All my door locks worked, then out of the blue the rear doors pass/drvr and rear access stopped locking. But if I manually lock the doors inside and then unlock them they work.. So it seems that the actuators work. Is there relays for each door? At the fuse panel there is a large fuse that says door lt on it. I guess it is good since the front doors lock. Any help or advice on this problem is greatly appreciated thanks!

 

Welcome to the forum. The LOCK and UNLOCK relays in the I/P fuse block are for the rear doors and liftgate. Maybe the control coil in the LOCK relay is burnt out?
