How to Replace a Window Motor on a Ford F-150

The Ford F-150 is manufactured with optional electric power windows, which use a motorized window regulator to raise and lower the glass. This motor can wear out and require replacement. The average backyard mechanic can replace a power window motor in a Ford F-150 in about a half-hour.

Things You'll Need

• Socket set
• Screwdrivers

Instructions

1. Disconnect the battery at the positive terminal by turning the bolt in a counterclockwise direction. Stow the terminal away from the battery.

2. Remove the power window switches by prying up one side of the assembly, then pulling them out. The switch assembly has tabs that hold it to the door panel. Disconnect the switch assembly from the wiring harness by pulling the adapter plugs apart, or on some models, by pulling the plug out of the rear of the switch assembly.

3. Remove the inside screws on the interior door handle by turning them counterclockwise with a screwdriver.

4. Remove the armrest bolts by turning them counterclockwise, if applicable.

5. Pull the door panel from the plastic pop rivets that hold it to the metal. Firmly tug on a corner, then work your way around, to disengage the panel from the rivets. Some rivets may become brittle with age and will require replacement.

6. Disconnect the wiring harness from the motor by pulling the adapter plugs apart.

7. Remove the motor by turning the mount bolts counterclockwise, then pulling the motor away from the window regulator gears.

8. Replace the motor by positioning it into the regulator gears, then turning the mount bolts clockwise.

9. Connect the wiring harness to the motor by pushing the adapter plugs together.

10. Replace the door panel by pressing it into the metal, engaging the pop rivets one by one with a firm tap. Replace the armrest bolts and door handle screws by turning them clockwise.

11. Reconnect the switch assembly to the wiring harness by pressing the adapter plugs together. Press the switch assembly into the opening on the door panel until the side tabs engage.

12. Reconnect the battery by turning the positive terminal bolt clockwise.

Tips & Warnings

• Check the window regulator for damage while the door panel is off. Spray the window regulator joints with lithium grease for added protection.
