Another day another opportunity....

The driver's electric window stopped working the other day (as in going up and down...as a window it's still clear and I can still see through it). Obviously it failed in the 'down' position late in the evening...

The switches and motor are not at fault. I've had the door card off and can hear the motor running, and can see/feel the worm gear running through the regulator, but I've not been able to find out - or work out - how the thing all works.

So...do I need a new regulator? I saw something that suggested that something was welded onto a bracket(?) I've struggled to find anything with the precise issues I'm having...

Also how do I go about removing the cassette? Does the whole thing come out of the top? Do I need to separate the glass from the regulator and bring the regulator through the door aperture?

As ever..thank you for any advice...

You should have something like this inside your door!

That flat plate is driven up or down and the glass, which has a metal bracket attached at the bottom, is bolted to it with two M6 bolts.

With the door card and the panel off and the water deflector plastic thing out the way it shouldn't be too hard to see what's moving and what isn't!

I can't see the image - at work... - but the description sounds right. The flat plate does not go up and down, although I can feel the worm circulating inside the rounded tube part of the regulator.

Sounds like something is buggered!

Here's a nearside one but I have no idea whether the parts you would need from it are interchangeable?

Thanks Phillpot...I guess I'll need to find time to get the cassette out and see if I can work out what's gone wrong. Not what I expected, though - I'd assumed that it would just be a case of the window coming off its runners, but doesn't seem to be the case.

Hi, I strongly suspect you will need to change the sliding seals at the same time as fault finding. They are cheap and easy to do, they wear and cause friction, hence window mechanisms are overloaded. The window glass comes out easily. Unbolt it from the (pictured above) slider, at about half way up tilt the back of the glass up, there is some resistance but not much. Once sideways, removal is easy.

The motor along with worm gear etc is the same as fitted to the TX range of black cab taxis. don't fall for the TVR 'tax.' smile

The following is an example. But they are sided. I've changed 2 on Chimaeras and the passenger side front of a taxi does the driver's side. The Griff should be the same but best to check.

Hi all.
For the avoidance of confusion, the spiral wire in the mechanism is not a "worm".
It is in fact a "Rack", does not rotate and is driven longtitudinally by a large gear wheel in the housing beneath the motor.

HTH.

Cheers

The motor and gear housing can be used but the tubing and window slide are totally different

OK, so some cold, dark, and rainy time has passed since last I looked at this...

I've managed to extract the motor and regulator assembly from the door and looked at what's happening.

The rack is operating as expected - i.e.: running up and down the channel - however it is not connected to the bracket which then bolts on to the window. I have extracted the bracket and looks like this.

It feels like this is a simple fix - if only I knew what I was doing. What is - and where should it go - the sticky-out bit of metal?

If the rack is a rack, and not a worm (i.e.: doesn't revolve) then does this need to literally 'stick' into the rack somewhere? Should it be tack-welded to it? Loop round at the top of the rack?

For anyone who stumbles on this at a later date with the same issue, I ended up buying a replacement window regulator.

Glad it is fixed.
