Door lock won't work

[ViperZero]

Hey guys, I got another question that I need help with. The door behind the driver side won't unlock or lock with remote or door switches about 80% of the time. I have taken the door panel off and can't get to the locking mechanism. Any thought or tips to fix would help.

When I replaced the battery last week and it worked fine and when I reset the cel for gas cap it worked fine again. I'm kinda stumped with this one.

Take the panel off and check the connection at the window motor. check for voltage at the wire when the window won't move. Just saying it could be at the /or the motor. just a thought.......
