Power window wont roll up - 1995 Saturn Sl

Just one, or all? At any rate, it's probably your switch on the door panel. You need to pull the panel off to get to the switch to find the problem. Also ckeck your window motor for operation. May need to put 12 volts there from a battery to check it. Sometimes a wire breaks from chaffing where the wires enter the door. At the switch, with key on, there is one hot wire going in. Find that one and verify that you have power to the switch. If you do, and the motor is functional, then, likely you need a new switch.
