Hi,

This sounds like either the door module has failed. Does the window or lock work from any switch for the window? Meaning the driver should have a master switch that controls all windows. Does it work the passenger side window or lock?

If not, the door module is most likely your issue because this controls both the window and the locks.

The best way to check this is to hook up a scan tool and try to operate the window and lock. If it works, you are basically taking the place of the module so that confirms it is the issue. Also, you can monitor the button input and see if the module even sees it. My guess is it will but is not sending the signal.

Let me know if this makes sense and we can go from there.
