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
