Evening people...

Ive been hit with the age old window problem...

The window goes down, but doesn't go up...... After a bit of research I bought a Window Mechanism motor assembly, so I bought one off ebay.... Lucky me I thought!!!!

Needless to say, now ive come to fit it, or should I say a friend has, its actually the slider part I need as where it attaches to the assembly its actually broken the plastic clip, hence why it doens't go up, just down......
Can I get just a slider? or should the whole thing come as a complete unit?
Im puzzled....

Many thanks
Tristan
