The sunroof on the 2009 clubman will not open I can get it to open if I help it but then it won't close with out me helping it. When you open it the back pain pops up then the front goes up and slides back. to get it to open or close I have to push up on the back half so it will open. The back half doesn't seem to move up anymore but it works if I do this. I tried to clean the tracks and put some white grease on it but still the same. I don't know if I should take the glass out so I can get it cleaner or if there is an another fix. Has anyone dealt with this problem?
