Re: Rear electric windows
The door has a central runner going vertical in the centre. It connects into a hole in the bottom centre of the rear glass. From the motor there is two cables. One loops round the top of the runner and pulls the window up and the other loops round the bottom of the runner and pulls the window down. The bit thats broken is where it all comes together. Its about 2" square and connects to the glass and cables and slides up and down the metal runner.
I thought of glueing it again and using cable ties as you have suggested...I will let you know how I get on.
