Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.

In this video, we are going to show you how to replace the rear door lock actuator on this 2005 Ford F150. It's the same parts and process on this F150s from 2004 to 2008. We show you on the driver side, but the passenger side is the same procedure. The items that you'll need for this include a new rear door lock actuator from 1AAuto.com, a 6mm, 8mm and 10mm socket & ratchet with an extension, flat blade screwdriver, T25 Torx bit, and a 5.5mm socket or 7/32" socket.

Pry out on the small panel behind the door handle. Then pry up on this panel, and just pull it forward. Lift it up and push the tab on the harness and disconnect it. Then pull out on this panel and pull it free. It helps to use the flat blade screwdriver and just pry it free. Remove the 6mm bolt, these two 8mm bolts, this 10mm bolt, and then these two 6mm bolts down here. We'll fast-forward as Mike does that. Now lift the door panel up and pull it out. Then you want to pull out your door handle cable. It's easiest with a flat blade screwdriver to pry it out. Then unclip it from the door handle, and your door handle's free. Then remove these 5.5mm or 7/32 bolts from your speaker. You may notice that we switched doors. We're just going to show you the procedure on this door that actually has a water shield. Pull your speaker out, and then just push the tab on the harness and disconnect it. Then just peel back your water shield. Then you want to do this slowly so as not to rip your water shield or stretch it too much.

Now remove this 10mm bolt and just pull that bracket out. Now reach back here, and with a flat blade screwdriver you want to just pry the screen clip open and pull the rod out. Now remove these three T25 Torx screws, and we'll just fast-forward as Mike does that. Now you want to just pull these clips out, just push the tabs on the back and pull them free. You just reach in and try to squeeze the tabs together on the backside and pull. Now just work your door lock actuator assembly down and out. It does take some maneuvering to get it to come out but just keep working at it and will come. Push in on the tabs on this harnesses and disconnect them.

Now, using a flat blade screwdriver, just pry down on the tab underneath the door lock actuator and slide the actuator off those rails.

On the bottom is the old door lock actuator; above it is the new one from 1AAuto. You can see they are identical and they'll fit exactly the same. This part locks in, so you may just want to kind a flex it out a little bit, slide it down into place, make sure that your arm is going in there and lock it in.

Reconnect the harnesses. Make sure they are connected all the way, and then feed the door latch assembly back into the door. Make sure you push the lock rod up through the door and to help hold the latch assembly into place. You just clip on the child lock into the door and replace one of those T25 screws just preliminary right now to hold it in place. Make sure you push those yellow clips on the cable back in. Replace and tighten up those three T25 screws. Now just put the door handle rod back into that green clip and re-clip it. Then take this bracket, put it back into place, and replace and tighten up that 10mm bolt.

Now replace your water shield. Reconnect your speaker. Push it back into place and then replace those four 5.5mm bolts and tighten them up. To replace your door panel, just re-clip the door handle cable into the door handle and then push it back into place. Make sure these clips stay into the door. Then line up the tabs on the back and make sure that the lock rod goes up through the door panel and that your harness for your window switch is coming up through that hole in the door panel. Then push the door panel down into place. We'll fast-forward as Mike replaces all of those bolts. Now replace the small panel behind the door handle, reconnect your window switch, push those tabs into place, and push the panel back down. Then line this panel up, slide it down into the door panel, and push those two clips back into place. You're all set.
