Are you sure that the motors have had there day ? It could be the guide mechanism for the windows are warn / need adjusting . The drivers side is usually the worst for obvious reasons as they get the most use .

Many thanks - the chap restoring the car really is jolly good. He has used silicone and is of the view that the guide rails etc are ok- but the motors do not have the strength to push the window to the fully closed position- so the window stops short of being fully closed by about 1.5cms

That sounds more like the glass is binding on the rubber seals around the door / window surrounds and causing the window to run more slowly as it gets near to closed position causing the limit switch on the motors to activate . Also check the adjustable buffer pads inside the top of the door panel . They grip the glass against the external window seals to prevent the glass rattling . I had all these issues on my 1980 C3 on the drivers side . The passenger side ran as if brand new and still does .

A Haynes manual is available for the C3 which explains how to adjust the fore and aft and up and down adjustment to get the window winder guides just right to run true . You might pick up a reprint or old copy or find the info you need on internet . I dare say there will be a `how to` on Youtube as well .

I have just had another thought . It would be worth checking all the electrical connections associated with the motors too . C3`s are `live ` ( positive earth ) systems and good clean and tight earth ( ground) connections are vital to get full current connectivity .

I was going to say this too. My C3 had an issue where BOTH windows stopped working. Took the centre console apart and wiggled some wires and poked some plugs etc etc and they started working again. However, they have never been that fast in operation, but were faster for a bit after that. They've slowed again, so I need to take apart the console again and do a better job, and also do the connections in the doors etc.

The slightest resistance will have an effect an affect . Just look up Ohm`s Law .

Thanks to you all for your helpful comments

I will get to the bottom of the issue later this year- after waiting 2 years for the works to be completed I do not want to waste any of the Summer weather having the car back in the garage
