Is Your Buick Skyhawk's Windshield Washer Pump Failing?
If you activate your windshield washers and nothing happens, or only a weak dribble comes out, the pump is a likely suspect. For a classic car like the 1975-1983 Buick Skyhawk, the original pump may have failed due to age. The good news is that this is a common part and the replacement is straightforward.
Common Failure Symptoms
Diagnosing a bad washer pump is usually simple. Look for these signs:
- No Sound: You press the washer button but don't hear the familiar humming or whirring sound of the pump motor. This often points to a dead pump or an electrical issue like a blown fuse.
- Pump Hums, No Fluid: You can hear the pump running, but no fluid sprays onto the windshield. This could mean the reservoir is empty, the hoses or nozzles are clogged, or the pump's internal components have failed and can no longer move fluid.
- Weak or Uneven Spray: If the spray is weak, it could be due to a failing pump motor that isn't creating enough pressure, or partially clogged lines.
- Leaks: Puddles of washer fluid under the vehicle can indicate a cracked pump housing or a bad seal where the pump enters the reservoir.
Choosing the Right Aftermarket Pump
For a vehicle from this era, finding a new original equipment (OEM) part from GM is highly unlikely. The market consists almost entirely of new aftermarket replacements. Fortunately, the washer pump used on the Skyhawk was a common part across many GM vehicles, making quality replacements easy to find.
Brand: Trico
Trico is a well-established brand in the automotive industry, known for wiper and washer system components since 1917. Their aftermarket washer pumps are designed as direct-fit replacements for the original, meaning they are easy to install without needing modifications. Reviews for Trico pumps on similar vintage GM cars are positive, often mentioning the easy installation and reliable performance. They are made from resilient plastic to ensure longevity.

Frequently Asked Questions
Is replacing the washer pump on my Skyhawk a DIY job?
Yes, this is a great job for a beginner. The pump is usually easy to access, mounted either on the washer fluid reservoir or the wiper motor itself. The replacement typically requires basic hand tools and can be completed in under an hour. The process involves disconnecting the electrical connector, pulling off the hoses, and removing the old pump to install the new one.
Were there any recalls for the 1975-1983 Buick Skyhawk washer pump?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database did not find any recalls or technical service bulletins (TSBs) related to the windshield washer pump for the 1975-1983 Buick Skyhawk.
What is the difference between an OEM and an aftermarket washer pump for this car?
An OEM (Original Equipment Manufacturer) pump would have been made by or for General Motors. However, due to the vehicle's age, new OEM parts are generally not available. Aftermarket parts, like those from Trico, are designed to be direct replacements that fit and function like the original. For this specific part, a new aftermarket pump is the standard and most reliable repair option.
My new pump is installed, but it's still not working. What now?
If a new pump doesn't solve the problem, the issue is likely elsewhere in the system. First, re-check the fuse. If the fuse is good, check for clogs in the washer fluid hoses and the small nozzles on the hood. You can disconnect a hose and blow compressed air through it to clear debris. Finally, there could be an electrical problem, such as a bad switch or a break in the wiring, which may require a multimeter to diagnose.
