Question about Buick Regal
The quickest and easiest way to obtain a wiring diagram is to go to an auto parts store and buy a repair manual for your particular make and model. Look under the electronics section and it will tell you what the schematics are for your sunroof. The switch is a whole different problem, it may be easiest to obtain one from the dealer and replace it. You will not need the wiring diagram to accomplish this, a quick check can be done by removing the switch, unplugging the wires, and taking a short piece of wire which is bare on both ends and inserting it into the ground side and touch the other end to the hot side of the switch. If it activates then it is just a bad switch you can repair it simply by plugging the wires into the new switch.
