1999-2003 Ford Windstar Front Wiper Motor: Fixing Park, Speed, and Intermittent Problems

Symptoms of a Failing 1999-2003 Windstar Wiper Motor

A faulty wiper motor can create dangerous visibility issues. Problems often start intermittently and worsen over time. Here are the most common signs that your Windstar's front wiper motor is failing:

• Wipers Won't Park Correctly: This is the most frequent complaint. When you turn the wipers off, they may stop in the middle of the windshield, in the full upright position, or anywhere other than their proper resting place at the base of the glass. This is almost always caused by a failure of the internal park switch inside the motor assembly.
• Wipers Only Work on One Speed: You might find that only the high-speed setting works, while low speed and intermittent settings do nothing. Conversely, they may be stuck on low speed and won't switch to high.
• Slow or Jerky Wiper Movement: The wipers may move much slower than they used to, even on the highest setting. They might also seem to struggle or move in a jerky, hesitant motion across the glass. This can indicate a worn-out motor or internal gear.
• Intermittent Setting Fails: The intermittent (delay) function may stop working entirely, or the wipers will move a few inches and stop, then move a little more on the next cycle instead of completing a full sweep.
• Complete Failure: The wipers won't move at all when you turn the switch on. You might hear a faint humming or buzzing sound from the motor, indicating it's receiving power but is unable to move.
• Blown Fuses: If the motor is shorting out internally, it may repeatedly blow the fuse for the wiper system.

Buying a Used 1999-2003 Windstar Wiper Motor

A recycled OEM wiper motor can be a reliable and cost-effective alternative to an expensive new part or a lower-quality aftermarket unit. Here’s what to inspect before you buy:

Inspection Checklist:

• Verify the Connector: This is the most important check. Make sure the plug on the used motor is an exact match for your vehicle's wiring harness.
• Check for Corrosion: Inspect the electrical pins in the connector for any green or white corrosion. Corroded pins can cause intermittent power issues. Also, check the motor's metal casing for excessive rust, which could indicate it was exposed to the elements.
• Inspect the Output Shaft: Look at the splined shaft where the wiper linkage attaches. Ensure the splines are clean and not stripped or damaged.
• Ask About the Donor Vehicle: If possible, find out the mileage of the vehicle the motor came from. A motor from a lower-mileage Windstar is always preferable.
• Why Used OEM is a Good Choice: An original Ford/Motorcraft part is designed for a perfect fit. The mounting points, shaft size, and electrical behavior are built to factory specifications, which isn't always true for cheap aftermarket clones. Given that the primary failure is often the internal electronics, a tested, working OEM unit provides known quality and fitment.

Known Issues, Recalls, and TSBs

As of mid-2026, there are no specific recalls or Technical Service Bulletins (TSBs) from Ford or the NHTSA for the front windshield wiper motor on 2002-2003 Ford Windstar models.

While there are major recalls for this generation of Windstar concerning rear axle corrosion (Recall 10S13) and front subframe corrosion (Recall 11S16), none address the wiper system. The common failure of the wiper motor's park function is a well-documented issue in owner forums but was never addressed with a specific recall campaign.

Replacement Overview & Difficulty

Replacing the front wiper motor on a 2002-2003 Windstar is a moderately difficult job that a DIYer with basic tools can accomplish in about 1-2 hours.

• Difficulty: 3/5
• Estimated Time: 1.5 hours
• Tools Needed: Ratchet, sockets (15mm or 5/8" for wiper arms, 10mm/11mm for bolts), flathead screwdriver, trim removal tool, possibly a battery terminal puller or small gear puller.

Basic Steps:

1. Mark and Remove Wiper Arms: Use tape to mark the 'parked' position of the wipers on the windshield. Remove the plastic caps at the base of the wiper arms and undo the nuts (typically 15mm). The arms are on a tapered, splined shaft and can be stuck. Wiggle them firmly or use a small puller to pop them off.
2. Remove the Cowl Panel: Remove the plastic clips and screws holding the upper plastic cowl panel at the base 🎬 Watch: How to remove the cowl and wiper assembly of the windshield and remove it.
3. Remove the Wiper Assembly: You will now see the entire wiper motor and linkage (transmission) assembly bolted to a metal plate. Unplug the electrical connector from the motor. Remove the bolts holding the assembly to the firewall and lift the entire unit out.
4. Swap the Motor: On a workbench, unbolt the old motor from the linkage. Note the orientation of the crank arm on the motor shaft before removing it. You may need to tap the linkage off the motor shaft. Bolt the new motor onto the linkage.
5. Reinstallation: Reinstall the assembly, plug in the new motor, and re-attach the cowl. Before putting the wiper arms back on, turn the ignition on and cycle the wipers once, then turn them off. This allows the new motor to find its 'park' position. Then, align the wiper arms with your tape marks and tighten the nuts.
