Why won't the back windows of my Vauxhall Astra go up all the way?

The back windows of my Vauxhall Astra Twintop aren't going up, they stop about 3-inches from closing. Any advice?
Might be the motors, might be the wiring harness. But if they are partially going up they might simply be sticking in their channels. Try lubricating the channels with silicone grease or Vaseline. If the channels are damaged, replace them (assuming you can get the parts).
