Hi

I have a Citroen Saxo X. On Saturday I went to open the driver's door,
and found that it now only opens half-way, i.e. reaches where the normal
"first point of resistance" is that keeps the door open, and will go no
further.

My first thought was that I'd been hit whilst parked, but I can see no
dents/scratches on the car. I can't see any physical blockage, and am
assuming it is something in the mechanism inside the door.

Has anyone heard of this happening before?
Does anyone have any idea what to have a look at?

Many thanks,
