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.

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.
