Watch out, there are two control modules - one supplies power to the 
sunroof and windows from key-on to door-open.  The other provides the 
one-touch-down feature on the drivers window.

It's either going to be that first unit, or a wire problem in the door 
jamb (but does sunroof power go in and out of the driver's door?  I 
don't think so...)

Even if it is the control module, I'd pull back the door boot anyway 
just for a look-see.
