Door Lock Repair
The
same actuator can be found in 1979-93 Mustangs and should be in almost
all Fords from 79-93 (with some minor swapping, see text below). I bought
one from a '85 Bronco-II for $15, and had to use my old rod (other one
was about 3 inches longer).
Key
not working ?
If
your key can't unlock or lock the door because it can't turn, then it's
usually a sign of a frozen door lock motor.
Once you have determined that the actuator is no longer working,(or to check it) Pull the interior cover off the door (2 bolts in armrest, mirror cover, handle cover, plastic tabs and screws, you don't have to take the screws off of the door lock switch panel).
First
check to see if the actuator (GREEN)
is the problem.
-
Check if it's getting current when pressing Lock or Unlock.
Squeeze
your hand in (caution, sharp edges) and disconnect wire from actuator.
With a flat screwdriver pry the actuator's pegs out of the plastic
retainer (YELLOW) that's holding
it to the door, be careful not to break it.
Don't
bother drilling out the rivet that holds the plastic thing
to the door, you will waste your time and a good drill bit.
Once
the actuator is freed from the plastic bracket the tricky part is to
pull its rod out of the lock mechanism.
It has a curved top so lift and turn it until you've pulled it out.
Be careful, don't damage the plastic thing that's holding the rod to the lock mechanism,
or the rod itself, you might need this rod if the "new" one is a different length.

If
you acquired an actuator from another Ford vehicle it will be the same,
the rod length and wire socket may be different.If the rod length is different (Bronco's were longer) pry the small cover/retainer up and pull the rod out, it will spin up and out. DO NOT LOOSE THE VERY TINY BEARINGS!!! There are 3 of them.
Insert your old rod from the original actuator and put everything back in reverse. When you have the retainer (cover) snapped in, make certain the rod spins up and down, to test if the bearings were replaced correctly.
If the wire socket is different, keep the new one on and splice it into the original wires in the door.
