Use some small pieces of painters tape to make a straight line with your wiper blade. This will help us position the arms back on without needing to do trial and error. Using the flat blade screwdriver, pry out on the tab on the top edge of the wiper arm at the pivot. Remove the wiper arm from the pivot. Do the same thing on the opposite side.

Remove the weather strip from the top of the firewall. Remove the three Phillips-head screws securing the cowl to the truck on both sides. There's one down on this opening. There are three, both in the same positions on either side of the vehicle. Once you get the first three screws removed, lift up and remove this corner panel that goes around the hinge. There's a fourth Phillips-head screw under there you'll also need to remove. Remove the three screws from each corner of your cowl.

Once that's done, you can remove all four of the Phillips-head screws along the front of the cowl. Pull back and lift up to remove the cowl. You'll need to disconnect the washer hose over here on the driver's side. Remove the cowl from the vehicle.

Loosen the 10 millimeter nuts on the wiper linkage. There's no need to remove these entirely. If you're doing the driver’s side arm, you can stop here and move on to removing the other portion on the other end of the arm. However, for the passenger side, you'll need to loosen this.

Remove the blue safety tab in the connector by pulling it straight back. Lift up on the tab with a small flat blade screwdriver and remove the electrical connector. Then remove the three 10 millimeter bolts around the body of the motor with a 10 millimeter socket ratchet and extension. Once the screws are out, wiggle the motor to release it and then you want to pull back at the driver side, slide it out until the center of the pivot ball is in the center of the opening, and then pull out to release it.

Reinstall the wiper motor by sliding the arm back through in the opposite fashion you used to remove it. Start one of your 10 millimeter bolts to keep it in place. Get the other two going, reinstall them with your 10 millimeter socket ratchet and extension. Reinstall the electrical connector and snap the blue safety tab back into its loop. Snap the arms back on to the wiper, tighten them back down with your 10 millimeter socket and ratchet. Make sure they're in the same place they were removed from.

Reconnect your windshield washer hose, and lay the cowl back into place. Reinstall the four screws in the center section of the cowl. Reinstall the two short screws on the end. Once the rear one's in, you can reinstall the plastic cover. It simply slides in and drops down. Reinstall the longer screw on the outer edge here. Repeat these steps on the opposite side. Reinstall the weather strip onto the top edge of the cowl.

Now, I know we had mentioned using the painters tape to align these earlier, but it turns out these wipers are keyed, which means they'll only go on one way. Simply pull out the tab and slide them back on. Lock the tab back into place. Lay the wiper down. Remove the tape.
