Thank you for the advice on how to close my roof when it failed open. I am almost there. I cant slide one of the hooks forward to lock down the hinge. Refereing to the Owners Manual page 10 - 31, illustartions 14 and 15, pdf page 147 of 206 tells you how to reset the hinges. Whilst pusing down on the hinge you push forward the hook to lock the hinge. The manual suggests using the jacking handle. On the offside I can push forward the hook just with hand pressure. On the nearside the hook and hence the white block it sits on wont move. I have used a level of force but with no joy. I have unlocked the offside and tried the nearside first but no joy.Before I dismantle the whole assembly does anybody have any suggestions? Thank you. Paul.
