Drivers Window Problem

[samflint1]

Hi

I own a 1995 Celica GT import and i have a problem with the drivers electric window. when i retract the window it is fine but you can hear the motor struggling. when i put the window up you hear the motor engage then almost immediately cut out (a safety circuit i assume), i have taken the door panel off and the window will go up but only when i engage the motor and push it up. I have used half the north seas oil supply on these cables and the mechenism but it hasnt done anything. what i have noticed is where the glass is fixed to the window mech it really pulls the glass in a way twisting it so the mounting plate sits flush. what the hell is going on????

thanks
