This is just a curiosity question. I just got my EXT about a month ago so I don't know alot about them yet. When I start it up and begin to drive, after about 20 feet or so I hear some kind of electrical motor noise for just a second. It's pretty loud. What is this?

I figured it was normal and had something to do with the suspension. I was just wondering what exactly it was. Thanks guys.

LOL, it's the ambient air sensor. It;s installed above your head in the headliner. I just had mine replaced under warranty.
