Well I dug out my multimeter to do a few voltage checks. There was no additional fuse to the motor assembly. The clicks were the relays which control the direction and speed control for the main drive etc. The problem here was the black round flap which covers the hole for the allen key drive to manually turn the motor to enable the roof to be manually closed. This flap operates a separate set of contacts isolating the motor armature to prevent injury should the motor turn whilst the allen key is used. The flap should be in the home position (hole covered) to allow the motor to operate. In this instance the contacts were permanently open even when the cover was in the right place. What initially happened was the rivets that connected to the pins that operate the front flap to the sunroof had snapped causing the main roof to collide with the flap and the motor had laboured. The excessive force caused the contact cover to turn slightly which then kept the contacts open! At this precise time fuse 21 blew which removed power to the radio and the sunroof. After removing the cover to the gears the contacts sprung back to the correct position. I wonder how many people have had to pay for a new motor when a simple strip down was needed to refit the contact cover!!! The front flap has been temporarily been fixed in the down position to enable the roof to move freely.
