The driver's door window won't operate. How do I find proper repair instructions on 2004 Chevrolet Suburban 1500

How do I step by step pull of the panel, disconnect the electric buttons and perform diagnostic and repair?

first of all I would check the wirng harness between the door and the body if there are no broken wires then you just have to pop the the switch out and see if you got power and ground there
