Middle seat, won't fold
 

Hi folks as above really. The middle back seat won't fold. I've slid it all the way back, all the way forward, jiggled it about, swore at it, everything but it refuses to fold.
Thinking that the cable operated by the wee lever is maybe stretched so I'll see if I can get some vice-grips on the square bar at the bottom to see if it just needs to turn more...

Sussed it out. The wee square bar had wandered out of the left hand side. A wee wiggle and it was fixed.

Good. Well done!
