Replacing the Windshield Washer Pump on Your 1969-1972 Fargo D110 Pickup
A clear windshield is critical for safety, and a working washer pump is a key part of that system on your classic truck.
- The 1969-1972 Fargo D110 is mechanically identical to the Dodge D100, so parts are interchangeable.
- A new aftermarket pump is the only practical option and offers modern reliability.
- Symptoms are easy to diagnose: no sound means a likely electrical issue or dead pump; sound but no spray means a clog or empty reservoir.
- Replacement is a simple DIY task that can be done in under 30 minutes with basic tools.
Is Your Fargo D110's Windshield Washer Pump Failing?
For a truck of this era, the windshield washer system is straightforward. If it stops working, the pump is a likely culprit. Diagnosing the problem is usually simple.
Common Failure Symptoms
- No sound from the pump: When you activate the washer switch, you should hear a distinct humming sound from the pump. If it's silent, the pump may have failed or is not receiving power.
- Pump hums, but no fluid sprays: If you can hear the pump working but no fluid comes out, the issue could be an empty reservoir, clogged nozzles, or cracked hoses. It's also possible the pump's internal impeller has worn out and can no longer move fluid.
- Weak or uneven spray: A weak spray that doesn't reach the full height of the windshield can point to a dying pump that can't build enough pressure, or clogged nozzles.
Pro Tip: Check the Simple Things First
Before replacing the pump, make sure the washer fluid reservoir is full. Check the hoses for obvious cracks or leaks. Use a safety pin to clear any debris from the spray nozzles on the hood. Also, check the fuse that controls the washer system to ensure it hasn't blown.
Fargo D110 vs. Dodge D100: What's the Difference?
Fargo trucks were a brand of Chrysler, sold primarily in Canada and for export, and were essentially re-badged Dodge trucks. Your 1969-1972 Fargo D110 is mechanically identical to a Dodge D100 from the same period. This is great news for parts availability, as components listed for the more common Dodge D100 will fit your Fargo perfectly.
Choosing a New Aftermarket Washer Pump
Finding a new original equipment (OEM) washer pump for a 50-plus-year-old truck is nearly impossible. Aftermarket parts are the go-to solution, offering modern reliability for your classic vehicle. For the 1969-1972 Fargo D110, new aftermarket pumps are readily available and affordable.
- Trico: Trico is a well-known brand in wiper and washer systems. An aftermarket Trico pump is a reliable, direct-fit replacement that often provides better performance than the original mechanical units. Some owners of similar classic trucks have noted that new electric replacement pumps are more powerful than the originals.
Given the age of the vehicle, a new aftermarket pump from a reputable brand like Trico is a significant upgrade over a worn-out original or a used part of unknown condition.
Known Issues, Recalls, and Service Bulletins
There are no active recalls or Technical Service Bulletins (TSBs) from the National Highway Traffic Safety Administration (NHTSA) specifically for the windshield washer pump on the 1969-1972 Fargo D110 or the equivalent Dodge D100. Any issues with the washer system are typically due to the age and wear of the components rather than a manufacturing defect.
Frequently Asked Questions
Where is the windshield washer pump located on a 1969-1972 Fargo D110?
The washer pump is typically located on or at the bottom of the windshield washer fluid reservoir in the engine bay. On some classic trucks of this era, the pump was integrated with the wiper motor assembly. Check your specific vehicle to confirm its location.
Is it difficult to replace the washer pump myself?
No, this is a very straightforward job for a DIYer. It usually involves unplugging an electrical connector, disconnecting two hoses, and removing a screw or clip holding the pump in place. The entire process can typically be completed in under 30 minutes with basic hand tools.
Why does my new pump run but not spray fluid?
This is often due to an air leak in the suction hose running from the reservoir to the pump, or the pump needing to be primed. Ensure the hose is fully submerged in fluid and has an airtight seal. You can try priming the pump by filling the lines with fluid before connecting them. Also, double-check that the hoses aren't kinked and the nozzles aren't clogged.
Will a new pump fix a weak spray?
In most cases, yes. A new pump will restore the pressure needed for a strong, effective spray. However, if the nozzles are partially clogged with wax or debris, you should clean them with a pin to ensure the new pump can work effectively.
