Note in the first pic the metal shield. Remove this.


Now you can see why your motor spins, but nothing happens. The black pressure disk is eroded and no longer pushes pressure on the pink clutch area. this clutch system is to keep your motor from overstressing when it reaches the top or bottom.


Now we clean the unit up and start to do the repair. What you need to do is find a way to lock the pink slipper disk to the inside black disk so the motor spins the clutch again and the outside gear moves. This will solve your problem with the motor working, but not turning the gear. with both units locked together, they motor will have a direct drive to the gear and work properly again.

the object here is to lock the base of the gear you see in black to the black disk it sits on. Normally the gears base would have the black pressure disk attached, but it is eroded.

I will post a pic later of how i lock the units together once i m done.


Since we do not have a slipper clutch anymore, we do not need the rubber disk the gear base sits on. so let's just remove it.


The "correct" way to do this is to remove the c-clip on the top of the gear and the two metal washers. then simply slide the gear off and remove the rubber slipper material.

from here, clean the unit very well.


now just slide the pink spur gear out and get to cleaning.


Now after some heavy duty cleanup with comet cleanser (cut's oil and grease) i am ready to get the repair started with my clean surfaces.

You can use a million different epoxy's, glues, and so forth. I have chosen to use my tried and trusty Liquid Nails. After it hardens in 49 hours it should be as solid as a rock.


and................ we're done now... let's go grab a beer and wait for 48 hours to reassemble.

    ... it halfway up out of the door. Check to make sure that the glass is sitting in the front and rear glass channels. If it is not, tilt the front edge of the glass down in to the door to get the front and rear properly seated in to the channels. You should be able to push the door glass up and down smoothly.

    ... When the glass falls forwards it is likely to fall out of the guide channel as well so you need to check this before you re-attach the clip. Once you have made sure the glass is sitting correctly in the guide push the ''ball'' of the control arm into the ''socket'' of the new white plastic clip. Next is the hard bit which is keeping the ball pressed into the socket whilst sliding the ... (more)
