My son had a similar problem with his T reg Vectra when he first bought it last year. I greased the channels for him using silicon grease (you can buy a small tub at most plumbers merchants), operated the window up and down a few times to work the grease in. Gave it one final greasing just for luck! and it's worked fine ever since. Ron
Thank you I had been having an issue with my drivers window. After reading this I used WD40 Specialist silicone lubricant and sprayed from the open window down the sides and after working the grease into the runners it is now fixed.
My window always went down fine but when coming up it would get half way and then open again. I originally thought it was an electrical problem! The only way I could get it to go up was keep tapping the switch until it reached the top.
