Adjusting the Door Glass to get a good seal

One of the areas that seem to cause more problems than any other is that of the getting the door window glass to seal properly and prevent leaks. Whilst the Workshop Manual gives step by step instructions (see PDF files below) on how to adjust the glass, it fails to emphasize several of the more significant points.

Glass Retention Assembly

There seems to be some confusion over how this assembly fits in the door ( least I was initially!). If you look at how the manual displays it and labels bolts H and G, then look at how mine was assembled in the car, then bolt H sits below G in my left-hand door. The Retainer body of mine is clearly marked with an 'L' (left-hand?) so I assume it is fitted correctly.

The assembly is made up of several items, with the main retainer body and blue plastic adjuster having circular mating serrations. Adjusting these two either vertically up or down changes the pre-load angle. When the plastic adjuster is lower than the main body, the top edge of the door glass is moved in towards the centre of the car, increasing the pre-load on the seals. Moving the plastic adjuster upwards relative to the main body moves the glass away.
