If the windows are working, that takes the timed relay out of the equation.

I believe the roof has its own little circuit breaker (silver, about 1/4 
by 3/4 by 1") in the auz relay panel.

There is also a relay, under the cover that holds the switch, and some 
microswitches that tell the relay which motors to use.
