E46 Convertible Rear (door) Cards

Hi all, I'm new!

Just bought a 55 plate / 2005 e46 M3 and the windows travel fairly slowly and at different rates. sometimes they'll bounce down again. I'm convinced that the rear window mechanisms channel require greasing (as after siliconing the guide slots, there was little improvement).

Is there a guide as to how to remove the rear cards to expose the rear window mechanism (I would say door cards - but it's a convertible!!)

Apologies if there's already a thread on this but I couldn't find it when I searched

Cheers

I havent done it but there are adjustments to the windows that adjust the angles(in/out, forwards/backwards, and possibly overall height).

The fronts are behind the outer door molding, not sure where the rears are.
