Is Your Windshield Washer Pump Failing?
On a classic car like the Dodge Monaco, parts fail from age as much as from use. The windshield washer pump is no exception. If you activate the washers and nothing happens, or the spray is weak, the pump is a likely culprit. Before replacing it, always check the simple things first: make sure you have fluid in the reservoir, check the fuse for the washer circuit, and use a small pin to clear any debris from the washer nozzles themselves.
Common Symptoms of a Bad Washer Pump
- No Sound, No Spray: If you don't hear the hum of the pump motor when you activate the switch, the pump has likely failed or isn't receiving power.
- Pump Hum, Weak Spray: If you can hear the pump running but the spray is weak or inconsistent, the pump's internal impeller may be worn out and unable to build enough pressure.
- Leaks: Puddles of washer fluid under the reservoir can indicate a cracked pump housing or a failed seal where the pump enters the reservoir.
Choosing the Right Aftermarket Pump
Finding a new original equipment (OEM) Mopar washer pump for a 1967-1979 Monaco is nearly impossible, as they have not been produced for decades. Your main options are a used original part, a New Old Stock (NOS) part which can be very expensive, or a new aftermarket replacement. For a part like this, a new aftermarket pump is often the most practical and reliable choice.
Trico is a well-known brand that has been specializing in wiper and washer systems for a very long time. Their aftermarket pumps are designed to be direct-fit replacements, meaning they should install without modification. They are built to modern standards and offer a dependable and affordable solution to get your washer system working again.
Pro Tip: When replacing the pump, it's a good idea to also replace the small rubber grommet that seals the pump to the reservoir. Most new pumps, including those from Trico, come with a new grommet. This helps prevent leaks.

Frequently Asked Questions (FAQ)
Is it hard to replace the washer pump on a 1967-1979 Monaco?
No, this is a very easy DIY job for most owners. The pump is typically located on the washer fluid reservoir and is easily accessible. The job usually involves disconnecting a wire, a hose, and pulling the old pump out. No special tools are required.
How do I know if it's the pump or just a clog?
First, listen. If you activate the washers and hear the pump motor humming, but no fluid comes out, the problem could be a clog in the lines or nozzles. Disconnect the hose from the pump and activate it again. If fluid comes out of the pump, the pump is working and the clog is elsewhere. If you hear nothing, the pump itself is the likely issue.
Will an aftermarket Trico pump fit correctly?
Yes, reputable aftermarket brands like Trico design their pumps to match the original equipment specifications for a direct fit. This means the electrical connector and hose port should line up without any need for modification.
Are there any recalls for the Dodge Monaco washer pump?
No, there are no specific recalls for the windshield washer pump on the 1967-1979 Dodge Monaco. Recalls for washer pumps on other, much newer Dodge vehicles exist but are related to modern complex electronics and do not apply to this classic model.
