Is Your Windshield Washer Pump Failing?
When a washer pump fails, the symptoms are usually straightforward. The most common sign is that nothing happens when you try to wash your windshield. Before you buy a new part, a quick diagnosis can save you time and money.
- Listen for the Hum: Pull the washer stalk and listen carefully. You should hear a distinct humming or buzzing sound from the pump motor. If you hear nothing, the problem is likely the pump itself or its electrical circuit (fuse or switch). 🎬 Watch: A quick guide on how to test your pump.
- Check the Fuse: Always check the fuse panel first. A blown fuse is a simple and cheap fix. Your owner's manual will have the correct fuse location.
- Hum, But No Spray?: If you can hear the pump running but no fluid comes out, the problem lies elsewhere. Check for clogged nozzles (a small pin can clear them), 🎬 See how to remove and clean Audi 80 washer nozzles. or disconnected, kinked, or cracked hoses running from the reservoir to the hood.
- Leaks: A puddle of blue, green, or orange washer fluid under the front of the car points to a leak. The pump housing itself can crack with age, or the rubber grommet where it seals against the reservoir may have failed.
Choosing the Right Aftermarket Pump
For a vehicle like the 1988-1992 Audi 80, finding a new original equipment (OEM) pump from a dealer is unlikely and would be very expensive. Aftermarket pumps are the most practical and cost-effective solution. They are designed to meet or exceed the original specifications and are a common repair item.
For this specific part, brand choice is less critical than for major engine or electronic components. Aftermarket brands offer excellent value.
- Value Brands (e.g., Vemo): These pumps are a budget-friendly option that gets the job done. For a simple, non-critical part like a washer pump, they offer a good balance of price and function. Forum users have reported success using these brands as a low-cost alternative to OEM parts.
- Standard Aftermarket (e.g., Trico): Trico is a well-known brand in wiper systems. Their pumps are designed as direct OE replacements and are a reliable choice for owners looking for a quality part with a solid reputation.
