Don't bother
I purchased one of these and had some problems with it.  First, it is extremely easy to install, if you have hand cranked windows.  Don't try to put it in an "auto-up" window as the sensor will reverse the window back down as soon as there is any resistence.  I tried it in a rear door window and could never stop the window at the exact correct position to have a good fit.  It either stopped short or it went up far enough to crack the device.  After repairing the housing twice, I got it in, but unless the car was parked with that side facing directly South, the little fan would not turn.  I live in Alquerque, so not having enough sun was not the issue.<br /><br />This unit is too under powered and too flimsy.
