Golf Cabriolet front door window regulator/motor problem!

[fazersix]

I have seen may posts on regulator issues but none fi my problem. When the drivers window is down and you push the button to raise it, some time when it gets to half way it stops and goes down again! This might happen once or twice and then it goes up! A while ago it was stuck permanently up, a mechanic said that he wiggled the regular wires a bit and it worked again. He said that the motor has a clutch/load sensor that cuts out. Could this be the regualtor cables binding/getting stuck?
Thanks
