First off, you have a Gen 2 RR or P38...it's the next forum down from this one.

RR classics stop at 1995.
Second, Go here for a free manual download:
The Green Oval - Downloads | Land Rover Data
You need CD #2
Third, regarding your window...I'd look at the areas that were messed with by the punk that tried to break in...sounds like possibly a wiring issue, fuse, etc. Do you have power to the switch?...to the window motor?
