The arms on my rear roller shade are up and the roller shade is down (arms disconnected from shade). So, I finally purchased the Bentley Publishers 2 volume service manuals only to find that the rear roller sun shade is not covered. Anybody have any detailed instruction on how to repair? The motor and arms work just disconnected from the shade and the shade is down preventing the arms from lowering. Did I miss it the manual?? Can't believe its not included. Any help would be greatly appreciated.
