How do you change windshield wipers on a 2006 Cadillac dts?

To change the windshield wipers on a 2006 Cadillac DTS, begin by lifting the wiper arms away from the windshield. Press the release tab on the wiper arm to detach the old wiper blade, then slide it off. Align the new wiper blade with the arm, ensure it clicks into place, and gently lower the wiper arm back onto the windshield. Repeat the process for the other wiper blade.
