- The windshield washer pump is a simple, low-cost part that is easy to replace for any DIYer.
- Symptoms are straightforward: no spray, a silent motor, or a humming motor with no output.
- Since the B-100 is based on the F-Series chassis, parts like the washer pump are shared with the 1973-1980 F-100/F-150, making them easy to find.
- A new aftermarket pump from a brand like Trico is the most reliable and cost-effective solution.
Is Your Windshield Washer Pump Failing?
A broken washer pump on your Ford B-100 might seem minor, but it can be a safety risk in bad weather. Since the B-100 is based on the F-Series platform, the symptoms of failure are identical to those on the more common F-100 and F-150 trucks of the era. If you hit the washer switch and nothing happens, it's time to diagnose the problem.
Common Symptoms of a Bad Washer Pump:
- No Sound, No Fluid: If you hear nothing when you press the washer button, the pump may have failed electrically, or it might not be receiving power. Check the fuse first before replacing the pump.
- Motor Hums, But No Fluid Sprays: This is a very common symptom. It means the pump's motor is working, but its internal impeller may be broken, or there's a clog. Check the hoses and the nozzles on the hood for blockages before condemning the pump.
- Weak Spray: A dying pump may lose its ability to create enough pressure, resulting in a weak stream that doesn't effectively clean the windshield.
- Leaks: If you notice washer fluid pooling under the front of your truck, the pump's housing or the seal where it enters the reservoir may have cracked from age.
Pro Tip: Check the Basics First
Before spending money on a new part, make sure your washer fluid reservoir isn't empty. Also, use a small pin or needle to clean out the washer nozzles on the hood, as they can easily get clogged with dirt or car wax.
Choosing the Right Aftermarket Pump
Finding a new original equipment (OEM) Ford washer pump for a vehicle this old is nearly impossible. The good news is that the aftermarket provides reliable and affordable solutions. For the 1973-1980 B-100, the system uses a standard 12-volt electric pump that is shared with many other Ford trucks and cars from that period.
Trico is a well-known brand in the wiper and washer industry. They offer universal-style washer pumps that are designed to be a direct replacement for the original. These pumps are engineered to meet or exceed the performance of the factory part and are a dependable choice for this repair. Since this is a simple, low-cost part, a new aftermarket pump from a reputable brand like Trico offers the best value and reliability compared to searching for a used, decades-old original.

Frequently Asked Questions (FAQ)
Where is the washer pump located on my 1973-1980 B-100?
The washer pump is located at the bottom of the plastic washer fluid reservoir. You will find the reservoir in the engine bay, typically mounted to the driver's side inner fender. The pump is press-fit into a rubber grommet on the reservoir.
Is replacing the washer pump a difficult job?
No, this is a very easy job suitable for a beginner. It typically takes less than an hour with basic hand tools. The process involves unplugging the electrical connector, pulling off the fluid hose, and removing one bolt that holds the reservoir in place.
Do I need any special tools?
No special tools are required. You will likely only need a socket or wrench (often 11mm for Fords of this era) to remove the reservoir mounting bolt and possibly a pair of pliers for the hose clamp. A flathead screwdriver can help pry out the old retaining clip if it has one.
Why did my washer pump fail?
Failure is almost always due to age. The electric motor inside the pump simply wears out after decades of use. Running the pump while the reservoir is empty can also cause it to overheat and fail prematurely.
Are there any recalls for the washer pump on my B-100?
No, there are no known recalls or Technical Service Bulletins (TSBs) from the NHTSA related to the windshield washer pump for the 1973-1980 Ford B-100 or related F-Series trucks. Any failure is due to the age and wear of the component.
