There are a multitude of things that could be your problem, loose or broken wire, bad control switch, etc. I had the same problem and found that the drive motor was bad. If that is the case, get ready to spend some money. To check, remove the front glass cover, screws on both sides, then there is a set screw that comes up from the bottom, losen that and slide the entire mechanism out of the housing which will expose the motor and wiring. There are 3 wires coming into the motor, one is the ground, one for up and down movement and the one for left and right movement. Use the dash switch (two person job) to apply power and check each wire at the light. You should have power at two of the three when activating the switch.
