Its not the switch, Its the controls on the motor. With that said, Yes some one a while back did modify the window.
Also just a word of caution, when you do that you disable the safety and if some one is in the window opening you can seriously injure them. ( Disclaimer... )
I agree with Todd. If you have dogs in the truck and modify that window you might injure them. I know I have to watch mine when closing that window. Good idea but I think dangerous once you look at the risk.
