Key Takeaways
  • Verify the correct pump for your year, as Classic (pre-1994) and NG900 (1994-1998) models may differ.
  • An aftermarket Trico pump is a reliable and cost-effective replacement for this vehicle.
  • Symptoms include no spray (with or without pump noise) or a weak spray.
  • Replacement is DIY-friendly, requiring access behind the front driver's side wheel liner.
The windshield washer pump is a small electric motor that pushes washer fluid from the reservoir, through hoses, and out onto your windshield. When you pull the washer stalk on your steering column, it sends a signal to this pump. The pump then pressurizes the fluid, allowing it to spray out of the nozzles. A working pump is essential for clearing dirt, grime, and other debris from your view while driving.

Is Your Saab 900 Washer Pump Failing?

A faulty windshield washer pump can be a nuisance and a safety issue. The most common sign of a problem is when no fluid sprays onto the windshield, but you can still hear the pump motor running. This often points to a leak or a clog in the system. If you don't hear the motor at all, the pump itself has likely failed or has an electrical issue, like a blown fuse. Some Saab owners have noted that the check valves in the washer lines can also fail, preventing fluid from passing through.

Generation-Specific Parts

The 1985-1998 Saab 900 range covers two different models: the 'Classic' 900 (up to 1993/94) and the 'New Generation' or NG900 (1994-1998). 🎬 Watch this video to understand the differences between Saab 900 generations. These cars can use different washer pumps. Always verify the part fits your specific model year before purchasing.

Choosing a New Aftermarket Pump

For a vehicle like the 1985-1998 Saab 900, a new aftermarket washer pump is a practical and affordable choice. The original OEM pumps are often difficult to find or prohibitively expensive. Aftermarket brands like Trico offer reliable, direct-fit replacements that meet or exceed original specifications. 🎬 See how Trico aftermarket pumps are designed for a direct fit. These pumps are designed for easy installation without needing special adjustments or drilling. Given the simplicity of the part, an aftermarket pump provides excellent value without a noticeable difference in performance for daily driving.

Part Type Estimated Cost Notes
New Aftermarket (Trico) $24.64 - $35.96 A cost-effective and reliable option.
New OEM $60 - $85+ Harder to source, may not offer significant benefits for the price.
Shop Labor $75 - $150 Typically involves 0.5 to 1 hour of labor.

Replacing the Washer Pump

Replacing the washer pump on a Saab 900 is a straightforward job for a DIYer. The pump is located on the washer fluid reservoir, which is typically accessed by removing the front left-hand wheel and pulling back the fender liner. The process involves disconnecting the electrical connector and hoses, prying the old pump out of the reservoir's grommet, and seating the new one. 🎬 Follow this step-by-step guide to replacing your windshield washer pump. Have a bucket ready to catch any remaining washer fluid.

Pro Tip: When installing the new pump, it's a good idea to transfer the strainer from the old pump to the new one to prevent debris from entering the system.

Frequently Asked Questions

Why do I hear the pump but no fluid comes out?

This usually means the pump is working, but there's a blockage or a leak. Check for clogged nozzles, disconnected or cracked hoses, or a bad check valve in the line. In winter, the fluid or nozzles could also be frozen.

Are there any recalls for the Saab 900 washer pump?

A search of the National Highway Traffic Safety Administration (NHTSA) database did not reveal any specific recalls for the windshield washer pump on the 1985-1998 Saab 900.

Is it difficult to replace the washer pump myself?

No, it is a relatively easy job. It requires basic tools, jacking up the car safely, and removing the wheel and fender liner to access the pump. The replacement itself is a simple plug-and-play process.

Do I need a special pump for the headlight washers?

Yes, on models equipped with headlight washers, there is often a separate, more powerful pump for that system. This guide focuses on the windshield washer pump.
