Have already got central locking installed. Seems that same switches are used to pass on the power. But don't know why autocop guys saying that it's not possible to install power window to sliding door. Will show them these switch images, and ask if they can install or not.
BTW, have you faced any maintainance issues with "power windows for sliding doors" as compared with "power widdows for front doors"?
