Don't let a broken or stuck power door lock actuator keep you from enjoying your Fox Body Mustang. Replace them with a 5.0Resto Mustang door lock actuator kit or better yet purchase one of the many 5.0Resto Restoration kits to save money and time on your next project. Follow along in this video as Jmac shows you how to install new power door lock actuators in your Pony.
Mustang Door Lock Actuators are problematic to say the least, especially on the Fox Chassis cars. As I stated in my Top 10 Fox Mustang Restoration Parts Blog
, Mustang Door Lock Actuators are typically in one of three conditions. They operate properly, the key still works in the door but nothing happens when you hit the unlock button, or the key won't even turn in the Door Lock Cylinder, the Door Lock Knob is frozen in the unlock position & nothing happens when you hit the Power Door Lock Switch.
Take a look at our install video or go further down for a written install with pictures.

Today we'll be working with my 93 Mustang LX Coupe, code-named Project Red, White, & Puke. I found myself in Door Lock Actuator situation #3 as I couldn't even lock my doors. While I can't imagine that anyone would even want to break in to a turd looking like this, it's better to be safe than sorry. Follow along as I install our Mustang Door Lock actuator Kit
, part # LRS-21842K. It will work on 79-93 Fox Mustangs.
Step 1, remove the Door Panel. For a step by step guide on this, check out my Mustang Door Panel Removal & Replacement Blog
Next, locate the Door Lock Actuator Retaining Rivet. Most of the time the shaft of the rivet is still lodged in the rivet head. You'll need to take a hammer & punch & drive the shaft out of the rivet head.
Once that is done, grab you a drill with a 7/16 bit & drill out the rivet head.
Most of you can probably skip this step, but if you are among the lucky to still have Door Panel Moisture Vapor Barriers
its time to be careful! Slowly & carefully pull back the lower corner of the barrier so that you have enough room to see what you're doing & reach your hand in. If you happen to rip it, don't worry! We have replacements in stock & ready to ship. Check out the last paragraph for direct links to the parts.
Now reach in and grab hold of the Door Lock Actuator & lift it up to disengage the rod from the Door Latch. After the Door Lock Actuator is free, pull it on out in to the daylight & unplug it from its wiring connector. It's probably a good idea to go ahead & remove your rivet fragment from the bottom of the door at this time so you don't forget & end up with a strange rattle!
Pull out your new Door Lock Actuator & locate the short rod in the package. Slide it in to the collar & use a hammer to set the roll pin.
Because of the mass produced nature of these aftermarket Door Lock Actuators, sometimes a bit of casting flash is left behind from the manufacturing process. So grab one of your door lock actuator retaining rivets & see if it will slide freely in to the Door Lock Actuator retaining bracket. If not, grab your drill & a 1/4" drill bit & carefully remove the casting flash from the hole.
Take your new Door Lock Actuator back over to your Mustang & plug it in.
Engage the rod in the Door Latch & lower the actuator down in to position.
Slide the rivet through the hole & make sure that the actuator retaining bracket is firmly pressed against the door (this step is best performed with a helper). Using a Large Rivet Gun
, install the rivet.
Now test the operation of your new Mustang Door Lock Actuator. If your Mustang did not still have the Door Panel Moisture Vapor Barriers
, now is the time to install a set of our 50resto exclusive replacements as well as our exclusive Door Panel Sound Deadeners
to keep your Door Panels
dry & your interior quiet.
Once the big smile leaves your face, go ahead & put your Mustang
back together & keep on rocking in the free world!
