Mustang Door Lock Actuator Install (87-93)

How To Install Fox Body Mustang Door Lock Actuator (87-93)

An inoperative door lock actuator can be a real pain to deal with. With this simple install you can make your mustang's door unlock and lock as it should.

Now, one special feature about these door lock actuators is an NPR rubber boot. This is exclusive to 50 resto. This boot will not degrade, and will not allow water to penetrate the actuator, which is the main problem that plagues other aftermarket lock actuators. Here are the tools we're going to need for this install.

1. Remove the actuator from the box and set the parts on a work bench. You will find a few different shafts included. For your Fox you will need to select the S shaped shaft. Slide this into the end of the actuator and the set the pin with a hammer against the work surface.






2. Check the rivet hole for any casting flash, using your drill and a 1/4" drill bit, run the bit in the hole a few times. This will make the rivet sit flush and make the install easier.





3. Next, move the car and remove the door panel from the car.





4. On the center of the door jam, use your drift or punch and your hammer and knock out the mandrel from the center of the rivet holding the actuator in place.





5. Using a 3/8" drill bit, drill the remaining portion of the rivet out from the door. Make sure to only drill through the head of the rivet, do not go too deep. Once the rivet if free the actuator is ready to come out.





6. From inside the door lift up on the actuator and pull it away from the lock rod that is attached. Once you have it separated, unplug the electrical connector and then you can discard the old actuator assembly.





7. With the new actuator in hand, plug in the electrical connector.





8. Slide the S rod back into place on the door lock rod.



9. Set the actuator into place and put the rivet in through the door. Grab your rivet gun and then set your rivet.





10. Check for operation once the rivet is set and make sure the lock rod moves freely and there is no binding in the system.





11. If everything is good, then reinstall the door panel and repeat these steps for the other side.
