The panoramic sunroof on my 2004 MCS
is sticking/juddering/having a hell of a time closing in particular.
It was a bit reluctant when I bought the car a week ago, so I smeared some multipurpose lithium grease on what I assumed to be the guiding tracks. That made it worse - loud and unpleasant juddering, and very slow to open/close - real strain on the motor.
Checked the messages here and it seems people have used white lithium grease, so I got some of that in a spray can. Just sprayed that arefully along the tracks and it doesn't seem any better - if anything, worse on closing, but a little better opening. I have to push up on the roof to get it to close, or the safety auto open mechanism kicks in.
I'm not sure I've correctly identified the bits that need lubricating - can anyone help?! I think I've only got a couple of tries left before the motor packs up...
