Is Your Windshield Washer Pump Failing?
A non-working windshield washer system is more than an inconvenience; it's a safety issue. If your 1997-1998 S90's washers aren't spraying, the pump is a likely culprit. This component can fail from age, wear, or even from running the reservoir dry too often, which can cause the small motor to overheat. Diagnosing the problem is usually straightforward.
Common Failure Symptoms
Before you replace the pump, make sure it's the part that has failed. Check for these common signs:
- No Sound, No Fluid: You press the washer button and hear nothing. This often points to a dead pump motor or an electrical issue, like a blown fuse. First, check the fuse box for the washer system. If the fuse is good, the pump itself has likely failed.
- Pump Hums, But No Fluid Sprays: You can hear the pump motor whirring, but little or no fluid comes out of the nozzles. This could mean the reservoir is empty, the nozzles or lines are clogged, or the pump's internal impeller has failed and can no longer generate pressure.
- Weak or Uneven Spray: The fluid barely reaches the windshield or sprays unevenly. This can be caused by clogged nozzles, but it's also a sign of a weak pump that is beginning to fail.
- Fluid Leaks: If you notice a puddle of blue washer fluid under the front of your car, the pump body or the grommet sealing it to the reservoir may have cracked or perished, causing a leak.
Check for Other Issues First
Sometimes, the pump isn't the problem. In many Volvos, a common failure point is a small plastic T-connector in the washer fluid line under the hood. If this connector breaks, fluid will spill into the engine bay instead of reaching the spray nozzles. Also, ensure your washer nozzles aren't simply clogged with wax or debris before condemning the pump. A simple cleaning with a small pin may restore flow.
Choosing the Right Aftermarket Pump
For the 1997-1998 Volvo S90, you don't need to pay dealership prices for a Genuine Volvo part. Several aftermarket brands offer direct-fit replacements that provide good value. However, quality can vary significantly.
Brand Quality Tiers
- Good - Trico: Trico is a well-known brand in wiper and washer systems. Their pumps are presented as easy-to-install, direct-fit replacements that don't require modification. They are a reliable, budget-friendly choice for a standard repair.
- Acceptable - Vemo: Vemo manufactures a wide range of electronic automotive parts and positions itself as an OE-quality supplier. While reviews are not extensive for this specific Volvo application, they can be a viable mid-range option if available.
- Use with Caution - URO Parts: URO Parts is known for being one of the cheapest options available. However, numerous forum discussions across different car communities, including Volvo, report poor quality, incorrect fitment, and premature failure of their parts. While some have used their non-critical components without issue, it's generally considered a low-tier brand. Given the relatively low cost of better-quality pumps and the labor involved, it may be wise to spend a little more for a more reliable brand.
OEM vs. Aftermarket
The original washer pump for your S90 is part number 9178094. While a Genuine Volvo part offers a guaranteed fit and quality, a reputable aftermarket brand like Trico can provide similar performance and longevity for a fraction of the cost, making it a smart choice for this repair.
Replacement Cost
Replacing the windshield washer pump is a budget-friendly repair, especially if you do it yourself. The main cost is the part itself, with labor being the other variable.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Pump | $20 - $40 |
| Shop Labor | $80 - $150 |
| Total Estimated Cost | $100 - $190 |
Note: Costs are estimates and can vary based on your location and local labor rates. The estimated shop labor cost for a 1998 S90 is between $124 and $183 according to some sources, but can be lower.
Frequently Asked Questions (FAQ)
Where is the washer pump located on a 1997-1998 Volvo S90?
The windshield washer pump is located at the bottom of the washer fluid reservoir. To access it, you will likely need to jack up the front passenger side of the car, remove the wheel, and then remove the plastic inner fender liner to expose the reservoir and pump.
Can I replace the washer pump myself?
Yes, this is a very DIY-friendly job for someone with basic tools. The process involves siphoning the fluid from the reservoir, accessing the pump, disconnecting the electrical connector and hose, and pulling the old pump out of the reservoir grommet. Installation is the reverse of removal. The pump is typically a simple push-fit component.
Do I need any special tools?
No special tools are required. You will need a jack and jack stands, a lug wrench to remove the wheel, and basic hand tools (like a socket set or screwdrivers) to remove the fender liner. A bucket to catch any remaining washer fluid is also recommended.
My car has headlight wipers. Does it use a different pump?
Vehicles with headlight wipers often have a second, separate high-pressure pump for that system. The pump for the windshield is a standard, single-outlet pump. Ensure you are ordering the correct pump for the windshield washer system.
Should I replace the rubber grommet with the pump?
Yes. It is highly recommended to replace the small rubber grommet that seals the pump to the reservoir. New pumps often include a new grommet. The old one can become hard and brittle, and reusing it often leads to leaks.
