My near side window is dropping forward when being wound up leaving a gap at the bottom leading edge. The actual mechanism is fairly smooth and even whether winding up or down, it's just that the glass doesn't seem to want to sit level on its runner.

Is this a case of a new regulator, or can I get away with packing under the glass at the front edge to lift it slightly? Anything else I should be looking at? I haven't had the door card off to check it out yet as I want to wait until I get new window seals and do both jobs at the same time.

Probably the regulator is fine - the glass has probably come away from the rails. This would suggest rotten window runners / rails. Remove the door card and you should see enough of whats going on.

I had a similar problem.

Take the door cards off and investigate. I found on mine that the end of the runner was completely rusted away and the rubber was rotten so the glass had come out.

Depending on how bad yours is you may be able to re-align the glass in the runner.

Just had the door card off and the regulator off. Found that I've only got 1 glass channel on the bottom of the window, the one towards the rear!!!! I found the rubber for the missing channel in the bottom of the door, but no sign of the missing channel. Does the door glass come out of the door to fit the channels to it?

yes

turn the glass 90 degrees in the door then lift the glass up through the hole in the top of the door

Removal
1 Refer to Section 6, and remove the door interior trim panel.
2 Carefully ease off the waist rail finisher strips from the top of the door edge, taking care not to damage them as they are lifted away from the clips.
3 Wind the window approximately half-way down so that the two arms of the regulator mechanism are as near vertical as they can be. With a piece of wood, wedge the window glass at the sill in this position.
4 Remove the regulator mechanism securing screws (see illustration).
5 Pull the regulator away from the door panel enough to move it forwards so that the rear arm comes out of the window channel. Then move the mechanism back to release the arm from the front channel and lift it away.
6 Support the glass with one hand, remove the wedge and tilt the forward edge down into the door so that the top rear corner of the glass comes inside the top of the window frame. The glass can then be lifted out.

I did this yesterday to mine, replacing it is a pain... I found that fitting the rear runner to the arm, then sliding the front in and pushing the back of the window into the runner is the easiest way to get it back in

Took a fair few attempts :/ Good Luck!

Thanks for the tips guys. Got the job done today and what a complete PITA it was! I got the window out OK, fitted the new channel and rubber and then the fun began; every time i tried to refit the regulator it just didn't want to go on, forcing so much in the end that the channel kept coming off again. I must have had the window in and out at least 30 times!!

Eventually discovered that the regulator arms weren't in the right place relative to each other, so took it apart and realigned them by eye. Did this a few times until it all went back together nicely. This isn't a job I want to do again in a hurry!!
