In this video, we're going to show you how to remove your cowl cover or air grill on this 2006 Cadillac CTS. Here are the items you'll need for this repair: 7mm, 10mm, 15mm sockets, ratchet, socket extension, torque wrench, and painter’s tape.

Remove the black caps over the nuts for the windshield wiper arms. All you have to do is squeeze them together. Pop them off. We're going to use a small piece of painter's tape. You should 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 15 millimeter socket and ratchet. 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.

Peel off the leather strip. Move these four 7 millimeter screws. We're going to use a 7 millimeter socket and ratchet. Lift up, carefully release this plastic, as it's hooked under the windshield. See the little hooks here, just be careful to pull out and away with those. Remove this 10 millimeter nut up against the fender on the driver's side. Lift up off of the splines for the wiper arms. Remove the driver's side of the cowl cover.

Reinstall the driver's side of the cowl cover first. Be sure that all the plastic hooks line up under the windshield. Reinstall the 10 millimeter nut. Reinstall the passenger side of the cowl cover. Again, make sure that all these hooks line up and go underneath the windshield. Reinstall your 7 millimeter screws. Reinstall the rubber seal, the channel simply presses onto this ridge here.

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.
