The door lock on RR locks does not lock sometimes with remote R switch on drivers side!! Can be done manually but, just getting old checking that door everytime I get out of truck. Where should I start trouble shooting issue? Thanks for any help!!!

 

Does it move at all? Is it hard to lock manually or do you think there is no power going to it? I would start by pulling the panel and checking for power at the lock actuator when the remote is pressed, of course making sure all fuses are good before.

 

Not hard to lock by hand and yes it has power to it because it moves a little but not all the way. Sometimes even works but more often then not doesn't work!!!
