuse is blown.
If the driver door lock switch doesn t work try the passenger door lock switch or any other door.
In some vehicles the cable that connects the door lock actuator to the inner door handle may be built into the actuator assembly.
This issue also indicates a bad lock actuator.
This is a cheap and easy fix.
Replacing it may require removing the car door panel.
The driver side window was stuck down and all door locks would not work all the other windows went up and down as they should but still no drivers window or door locks.
Locks work from the switch but not the remote.
I checked all fuses even 68 relay but still could not find problem i drove 18 miles in 30 degree weather at nite got home and was very confused with this truck.
Luckily this is the easiest and cheapest items that can go wrong.
In most cases the problem with a door lock actuator is limited to only one door.
When we replaced the battery the door locks started unlocking and locking by themselves with the key in the ignition and without the key in the ignition.
If they work then you ve narrowed down your problem.
One of the easiest ways to diagnose the switch is by trying to use other door locks in the car.
In some cars a failed door lock actuator may lock but won t unlock or the other way around.
I already disconnected the driver and passenger side door lock switches and when disconnected the back doors still locked and unlocked by themselves.
The door lock works in only one direction.
