- Diagnosing the issue is straightforward: check the fuse and listen for the pump motor before assuming the pump is bad.
- Replacement is a common DIY job, typically accessed through the passenger-side wheel well.
- An aftermarket pump from a brand like Trico is a cost-effective and reliable repair for this vehicle.
- Always check for simple clogs in the lines or nozzles before replacing the pump.
Is Your 2001-2006 Mitsubishi Eclipse Windshield Washer Pump Failing?
A non-working windshield washer system is a common issue on many cars, including the third-generation Mitsubishi Eclipse. Usually, the problem is simple. The pump motor wears out, gets clogged, or the electrical connection fails. Before you can get back to having a clear view of the road, you need to know what to look for.
Symptoms of a Bad Washer Pump
- No Sound, No Spray: If you activate the washer and hear nothing, the pump is likely not getting power or has failed completely. Start by checking the fuse first.
- Pump Hums, But No Fluid Sprays: If you can hear the pump motor running but no fluid comes out, the pump might be weak, or there could be a clog. Blockages can happen in the pump itself, the lines, or at the spray nozzles on the hood.
- Weak or Uneven Spray: Fluid that barely reaches the windshield or sprays unevenly can be a sign of a dying pump struggling to create enough pressure. It can also indicate clogged nozzles, which can often be cleaned with a small pin or needle.
First, Check the Simple Things
Before buying a new pump, make sure your washer fluid reservoir is full. Then, check the fuse for the washer system. Sometimes, the problem can also be the switch in the steering column, though this is less common. A quick check of these simple items can save you time and money.
Choosing a New Aftermarket Pump
For a vehicle like the 2001-2006 Eclipse, the original OEM (Original Equipment Manufacturer) pump has likely been discontinued or is expensive. An aftermarket pump is a very practical and affordable solution. Brands like Trico specialize in wiper and washer systems and offer direct-fit replacement parts. These pumps are designed to be installed easily without needing modifications. For a simple component like a washer pump, a quality aftermarket part provides reliable performance at a good price.

Installation Tip
The washer pump is located on the bottom of the washer fluid reservoir. On the 3G Eclipse, this is typically accessed by removing the front passenger-side wheel and pulling back the plastic fender liner. The pump itself is just pressed into a rubber grommet on the tank. Remember to have a bucket ready to catch any remaining washer fluid when you pull the old pump out.
Known Issues, Recalls, and Service Bulletins
Searches for official recalls or Technical Service Bulletins (TSBs) from Mitsubishi or the National Highway Traffic Safety Administration (NHTSA) did not find any specific issues for the windshield washer pump on the 2001-2006 Mitsubishi Eclipse. Any recalls found for washer or wiper systems were for different vehicles or model years. This suggests that failures are due to normal wear and tear rather than a manufacturing defect.
Frequently Asked Questions (FAQ)
How do I know if it's the pump or just a clog?
A good first step is to disconnect the hose right at the pump. Have a friend activate the washer switch. If fluid squirts out of the pump, the pump is working, and your problem is a clog somewhere in the hoses or at the nozzles. If nothing comes out but you hear the pump motor, the pump itself is likely the issue.
Is this a difficult part to replace myself?
No, this is a great DIY job for beginners. The process involves safely jacking up the car, removing the passenger wheel, and moving the fender liner to get access. Basic hand tools are all that's required. The pump pulls out and the new one pushes in.
Do I need to drain the washer fluid first?
Yes, it's a good idea. When you remove the old pump from the reservoir, all the fluid inside will drain out from the hole. It's best to drain it into a bucket beforehand to avoid a mess.
My Eclipse has a rear wiper. Is it the same pump?
Some vehicles use a single pump that reverses polarity to send fluid to the front or rear. However, many vehicles use two separate, smaller pumps that may look identical. When ordering, ensure you are getting the correct pump (front or rear) if your vehicle has that option. The Trico 11-604 is listed for both front and rear applications on the 2000-2006 Eclipse.
