Tools You'll Likely Need:
* Socket set and ratchets: Various sizes, likely including 8mm, 10mm, possibly others.
* Screwdrivers: Phillips and flathead, various sizes.
* Panel removal tools: To avoid scratching the interior trim. Plastic pry tools are best.
* Torx bits (if applicable): Some Windstars might use Torx screws.
* New passenger-side rear vent window motor: Ensure you get the correct part number for your vehicle.
* Shop rags or paper towels: To keep things clean.
* Possibly a small flashlight or work light: To see into tight spaces.
General Steps (Consult your repair manual for specific details):
1. Interior Panel Removal: You'll need to remove the interior trim panel(s) covering access to the motor. This typically involves removing screws and carefully prying the panels away from the door. Be gentle to avoid breaking clips. The repair manual will guide you on the correct order and technique for removing these panels.
2. Window Regulator Access: Once the panels are removed, you'll gain access to the window regulator mechanism and the vent window motor. The motor is usually attached to the regulator.
3. Disconnect Electrical Connector: Carefully disconnect the electrical connector from the motor. Take note of how it's connected to reassemble it correctly.
4. Remove Motor: This is the tricky part. The method varies slightly depending on the year and specific model. You may need to remove some screws, bolts, or clips holding the motor to the regulator. You may need to manipulate the window regulator slightly to get a good angle to remove the motor. The repair manual is crucial here.
5. Install New Motor: Carefully install the new motor, ensuring it's properly seated and all fasteners are secured.
6. Reconnect Electrical Connector: Carefully reconnect the electrical connector.
7. Reassemble: Reinstall the interior panels, making sure all clips and screws are properly secured.
8. Test Operation: Test the vent window to ensure it's functioning correctly.
Important Considerations:
* Window Regulator: While you're in there, inspect the window regulator for wear and tear. Replacing the regulator is a more involved job, but it's best to address any issues now to avoid future problems.
* Safety: Disconnect the battery's negative terminal before starting work to prevent accidental electrical shocks.
* Repair Manual: I cannot stress enough how important a repair manual specific to your 2003 Ford Windstar is. This guide is a generalized overview and might not cover all the nuances of your specific vehicle. Improper procedures can result in damage to your vehicle or injury to yourself.
If you're not comfortable working on your vehicle, it's best to take it to a qualified mechanic. This is not a beginner-level repair.
