There is a friction clutch between the motor and the cable to stop it stripping the gears at the end of travel when retracting the lifting arms (there is no limit switch to stop the motor). Perhaps the grease has got into it and now it's letting go too soon? There is a guide on Clarks garage that tells you how to adjust the slipping torque correctly.
 
As many of you will know, my car has be in and out of JMG in Christrcurch for the last 2 years, and I've asked them to attend to the sunroof over and over again. And it still doesn't work. Lots of mutterings about looking at wiring diagrams and microswitches, but no actual fix. Must be harder than it looks...
 
my sunroof will go up and down manually so i dont think anything is slipping. Ewan,that doesen't inspire me with confidence! [:D] would be nice to get it sorted but can live without it. good luck with yours !
 
How do you go about getting rid of the sunroof altogether? I understand that it can be welded up? for racing purposes? Is this true? I would like to get rid of mine. The seal around the outside keeps going Green and i keep cleaning it of again. The car is due for a respray soon so if any welding is to be done, now's the time.

When you turn the nut, it is outboard of the clutch, so if the clutch is slipping the manual operation will still work. From my experience, the factory setting is in my opinion too stiff. It is OK when the car is new as both arms reach their end stops together, but if one gets to the end first it WILL strip followed by the other one stripping in sympathy a microsecond later. I backed off the clutch setting until it just drives the roof and also fitted spacers under the sockets in the roof itself so the arms move freely into place. Also make sure the roof settles down flush with the body particularly if a new seal has been fitted and not fully tapped into place.
 
ORIGINAL: Veerzigzag I forgot to mention Rule 1: Check Clark's Garage. There is a good procedure about sunroof gear replacement.

You can't weld in the existing sunroof because it's plastic. Best thing is to bond in a carbon fibre or GRP panel like this: https://www.gt-racing.com/products-page/924944951-parts/944-sun-roof/ Obviously you will also need a new headlining (for a road car).
