Tailgate Power Window Motor

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 1991 Ford RV Cutaway, 1991 Ford Pickup, 1991 Ford F-Super Duty, 1991 Ford Econoline, and 1991 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Counterbalance spring is under tension! Before removing the motor to test the no-load currents, use the control switch to move the regulator up, thus reducing spring tension. Then lock/clamp the sector gears securely.

To test the current draw of a power window motor, remove the tailgate trim panel. See DOOR TRIM PANEL (BRONCO & F-SERIES)  under REMOVAL & INSTALLATION.

  1. Disconnect the power window motor lead.
  2. Supply power to motor lead connector with an ammeter. See Figure.
  3. Operate the motor and observe the current draw. The current draw for the no-load test should not exceed four amps and should not fluctuate. Reversal of the motor wire connections will reverse the direction of motor rotation. Replace the motor if the current draw exceeds four amps.
