The passenger side door lock does not unlock or lock with remote. Drivers manual unlock or lock button does not operate passenger door. Passenger door does lock others manually.

 

Before tearing the door card off and diving in to the lock assembly try a good spray lubricant on the assembly and be generous with it. The doors other than the drivers don't see as much action and will start to stick.
Try the lubing and report back and we can go further if necessary.

 

Gave it lots of WD40, with no results.

 

Should have said front passenger door. Rear ones work fine.
