Drivers window....?

[bridgdav]

Well done Podie on sorting out you problem and for giving the advice...

I also have a window issue..... which means that I will need to remove the window parts as well soon...

I have scratching all down the inside of the D/side window, caused by the Aluminium vertical brace scraping on the window when it goes down....

It looks as if the brace is not located or screwed into the inner door skin properly. Also the window channel at the back end of the door has the screw missing, because previous owner must have been a bit over-zealous with the screw driver and stripped the thread...Heli coil here I come....

Does anybody have a similar problem?
Is thw E/Window mechanism easy to remove and replace?
Is the window easy to replace?
Where can I get a new window?
Any idea of cost?

Cheers

Dave

i can't imagine the window motor and window is too hard to remove, the hardest bit is gettin the door panel off havn't actually removed either but had ao good look when servicing a sticking passenger door lock.

Electric window mechanism should be reasonably easy.. the bible is pretty clear in this respect, so I'd use that for guidance.

I was presented with a rubber sheet behind the door trim.. which did surprise me! Basically it looks like it is there to keep noise down or something, and has a few cuts in it for the speaker and door mechanism pull.

I think your biggest issue will be that some of the bolts holding the window mechanism MAY have rusted... as I had my door trim off I gave everything a bit of treatment.

There is a piece of metal bolted to the bottom of the glass which moves up[ a central runner... providing you remove everything out of the way, you should be able to access everything easily enough.

I think the best course of action is to try a TVR garage for the window as it's probably a bespoke part. In the meantime I'd look to find the source of the sratch and resolve that first, before replacing the glass...

Best of luck chap!

I think I will have to strip the door parts in order to do this.

I would like to have a good nose around at other cars at VW if I can to try and determine why the scratches are there.

Haven't all the windows got the TVR logo on them? If so, that suggests a bespoke part. Just be careful with all those tools when you're doing the window work; you don't want to end up breaking the glass and then having to claim again the glass policy on your insurance with its reasonably priced excess!

Isn't that there for waterproofing to handle rainwater etc. that ends up inside the door from the outside of the glass?

HELP....

Removed all the trim last night to access the window Mechanism....

The window is stuck halfway up. There is 12V power to the motor but no whirring...

By the time I had to stop it was getting pretty dark so I couldn't see a great deal.

Does anybody know how the window mechanism works exactly. What does the motor drive to raise or lower the window, there does not appear to be any detail in the Bible.
I'm just wondering if I need to strip the whole lot out to get to any drive mechanism to see if its seized.

Thanks for any help
Rather frustrated...

Well from what I saw, it looked like there was a metal clamp at the bottom of the glass... which riased and lowered (taking the glass with it) via a central metal channel.

I could also see that....But what drives the window up?Is there a helix or screw thread or something enclosed in the round section?
The round section bar id the only thing which looks as though it connects to the motor....

Hmm.. there's the big bit at the bottom which is the motor..

..then the central shaft ( "shaft" ) that the window runs up...

.. so what's in those metal roundish bits located towards the mirror end of the door?

[bridgdav]

I take it nobody really knows what to do then.....?

I'm off home shortly to try again...
I might just whip it all out....

Shame shpub hasn't responded....

Edited to add....

Then I will try to fix the window

SHPUB has been busy....

Sounds as if the car has the spiral inside a tube mechanism which is similar to that used on a wiper motor. The motor may well be a Bosch unit which is pretty well common and these can die. Mine has just gone in the Griff. They are not available as seperate units. The motor has to be bought with the window mechnaism unless you can find a replacement from a scrappy. The Bosch motor has two bolts holding it in place and can then be unscrewed by turning the motor. THis disengages the spiral thread from the window mechanism gear wheel. Use motor to try and get a matching part or alternatively new mechanism.

[bridgdav]

Right here we go...

I ripped the lot out...

Power is getting to the motor but no movement...
Could be the gearbox or the motor itself...



It is a simple vertical screw/worm drive to a round plastic gear connected to the square drive...

Dismantled the motor from gearbox - 24v thro' it and ran lovely, reassembled to the gearbox still fine, the spindle is runnung smoothly and quiet.

So, it must be the linkage and drive to the lifter mechanism.


The main lifter plate is driven up and down by a helix/spring held in the round channel. This is driven by a gear engaged into the helix troughs...



The gear to drive the helix/screw is held in place by a steel cover, which is a riveted sealed unit.

The location and centrality of this gear seems to be the problem.

I haven't taken the unit apart to inspect the gear but it appears that teeth are either pretty worn or stripped. This causes intermittant or no engagement to the helix/screw drive.



So that is where the problem lies, now what to do...

Does anyone have any idea where to get either the full unit or just the drive and channel mechanisms..?

If I strip the drive apart there may be a possibility I can get another gear made...(costly)

Is this the same sort of drive mechanism used in manual window lifters..?

Any help would be most appreciated....

The mechanism is sold as a complete unit. For the Griff the factory sell it for about £50 which I don't think is too bad. It might be worth talking to TVR to see if they have one and what the price is.

The fact that the motor's OK is a blessing as that is really expensive as it pushes the price upto £150 ish.

These units are quite common so it could be possible to match something in a scrappy and then rebuild but to be honest it could be a lot of effort for not much saving.

Guys, I have developed a similar problem with my passenger window. It will go up, but there's a sort of 'clicking'/jerky motion (have i opened myself up to gags there ?!?!?) as the window goes up.

reckon i need to pull out the whole mechanisim and strip it down (oh no, i've done it again !) [enough gags]

hence did a search on here (fantastic wealth of information by the way) and found this thread.

My question is this - on some of the photo's you can see a red tube at the end of the lifter mechanism. only problem is, the photo's are a bit like my view when i take off the door trim - i can't quite see the end of the tubing !!!! is it connected to anything, any wires hanging out or fixed to something?

if not, then i can just undo the bolts holding the mechanism and window guider in place

[bridgdav]

Hi Dave

Been there done that....

Your problem sounds very similar to mine...

The red tube doesn't go anywhere - It is a cover sleve to protect the spiral lifter from getting covered in crud and clogging the gear mechanism.

The chattering is caused by the engagement of the drive gear to the spiral not being made.

The square drive from the motor, winds the gear, which is engaged with the flexible spiral lifter.

At the top end the spiral is connected to a bracket which bolts onto the glass frame.

It sound like the gear is shagged, no or limited engagement. With the play and backlash in the system the window may stop altogether, sticking either up (mine) or down (even worse)

I would suggest getting a new mechanism. TVR direct can get them, but IIRC were quite expensive as the motor came with the assembly....OUCH..!

The mechanism is the same as a Chimera as my new mech came from a write off...

Happy Hunting
