2001 Ford Taurus 6 cyl Front Wheel Drive Automatic 95,000 miles
The motor will down down but not up. It does the same when out of the car. I bought a new one, same thing. I used a meter to test the voltage at the socket that feeds the motor. I get 12volts when I press up, and -12 volts when I press down. It has the auto down feature. I can hear a relay clicking when pressing the button. I hate throwing parts at it, please help.
