Folks, as of yesterday when i attempted to rolled down the front passenger window from the main controller on the driver side, the button for the passenger window shatter into two, now i am unable to utilize the passenger window from my end and now i am left with a hole on the main window controller.

I would like to know if i need to replace the entire window controller switch or just the section that is broken. Also, where on the web can i purchase this part.

Thanks.
