2009 F-150 Power Door Locks
Crew cab left rear door lock quit. Got new factory actuator, still nothing. Is there a relay or fuse somewhere? Which wires are lock/unlock, which are door ajar sensor? Anybody have a schematic of the system? Thanks.

violet/grey and grey/brown are the lock circuits, green and black/violet are the door ajar circuits. Look for broken wires in the rubber accordian at the door jamb.

Problem Solved
took door harness out. nearly all the wires cracked/broken near connector at door post. too short to fix so eliminated connectos(s) and butt spliced in boot. note to ford engineers....the bent plastic piece used to train the harness in the boot is a bad idea. it concentrates the stress at the ends of the plastic breaking the wires at both ends. BTW this model actuator does not have the overload protection that everyone seems to have problems with.
