Is your Impreza's wiper motor acting up? Here is what you need to know before you buy a replacement.
- Failure to 'park' is the most common symptom of a bad wiper motor on this Impreza, caused by an internal switch.
- Before replacing the motor, always check the wiper fuse and ensure the wiper linkage isn't seized.
- Aftermarket brands like Cardone and Replacement offer a cost-effective solution, but be aware of mixed reviews on budget parts and prioritize a good warranty.
- The replacement is DIY-friendly and can be completed in under two hours with basic tools.
Is Your Impreza's Wiper Motor Failing?
A failing wiper motor on a 2004-2009 Subaru Impreza is a common issue as these cars age. The symptoms can range from a minor annoyance to a serious safety hazard. If your wipers stop working during a downpour, your visibility can be reduced to zero in seconds. Understanding the signs of a bad motor helps you diagnose the problem correctly and choose the right replacement part.
Check These Parts First
Before condemning your wiper motor, check the simple things. First, inspect the wiper fuse in the fuse box. A blown fuse will cause the wipers to stop working completely. Second, check that the wiper linkage arms under the cowl panel are not seized or disconnected. A seized linkage can overload and burn out a perfectly good motor.
Common Failure Symptoms
Subaru Impreza owners report several common symptoms when the wiper motor begins to fail:
- Wipers won't park correctly: This is the most frequent complaint. The wipers stop in the middle of the windshield the moment you turn them off instead of returning to the bottom. This is usually caused by a failure of the internal park switch inside the motor assembly.
- Slow or erratic movement: The wipers may move much slower than they should, even on the highest setting. They might also speed up and slow down randomly.
- Only one speed works: Often, the motor will only operate on the high-speed setting when the lower speeds have failed.
- No movement at all: If you hear a humming or buzzing sound from the motor when you activate the switch but there's no movement, the motor has likely failed internally. If you hear nothing, it could be the motor, a blown fuse, or a bad relay.
Choosing the Right Aftermarket Wiper Motor
For a vehicle like the 2004-2009 Impreza, an aftermarket wiper motor offers a great balance of price and performance. While an OEM part from Subaru is an option, it is often significantly more expensive. Aftermarket parts are designed to be direct-fit replacements and can be just as reliable. Here’s a breakdown of the available brands.
Brand Tiers
Standard Aftermarket: Cardone
Cardone is one of the most well-known aftermarket brands, offering both new and remanufactured wiper motors. They are widely available and priced affordably. Cardone states that they re-engineer their parts to fix original design flaws and test them to meet OEM performance. However, owner reviews are mixed; some users report success, while others have experienced premature failures or defects out of the box. If choosing Cardone, ensure it comes with a solid warranty.
Economy Aftermarket: Replacement
The 'Replacement' brand offers a no-frills, budget-friendly option. These parts are designed to match the original's fit and function, providing a straightforward solution for drivers who need a functional repair at the lowest cost. While they may not have the same long-term durability reputation as more expensive brands, they serve as a practical choice to get your wipers working again.
Pro Tip: Test Before You Install
Before you bolt the wiper linkage to your new motor, plug in the motor's electrical connector. Turn the key on, run the wipers for one cycle with the switch on the steering column, and then turn them off. The motor will now be in its correct 'park' position. Now you can attach the linkage, ensuring the wipers will park correctly once everything is reassembled.

Frequently Asked Questions (FAQ)
Is there a recall on the 2004-2009 Impreza wiper motor?
No. While Subaru has issued recalls for wiper motor issues on other models like the 2010-2014 Outback and Legacy, there are no active recalls for the wiper motor on the 2004-2009 Impreza.
Can I just fix my old wiper motor?
Sometimes. If the failure is due to corrosion on the internal park switch contacts, it is sometimes possible to disassemble the motor's gearbox, clean the contacts, and re-grease them. However, this is a delicate repair that may not last. Given the low cost of a new aftermarket motor, replacement is usually the more reliable and time-effective solution.
Why do my wipers only work on the high-speed setting?
This is a common symptom of a failing wiper motor. The different speeds are controlled by separate electrical windings or a resistor block within the motor assembly. When the low-speed components fail, only the high-speed circuit remains functional. The only fix is to replace the entire motor assembly.
Is the wiper motor hard to replace myself?
For a DIYer with basic hand tools, this is a manageable job. The process involves removing the wiper arms, the plastic cowl panel at the base of the windshield, and then unbolting the motor and linkage assembly. The total time is typically 1-2 hours.
