In this video we're going to be working with our 2006 Chrysler 300. We're going to show you how to remove and replace your vehicle's wiper motor or transmission. This process is the same regardless of which one you're changing. It's just going to be a matter of which new part you bolt the old part to.

Here are the items you'll need for this repair: trim removal tools, painters tape, flat blade screwdriver, 8-15mm sockets, ratchet, socket extension, swivel, phillips screwdriver

Before removing your wiper arm, use a small piece of tape on your windshield. I like to use painter's tape. Mark the edge and the angle of your wiper blade, so when we reinstall the arm we can make sure it's in about the same place.

Take a small flat blade screwdriver and pop the cap off the end of your wiper arm and remove the nut. Using a 15 millimeter socket and ratchet, loosen and remove the nut on the end of your wiper arm. Once the nut is out, push down on the joint of the arm to loosen it from the splines and remove it. Repeat these steps with the opposite wiper arm.

Using a trim removal tool, remove the nine push pins securing the cowl to the cross member going all the way across and in the same place as on the opposite side. In each corner there's a Phillips head screw and a little plastic pin on this rubber piece here. We'll have to pop the rubber off of that pin. It pops off by hand. Remove the Phillips head screw. These screws only need to be turned a quarter turn counterclockwise to release the hooks. If yours strip, you can reach underneath and move the hook by hand. The rest of the cowl is held in with metal clips under the windshield, which simply pull up to release so you can remove your cowl cover.

Disconnect the electrical connector from the motor. Remove the two 10 millimeter bolts securing the wiper transmission to the vehicle. We'll do this using a 10 millimeter socket ratchet and extension. Remove the assembly from the vehicle.

Now the procedure for changing your wiper motor or the transmission is going to be the same because these parts are available separately and you'll need to separate the two and attach one to the other depending on which you're changing. Either way we'll use a T30 torque socket and ratchet to remove the two T30 screws attaching our motor to our transmission. Be careful for the captured nuts inside the bottom of the motor. Those can fall out. Lay the motor over and simply pop the linkages off of your motor.

Now in our case we're changing the wiper transmission so we'll slide the two captured nuts back into their slots on the motor here and install our new wiper transmission.Now we'll take the driver's side linkage and pop it onto the second ball on the end of the wiper motor. We'll pop the top on as well. Set the alignment pins to the inner holes on the wiper transmission and install the bolts into the motor. We'll then reinstall them with our T30 torque socket and ratchet.

Reinstall the wiper motor and transmission assembly and start your two 10-millimeter bolts by hand, one on each end. We'll then tighten them down with a 10-millimeter socket ratchet and extension. Reconnect the connector to the wiper motor.

Reinstall the cowl cover. Line up the metal tabs on the windshield side, snap those into place. Reinstall the hooks. If your Phillips head screws didn't round off like ours did, you can turn them with a screwdriver. However, ours are stripped, so I have to reach underneath, and turn the hook by hand, and slide the rubber under and lock it back over its tab. Reinstall any of the nine plastic clips you have. Don't worry if you're missing one or two. Ours is as well.

Reinstall your wiper arms. They are different. The one with the shorter leg here where the hinge is goes on the passenger side. Line it up to the tape mark you made. Reinstall the 15-millimeter nut. Hold it in place and use your 15-millimeter socket and ratchet to tighten it back onto the splines. Reinstall the caps on the ends of the wiper arms. Remove your tape from your windshield.
