Audi 90 Windshield Washer Pump Replacement Guide (1988-1995)
If your washers are dead, the pump is a likely cause and a simple DIY fix.
- A silent pump is the biggest indicator of failure; check the fuse first, then plan to replace the pump.
- Access is through the driver's side wheel well, requiring removal of the wheel and fender liner.
- Aftermarket pumps from brands like Vemo or Trico are affordable and practical for this repair.
- Always have a catch pan ready, as the entire washer fluid reservoir will drain when you remove the old pump.
Is Your Audi 90 Washer Pump Failing?
A non-working windshield washer system is a common issue on the 1988-1995 Audi 90, often due to a failed washer pump. Diagnosing the problem is straightforward. When you activate the washers, listen for the small electric motor. If you hear the pump whirring but no fluid comes out, you could be out of fluid or have clogged nozzles. If you hear nothing at all, the pump has likely failed, or there's an electrical issue like a blown fuse.
Symptoms of a Bad Windshield Washer Pump
- No Sound, No Fluid: You pull the lever and the wipers move, but you hear no humming sound from the pump and no fluid sprays out. This is the most common sign of a dead pump.
- Pump Hums, But No Fluid: If you can hear the pump motor running but nothing hits your windshield, first check your fluid level. If the tank is full, the pump's internal impeller may have failed, or your lines or nozzles are clogged.
- Weak or Uneven Spray: A pump that is getting weak may not have enough power to spray fluid effectively across the entire windshield.
Check Fuses and Hoses First
Before ordering a new pump, always check the fuse for the washer system. Also, pop the hood and look for any disconnected or kinked washer fluid hoses between the reservoir and the hood nozzles, as this can also stop the flow of fluid.
Choosing an Aftermarket Washer Pump: Trico vs. Vemo
For a vehicle like the 1988-1995 Audi 90, an aftermarket washer pump is a practical and cost-effective choice. The original OEM parts can be expensive or hard to find. Both Trico and Vemo are common aftermarket options.
- Vemo: Vemo is known for producing a wide range of aftermarket parts specifically for European vehicles. While some users report good experiences with Vemo parts as a budget-friendly alternative, others have noted inconsistent quality. For a simple part like a washer pump, it is generally considered a decent option.
- Trico: Trico has a long history, since 1917, primarily in wiper systems. Their pumps are designed to be easy-to-install, OE-style replacements. While specific reviews for the Audi 90 are scarce, the brand has a solid general reputation.
Pro Tip: Given the age of the vehicle and the simple function of the part, either brand is a reasonable choice. The most important factor is ensuring the pump you buy is listed as a direct fit for your Audi 90's year to avoid installation problems.
