Is Your Impreza's Wiper Motor Failing?
For a 1999-2003 Subaru Impreza, the wiper motor is generally a reliable part, but its age can lead to wear and tear. Failure often isn't sudden. You'll likely notice symptoms that get worse over time, giving you a warning before they fail completely.
Diagnosing the Problem: Motor vs. Linkage
Before you replace the motor, it's important to check the wiper linkage. The plastic bushings in the linkage can wear out or break, causing the wipers to have excessive play, move erratically, or not move at all. This can mimic the symptoms of a bad motor. With the wipers off, try to wiggle the wiper arms. If there's a lot of slop, the linkage is likely the problem, not the motor.
Choosing a New Aftermarket Wiper Motor
When replacing the wiper motor on your Impreza, you have a few options. While a new OEM (Original Equipment Manufacturer) part from Subaru is an option, a quality aftermarket part can provide similar performance for less money.
Cardone: Cardone is a well-known brand in the aftermarket, offering both new and remanufactured parts. For the 1999-2003 Impreza, new Cardone wiper motors are available. These parts are designed to meet or exceed original specifications. While some online discussions show mixed reviews for the brand across different parts, their wiper motors are one of their legacy products and are generally considered a reliable, cost-effective solution. They are often built to correct original design weaknesses and are tested to ensure quiet operation and a long life.

Known Issues, Recalls, and Service Bulletins
Searches for the 1999-2003 Subaru Impreza did not reveal any specific recalls or Technical Service Bulletins (TSBs) for the front wiper motor. While Subaru did issue recalls for wiper motors on later model years (2010-2014 Legacy and Outback) due to a risk of overheating and fire, these issues do not apply to the first-generation Impreza. Some owners have reported issues with the wiper switch causing intermittent operation, but this is a separate component from the motor itself.
Frequently Asked Questions
Why are my wipers moving so slowly?
Slow wiper operation is a classic sign of a failing wiper motor. The internal components wear out over time, reducing the motor's power. It can also be caused by grime buildup inside the motor's mechanical parts. Before replacing the motor, ensure the wiper linkage isn't bent or obstructed, as that can also cause slowness.
My wipers stopped in the middle of the windshield. What's wrong?
This is often called a "parking" issue. When you turn the wipers off, a special circuit inside the motor should allow them to return to the bottom of the windshield. If they stop wherever you turn them off, it points to a failure in the motor's internal park switch. This almost always requires replacing the entire motor assembly.
Is it hard to replace the wiper motor on a 1999-2003 Impreza?
For a DIY mechanic with basic tools, this is a manageable job. It typically involves removing the wiper arms, the plastic cowl cover at the base of the windshield, and then unbolting the motor and linkage assembly. The most difficult part can be removing the wiper arms from the splined shafts, as they can corrode and become stuck. A battery terminal puller can be helpful for this step.
Can I just fix my old wiper motor?
While some people have had success opening, cleaning, and regreasing their wiper motor, it is often a temporary fix. Water intrusion is a common cause of failure, leading to internal corrosion and electrical shorts. Given the low cost of a new aftermarket unit and the importance of having reliable wipers, replacement is the recommended and more durable solution.
