Well I have decided to take apart the other door where the window was not working when I bought the car. The lady who sold it to me told me that the car had been broken into and the garage that fixed it stated that the mechanism was too costly to replace etc...apparently she had done this through insurance. I've taken a few photos of the "professional removal" of the insulating material-you can judge for yourself. Anyways the mechanism works as the motor is ok and the tension wire is fine...but the mechanism will not go down far enough for me to unscrew the window...I inspected it as closely as possible and found that there is a wire in the middle of the windowsill from the inside which I am unsure if it should be there...I have taken a photo of it close up and from further away. I was just wondering if it is safe to remove this and then try to fix the window mechanism..I have a feeling that the problem was that they tried to break into the golf and busted the clip just as I did by putting minimal pressure on it..
I don't know why the garage repaired the mechanism as they did...and that the previous owner was happy with the repair..
Please look at the flickr photos and I am hoping I can get some advice on whether I should remove the wire in the windowsill to take a closer look.

It would be nice to have all the windows working for the summer.

..as it looks like it will be a hot one!
