Noise after turning car off and opening door

[Cypress]

Hi all,

I am new to this forum and have already got some GREAT info. I just picked up my Touring Sport with Nav on Saturday. It's hard to say exactly what I paid for it because of my trade, but let's put it this way... I started off on the phone with $38600, but then the dealer gave me $1500 MORE for my trade than CarMax wanted to give (and what KBB suggested). The car also had a very small ding in the fender that they fixed with PRD. I ended up getting another $1000 off. So one number I can give you is $37600. Another number considering I got $1500 more for my trade is $36100. Anyway, I know this is not the price forum, but this is my first forum and I just wanted to give that short intro.

So here is my question. After I driver the car, and I turn it off, almost exactly (actually slightly after) I open the door (and it can be either the driver or passenger door), I hear a noise. I can best describe the noise and an electronic motor whirring for about 1 second. The noise comes from the left side of the driver cluster.

Is this normal? Anyone know what this is?

P.S. You guys have already helped me with another problem that is not documented and that is how to get video to play form the video inputs in the console. Apparently the E brake has to be engaged. So, I know you guys are the best, I look forward to a quick response.
