hi all Just wanted to share this info
I have an 07 ex police car, the window would not move, I pulled the switch box out and pulled it apart, very tricky job, springs and clips etc fell out. i found that coffee had been spilt in it and the switch contacts were covered. i cleaned them and put it back together and now it works fine been working good for a year. must warn you that you have to be very careful, I pulled it apart by first placing it in an old babies bath so if a spring or contact fell out it would not be lost, also nearly lost a spring about 2mm in diameter and 5mm long, needed my magnifying glass's to see it. This website (zerone) has a good example of how to get the switch out. (didn't know about it at the time). I went a step further and pulled the switch apart as I thought it was stuffed anyway so no loss if I wreck it. I would rate it about an 8.5 out of 10 for difficulty.
