The wife's citroen c3 pluriel

[vmax1974]

The wife has one of them c3 pluriel's and the rear side window keeps falling down in its frame
Now I am sure its just the regulator but I am having difficulties getting at it without damaging the trim does anyone know how to get the n/s rear side trim off without damaging it

Its made of that god awful hard cheap plastic and will surely cost a fortune if I start pulling at it

Does anyone know any suppliers I can get the repair parts from

Please someone help cause the wife will be very happy with me if I can fix it

Thanks

Dave
