'morning folks, hope this finds you all well?

You may have noticed I posted in the "not grumpy but not smile" thread that I did a big service and front pads/discs on my daughter in law's Jazz on Friday. During the test drive I always test all the "wee" things like window winders and all the other controls.

Usually the test drive, on any of the "family fleet" goes without incident and I get considerable pleasure from enjoying the car, for a half hour or so, running just as it should. I like to drive with the driver's and passenger's windows down for some of the time when possible - you can listen for "outside noises" better that way. It ran beautifully and I was feeling very pleased with myself until I came to wind the driver's door window back up again when I stopped out side my house. It was triggering the anti-trap just before it closed fully. My daughter in law said, "Oh, it's been doing that for a while". I will refrain from appropriate comments! She went on to say "but it's Ok because if someone pushes it in from the outside as you raise it then it goes all the way up".

I was worried that it might be something internally to do with the electric winding mechanism - not the sort of thing which is usually easily fixed, often causing bleeding knuckles! So I was almost glad to see that the rear glass guide was showing a "polished" wear indication at almost exactly the point where the window was triggering the emergency stop.

I gave it a good spray of silicon oil and, thank goodness, it's now working absolutely fine with the motor sounding much less strained. I then went round and tried the other 3. The O/S rear sounded "bitty" by which I mean it was smooth in parts but you could hear the motor working hard at one point in particular. So I sprayed all the glass guides on the car and they are all now "as smooth as silk".

So now to why I'm mentioning this. I've used silicone oil for lubing window guides for many years and, being non greasy, I find it works well. The only criticism I could level at it is that it tends to need re-treatment quite often to stay effective. Anyone found something better for this job?
 
The guides are usually rubber with a felt covering. Once they start to stick, it is usually a sign of the felt having worn through. The shiny bit you can see is probably polished rubber, doing its best to grip the window. So any lubrication will need regular reapplication. New guides are probably horrendously expensive, and will require lots of special mechanics language while fitting.

The guide rails in the door, which are slightly adjustable may have a role here. If the window tries to tilt near the top of its travel, it will wear the guide more quickly.

Good luck, I've always hated fiddling inside doors. Blood will be spilt.

See if these guys have anything suitable. https://www.woolies-trim.co.uk/category/341/single-track

Thanks PB. Yes I can see that "shiny" bit quite clearly so I'm sure your diagnosis is correct. She's had this one for quite some time now and although it's mechanically basically sound it's looking a bit "ratty" round the edges (12 years old now) and I know she's been thinking of replacing it. So I think a couple of tins of silicon spray will be the best investment. With a bit of luck it'll be replaced before the window packs up, like you I hate fiddling around with window winders but also those "silly" wires - and there's usually quite a bundle of them these days - which carry power to the door internals and often suffer cracked insulation or actual breaks where they transition from the body to the door. Surely someone can think of a better way to do it than simply flexing the wires?
