window stuck in the up position

[mpbarrett]

On my 13/60 convertible the near side window is stuck in the up position. 
tried moving the glass but it is very tight and the winder mechanism is stuck solid. 
Cant see what's causing the problem and not sure I can get the mechanism out without lowering the window.

Any suggestions what's jamming it?

cheers

When you say you can't see, does this mean you've removed the trim panel from the inside? Get a small mirror, rear-view mirror sized, and have a look inside the door through the large cutouts in the door frame - you may be able to spot what's jamming it. I've found that any wear in any of the components leads to an alarming amount of movement and in the tight confines of a door, things can hit off each other as they pass.

yes panel off and had a look but cant see anything obvious thats causing it to jam, but will get in with a mirror tomorrow to have a closer look.

Is there any movement at all? Slight rocking of the lever back and forth may highlight what's sticking; otherwise work along the arms of the winder system and see if one has jumped behind the quarterlight frame, or any other of the door's internals, and is stuck there. Be careful of the sharp edges; after last week's work on my door I looked like I'd been self-harming.

no movement of the winder or window, stuck fast. All a bit strange, will get in with a mirror to try to see whats happened!

get the sticky plasters at the ready 

the central pivot pin of the scissor levers has an eccentric adjustment by rotating it 

lots or wear and tear bits in these crude mechanisms rollers popped out of the rail  etc.

On my car, when delivered as found, somebody had unbolted the glass runners and the glass was displaced entirely and jammed. Took two of us a whole day to assemble it properly due to seized bolts etc. It's all ok now.
