WARNING: If your truck is under warranty do NOT do this, as it will VOID your warranty.
you will need a good day or two to do this job. as it can be a hassle.
You'll need to begin by opening the doors up. There are 2 screws holding each door panel on. (9/32 socket will remove them)
The first screw is located under the "control panel" (the part with your window controls/lock controls), you remove this part by lifting the smallest end straight up. once the clip releases, pull up and out to remove the other side.
The red reflector can be removed with a flat head screw driver.
Step 1: Once you have gotten the screws out
Step 2: Removing the door panel
Step 3: Getting the actuator out
with the door panel removed, you'll notice a plastic like sheet stuck to the door with stickem's, peel this off, and set it aside sticky side up. From there you will want to remove the outter door handle, 2 nuts hold this unit in (I belive they're 12 mm). the top one can be done with a ratchet, but the other one will require you to reach inside the door with a wrench.
