Hey, I have that piece of toothed plastic and it works great. Every once in a while my windows will stick due to excessive periods of none use (car is stored for 364 days a year). I agree that trying to raise the window completely with the plastic tool would take FOREVER, but I am quit sure it would be successful. BTW, the tool saves your fingertip!


I don't quite understand your question. The teeth on that little white wheel you see through through the trim are there for you to raise & lower the window manually (using a piece of toothed plastic - this is according to the owner's handbook. Ha joke!). Even if they were filed flat it wouldn't make any difference to the window operation. That little white wheel is on the worm which enters the gearbox. The gearbox turns the large sprocket-wheel which has the arm that drives the window up/down. The bump-stops which control the travel of the window are on this sprocket-wheel. If your window is stuck up, against the bump stop, it's probably due to some wear on the centre axle of the sprocket wheel - it may not be aligned well with the teeth coming from the gearbox, thus causing it to jam.
This is all very hard to put on paper, but it's all easy to see when you taken the thing apart!
In the early days of my coupe ownership I had sticking windows a bit - nowadays I ALWAYS drop the windows an inch whenever I start the car. Since it's in a lock-up garage, I open don't close them entirely anyway. They really need to be used to keep from jamming up (just like the rest of the car).

And don't worry about them being slow - if you read the Brooklands/R&T books containing all the road tests of the cars back in the early seventies, every road tester complained about the slow windows! They haven't got lethargic with age - they were always that way.

cheers,
Graeme
