Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of Thanks.

In this video, we're going to show you how to replace a wiper arm on this 2005 Cadillac CTS. The only tool you'll need is a 15mm socket and ratchet.

At the bottom of your wiper arm, there's a small black cap. You want to just pry this right off and then remove the 15mm nut underneath it. Push down and pull up on the wiper arm until it pulls free. Put the wiper blade back and there's a tab right here. Just push that in and slide your wiper blade off and then slide it on to your new wiper arm. Pull up to lock it. Put your new wiper arm into place. Replace that 15mm nut. Tighten that up. Replace that cap and you're all set.
