My sunroof opens fine but will not close. Appears to be an electrical problem -- bad switch or relay? Burnt out motor winding? Help!
I can crank it closed with the crank.

Have you tried to re-syncro the motor??

Put the roof in the vent (rear open) & then push UP on the switch for 5-6 seconds.

That happens to mine every so often - especially when the car "senses" an approaching rain storm... A quick re-sync does the trick.
