Dodge Dart Windshield Washer Pump Replacement Guide (1979-1990)
A complete guide to diagnosing and replacing the windshield washer pump on your 1979-1990 Dodge Dart.
- The 1979-1990 Dodge Dart is mechanically similar to the US-market Dodge Diplomat (M-body platform).
- Before replacing the pump, always check the fluid level, the fuse, and for disconnected hoses.
- A humming sound with no spray usually points to a clog, not a dead pump.
- For this vehicle, a new aftermarket pump from a brand like Trico is the standard and reliable repair choice.
About the 1979-1990 Dodge Dart
If you own a Dodge Dart from 1979-1990 in North America, you might have a unique piece of automotive history. While the Dart was officially discontinued in the United States in 1976, the name continued in other markets, like Mexico. For this period, the "Dart" name was often used on the same vehicle platform sold as the Dodge Diplomat, Plymouth Gran Fury, or Chrysler Fifth Avenue in the U.S. These cars are known as Chrysler M-bodies. This guide uses information for the M-body platform, which shares the same windshield washer pump.
Symptoms of a Failing Windshield Washer Pump
When a washer pump fails, the signs are usually straightforward. Before assuming the pump is bad, always check two simple things first: make sure the washer fluid reservoir is full and check the fuse for the washer system. If those are okay, here are the common symptoms:
- No Sound, No Fluid: You press the washer button and nothing happens. You don't hear the familiar humming sound of the pump motor. This usually points to an electrical problem, such as a bad pump motor, a failed switch, or a wiring issue.
- Pump Hums, But No Fluid Sprays: You can hear the pump motor running, but no fluid comes out of the nozzles. This often means there is a blockage somewhere in the system. The small filter screen on the pump itself can get clogged with gelled fluid or debris. It could also be caused by a cracked or disconnected hose between the pump and the nozzles.
- Weak or Uneven Spray: The fluid sprays out, but it's weak and doesn't reach the whole windshield. This can be caused by a dying pump that can no longer create enough pressure, a partially clogged line, or blocked washer nozzles.
Pro Tip: Check the Hoses
Before buying a new pump, quickly inspect the washer fluid hoses under the hood. Over time, the plastic and rubber can become brittle. Look for cracks, breaks, or disconnections, especially at any plastic 'Y' fittings that split the fluid flow to the two nozzles. Sometimes a simple disconnected hose is the only problem.
Choosing the Right Aftermarket Part
For a vehicle from this era, finding a new original equipment (OEM) Mopar washer pump is highly unlikely. Even if you found a new old stock (NOS) part, it would be expensive. The standard, reliable repair is to use a new aftermarket pump.
Trico is a well-established brand that produces quality replacement parts, including washer pumps. Their pumps are designed to match the original's fit and function, making for a straightforward installation without needing to modify anything. For this repair, a Trico aftermarket pump is a cost-effective and dependable choice that will restore your washer system's performance.

Frequently Asked Questions (FAQ)
Is replacing the washer pump a DIY job?
Yes, this is a great job for a beginner. It typically requires basic hand tools and less than an hour of your time. The pump is located at the bottom of the washer fluid reservoir. Access may require removing a headlight or part of the plastic wheel well liner, but the process involves simply unplugging the old pump and hoses and connecting the new one.
My pump runs, but the spray is weak or non-existent. What else could it be?
If the pump is running, the issue is likely a blockage. Start by using a small pin or needle to clean out the washer nozzles on the hood. If that doesn't work, disconnect the hose from the nozzles and see if fluid sprays out. If it does, the nozzles are clogged. If not, the clog is likely in the hose or at the pump's filter screen.
Are there any recalls for the windshield washer pump on this vehicle?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database for the Dodge Diplomat and related M-body vehicles from 1979-1990 did not show any recalls specifically for the windshield washer pump.
What kind of washer fluid should I use?
Use a quality, commercial windshield washer fluid. Do not use water, as it can freeze and damage the pump and lines in cold weather. Also, avoid mixing different types or brands of washer fluid, as this can sometimes cause the fluid to gel and clog the system.
