Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace the blower motor resistor on this 2006 Jeep Liberty. The only items that you're going to need include a 90-degree pick, an 8mm socket, and a ratchet.
Start off by opening your glove box. Push in on the sides, and then pull the glove box down. Your blower motor resistor is located right here. Using a 90-degree pick, pry the red clip underneath the harness out, push the tab on the harness, and pull it free. Next, remove these two 8mm bolts. We'll just fast-forward as Don does this. Now, the blower motor resistor will pull out.
Push your new blower motor resister into place and replace those two 8mm bolts. Then just tighten them up with the ratchet. Reconnect your harness, and then push that red clip in to lock it. Then push your glove box back up into place.
We hope this video helps you out. Brought to you by www.1AAuto.com, your source for quality replacement parts and the best service on the Internet. Please feel free to call us toll-free, 888-844-3393. We're the company that's here for you on the Internet and in person.

Works great! Easy install with the aid of 1A Autos video and was a good daddy daughter project.
so far , so good
My ac on my Liberty would not blow in speed 1. After ordering and receiving the blower motor resistor, I watched the 1A Auto video on installing it, and easily installed it. It fixed the issue and the ac blows in all speeds.
I have used 1A Auto for various components over the years with no issues and this item was no exception and it fit perfectly. It was just like the original. The 'how to' videos are excellent for the 'do it yourselfer'. Also I received this item in a timely fashion.
Easy to order, received it quickly. Completely satisfied
It work very good. Thanks Very much. It was on time and easy to keep track of shipping. Love it.??????
