In this video, we're going to show you how to remove your cowl cover, or air grille, on this 2006 Cadillac CTS. Here are the items you'll need for this repair: 15mm socket and ratchet.

Remove the black caps on the windshield wiper arms. All you have to do is squeeze them together and pop them off. We're going to use a small piece of painter’s tape. Sure you use the straight edge to mark the position and angle of the wiper blade so we can reinstall our wiper arms properly. Remove the two 15 millimeter nuts securing the wiper arms down with a the 15 millimeter sock and ratchet. If you're only replacing one arm, you'll only have to do this for that particular one. Work the wiper arms off of the splines. Do this by grabbing them at the joint. Simply pulling up and pushing down. Eventually, it'll work its way off the splines, and you can remove your wiper arm.

Line up your wiper to the tape mark we made on the windshield earlier. Torque to 26 foot-pounds. Line up your wiper to the tape mark we made earlier. Start the nut by hand. Torque the nut to 26 foot-pounds. Reinstall the plastic cap. Close the hood. Remove the tape marks from the windshield. Check for proper operation of your wiper motor.
