Is Your Buick Century's Washer Pump Failing?
A failed windshield washer pump is a common issue on the 1994-1999 Buick Century, mostly due to the age of the part. When it fails, you lose the ability to clean your windshield while driving, which can be a safety hazard in bad weather. The most frequent sign of failure is when you activate the washers and the wipers move, but no fluid sprays out. You might also notice that you can't hear the familiar humming sound of the pump motor working.
Common Failure Symptoms
- No Fluid Spray: The most obvious symptom. The wipers move across a dry windshield.
- No Pump Sound: You don't hear the electric hum from the front of the car when you try to use the washers.
- Weak or Inconsistent Spray: The pump motor may be wearing out, resulting in low pressure. This could also be caused by clogged nozzles or lines.
- Leaking Fluid: You might see blue or green washer fluid pooling under the front passenger side of the car. This can indicate a cracked pump housing or a bad seal where it enters the reservoir.
Pro Tip: Before buying a new pump, check two things. First, make sure the washer fluid reservoir is full. Second, check the fuse. On the Century, the wipers and washer pump often share a fuse, so if your wipers work, the fuse is likely good, pointing to a bad pump.
Choosing the Right Aftermarket Pump
For a vehicle like the 1994-1999 Buick Century, you don't need to pay a premium for a dealership part. Aftermarket washer pumps are affordable and reliable. The main difference between brands is often warranty and minor material quality, but all are designed to fit and function like the original.

Frequently Asked Questions
Where is the washer pump located on a 1994-1999 Buick Century?
The windshield washer pump is located on the washer fluid reservoir. You will find the reservoir tucked inside the front passenger-side fender, behind the battery area. It is not visible from the top of the engine bay.
Can I replace the washer pump myself?
Yes, this is a very DIY-friendly job for someone with basic tools. The main steps involve safely jacking up the front passenger side, removing the wheel, and taking out the plastic inner fender liner to get access. The pump itself just pulls out of a rubber grommet on the reservoir. The electrical connector and hose are then swapped to the new pump.
Are there any recalls for this part?
There are no specific recalls for the windshield washer pump on the 1994-1999 Buick Century. There was a recall for the 1997 model year (NHTSA #99V348000) related to the wiper linkage, which could cause the wipers to stop working, but this did not involve the pump itself.
What is the most common mistake when ordering?
The most common mistake is not verifying the electrical connector. While most pumps for this generation of Century are the same, it's always wise to look at the picture of the part and compare it to your original if possible.
