Good Evening

I have recently bought a mark 3 escort 1.6 ghia, nostalgia bit me!

However, after my stoooopid son fiddled with the sunroof I now seem to have developed a leak and windrush noise, I cant get it to 'close' properly as the winder mech seem to be broken and just goes round and round doing nothing

So, if I cant open the sunroof how can I repair it? Is this a garage job....

Hope someone can help
