Window -Winding Problem

The manual windows on my 1986 car have been getting stiff for a while, and last week the drivers side jammed open. The bottom of the glass is held in the window winding mechanism by a silicone rubber sealant which tore free, causing the glass to drop out of the guides. I can put it back but if i wind the window down more tha about a quarter it jams on the way back up

As you wind the window further down, it pulls further away from the winder mechanism at the back, and moves out of the slider channel at the front.

I have actually bought very strong sticky black silicone rubber sealant here in the past, that might do the job, but I can't remember what brand it was, and probably wont be able to buy the same stuff again. I have some red automotive RTV that I could try but it doesn't seem to have as much tensile strength, so will probably not stay in.

It might try tying some fishing line across the top of the glass to help pull it down and take some of the strain off the sealant, though it may not be possible to feed past the bottom window seal.

Duct tape/Duck tape over the silicone might also help

I can lubricate at least part of the wiper mechanism with chassis grease, silicone grease, or anti-seize, and it might take some of the strain off the winder handle (these are getting brittle and will be hard to replace) but wont affect the tensile stress on the sealant, so wont stop the glass pulling out of the bracket.

To do that, it might help more to lubricate the window guide channels, but I'm not sure what to use. I'm thinking maybe silicone grease, a wax, or a soap. Somethimg like graphite powder or a Teflon-based grease might be better but I can't remember seeing either of them for sale here. Perhaps working some teflon plumbers tape into the guide would help, though it wouldn't be likely to stay in place for long.

Any suggestions?

There must be industrial adhesives that would hold the glass in the channel, might be worth contacting 'EvoStik' or similar'? A hot- melt glue gun might do the trick too.

Years ago I had a window broken on one of my bangers and having a sheet of 4 or 5 mm thick acrylic, I cut that to shape and it served for months till I had time to trawl scrapyards for a replacement glass.

I looked at a Mini Marcos (which I REALLY regret not buying) that had acrylic windows with a sort of stick ratchet thing for pushing them up and down, so I suppose at the worst I could fit something like that, if I hide it for inspection.

Apparently the recomended goop is this stuff, 3M 08641

They won't ship to Taiwan, though, as is usual with this kind of thing.

maybe some fish tank glue (the type that holds the glass together)

maybe make the glue contact area bigger

or mebbe glass clamps that you see holding shop windows
www.ebay.co.uk/itm/1-4X-Stainless-Steel-Glass-Clam...A

maybe drilling a hole in the bottom & a rubber grommit..

To keep the pane in the groves, maybe a "U" clip plastic, to stop the glass from wiggling at the bottom...since once it's in the tracks, I'd imagine it would be ok.

I had this happen on our L200 truck.

I took it all apart, glass out, regulator out and cleaned the glass, the folded steel channel that holds the bottom of the glass and the rubber that clamps the glass with thinners.

Let it all dry and then used instant Loctite to assemble it all back together, the channel and rubber has to be thumped back on to the glass with a rubber hammer with the Loctite applied to the rubber to bond to the glass.

All this is caused by the glass binding in the runners, I now use silicone oil spray down the runners once a year, preferably with the sort of extension spout you get with a WD40 can so it gets to where it is needed and not on the trim or body.

Looking at your pics, it looks like the metal channel that clamps the glass needs closing up a bit to grip the glass via the rubber a bit tighter.

I cleaned it up a bit, sprayed WD40 around, rubbed down the rust in the C-channel of the winder, greased it with EP lithium grease and put silicon grease in the window sliders (rather sparingly, since I dunno where to get it locally)

[url=servimg.com/view/18149521/249][img]i58.servimg.com/u/f58/18/14/95/21/th/img_7413.jpg[/img][/url]

Didn't take the winder apart, since I couldn't get a socket on the recessed glass bracket screws and they weren't coming out with a screwdriver, though I suppose I might have tried harder if I had thought taking it out would do any good.

Seems to move a bit better but the glass still goes out of alignment, unsurprising since its only attached at the front.

If the glass-sticking goo is unobtainium locally I might try contact adhesive and seatbelt webbing, which should give some flexibility. I understand some cars have alignment aid "buttons" to guide the glass into the groove, so I might try and improvise something like that, either outside or inside. Meanwhile I'll have to limit it to less than half open.

Since I might not take it apart anytime soon I may put spray grease on it.

I've got some "3M Silicone lubricant (Dry Type)". Not sure if it has a solvent carrier or not.

How about that for the window sliders?

Aquarium adhesive probably is available here since its a popular hobby, though I dunno if it'd be strong enough.

I did have some Loctite but it was quite hard to get and I lost it when the university threw away the fridge I was keeping it in.

Ordinary cyanoacrylate superglue (which I think is similar) might be worth a try.

Used to have to do the same on the old Rovers apart from the glass mounting was bonded to the glass, good clean off and loctite it back, never had any problems after that...

Some half-baked improvisations

Fishing line hold down for window glass.

The line goes over the top of the window

The edge of a heavy polythene lay-flat field irrigation hose (already has a crease) fitted into, and supplementing, the front window slider. Seems to work but will probably scratch the glass. I was going to also put one in the back but it seems too tight.

Havm't tried glueing the rear glass mounting yet. Thinking I might try Loctite if I can get it, or a cheaper local superglue if I can't.

I had a look at the other side. Although rusty and stiff, its better aligned, the glass is held in by the clips, not by large blobs of sealant, and you can get a socket on the end of the clip securing bolts.

Although driver and passenger side will be different, I wouldn't expect them to deliberately make the drivers side design significantly worse, so I think its had a poor "professional" installation or repair of a poor after market winder replacement.
