I've taken the cover off the back where the runner is and cleared out the muck and greased it all up, but still no joy. However I noticed that there is a hook type catch in the rear mechanism that doesnt stay hooked round anything when its shut and there is a clear gap of a couple of cm.
Anyone got any idea if this should stay hooked round the metal and if there should or shouldnt be a gap - as it looks like this gap is whats creating the gap on the left!?! Any help much appreciated. Ive take some pics to show what I mean.
-If anyone has a pic of their door shut showing the rear mechanism that would be useful to compare.
