So how does it know when to stop on a one touch?
A minor fault on my GT4 that the drivers side doesn't go all the way up at one click but always stop at a random point then I have to press it again to go all the way up.
At first I thought it was my switch but that's all cleaned out and checked and is ok.
What could the cause be and how do I resolve it?

I pulled mine apart to have a look at it and it is all done with tiny electronics... My only recommendation would be to try with somebody elses switch because I think replacement to be by far the easiest solution.

Thanks. I've tried swapping out the switches several times but no difference.
Hence why I'm thinking it's something in the rails or motor mechanism.

It's most likely the motor dying out. But you can try cleaning the rails or adding lubricant or something to it to make it glide better.

So how does the window know when to stop or know when it's hit to top or bottom?
There must be some kind of sensor or micro switch somewhere?

Perhaps there is a safety sensor in there that stops the window if head / arm stuck in closing window, then extra friction could falsely trigger it?

As far as I am informed it is something like a load resistor, when the window hits the bottom or top position the motor is forced to move it even further thus causing it to use more that it's regular amperage. When that happens the circuit closes and power is cut.
