Hi m8,
Ive got the same problem.Your motor chatters when trying to lift the roof right?
The only solution is to replace the whole motor with a used 1 or have it overhauled by SIMPLY SAAB from Bristol (see ebay-tonneau motor).Used motor around £125.Re-con £300.Once refitted it WILL have to then be taken to saab for re-timing.This MUST be done or you will damage your car...Trust me on this 1 fella!
