Hi I have searched various threads but can't find any mention of this. The last time I tried opening the roof, i pulled the little lever to release the tonneau as usual, but it refuses to release open the right/passenger side. I assume something has come loose or broken, but I can't work out how to get at it! I presumable need to open the tonneau - but if I could do that there wouldn't be a problem! Any ideas on how to get the tonneau open without using the lever? Thanks
