Remote Window ????How too??

You might be able to use the trunk button on the keyless entry (fob?)(but trunk wont open anymore with fob). Also they make relays that are timed/pulsed/constant you name it. If you want to try the fob, the brains are above the kickpanel on drivers side (i think). you would have to locate the trigger wire that pops the trunk, then disconnect it at the brains and splice it into the window switch asuming your switch has the "one touch" operation where it will roll down after you press the window button for a second. this would act like the trunk button would if you wired it to the "one touch" side of the switch. Also this will not roll the window up, just down. I have never tried this so don't get mad at me if it doesnt work, please! lol good luck
 
Many companies make modules that are designed to safely open / close power windows remotely. Most modules are designed for a pair of windows. They're fairly inexpensive, but rather complex to install - especially if you intend to add such to a factory keyless entry system. I don't know that you'd want the drivers' window to open fully if you pressed UNLOCK during a torrential down pour . . .

If your goal is simply to open / close the driver's window, then I would look into a garage door receiver, also offered by many security companies so that you can open your garage door from your aftermarket alarm remote control. These modules can have from one to three outputs that could be used to drive a pair of Bosch relays - one for UP and one for DOWN. Again, installation of such would be complex - seek out a qualified installer in your market.
