[V8] V8 Sunroof Problem

[dsaad at icehouse.net]

Look at group 60 in the manual. It has pretty specific instructions for testing
the sunroof stuff.
On the electrical diagrams, spend some time looking at the first few pages -
this explains how the schematics work. Once you get the hang of it, you can
trace through circuits pretty quickly.
