Chrysler Dynasty Windshield Washer Pump Replacement Guide (1988-1993)
Everything you need to know about diagnosing and replacing the windshield washer pump on your 1988-1993 Chrysler Dynasty.
- A failing washer pump will result in no spray or a very weak spray, making it a critical safety replacement.
- For a 1988-1993 Dynasty, a new aftermarket pump from a brand like Trico is the most practical and reliable option.
- Always check the washer fluid level and the system's fuse before assuming the pump has failed.
- Replacement is a DIY-friendly task that typically takes less than an hour and requires basic hand tools.
Is Your Windshield Washer Pump Failing?
When the washer pump on your Chrysler Dynasty begins to fail, the symptoms are usually obvious. Because this is an older vehicle, failure is often due to the age of the electric motor or the plastic housing becoming brittle. Here’s what to look for:
- No Spray at All: This is the most common sign. If you activate the washer switch and hear nothing, the pump's motor is likely dead or not getting power. If you can hear a humming sound but no fluid comes out, the pump's internal parts may have failed, or you could simply be out of fluid.
- Weak or Uneven Spray: If the fluid just dribbles out or doesn't reach the top of the windshield, the pump motor is likely getting weak and can't build enough pressure. Before blaming the pump, check if the nozzles on the hood are clogged with wax or debris. You can often clear them with a small pin.
- Pump Runs, But Nothing Happens: If you hear the pump motor whirring but see no fluid, first check that your reservoir isn't empty. If it's full, the pump itself may have an internal failure, or the pickup filter could be clogged with gelled washer fluid.
Pro Tip: Check the Fuse First
Before you order a new pump, always check the fuse for the washer system. A simple blown fuse can mimic the symptoms of a dead pump and is a much easier fix. Also, in very cold weather, your fluid can freeze in the lines or reservoir, which will also prevent the system from working.
Choosing the Right Aftermarket Pump
For a vehicle like the 1988-1993 Chrysler Dynasty, finding a new original equipment (OEM) part from Mopar is highly unlikely. The most practical and cost-effective solution is a new aftermarket pump.
OEM vs. Aftermarket Quality: For a simple component like a washer pump on an older vehicle, a quality aftermarket part provides the same performance as the original. Brands like Trico specialize in wiper and washer system components and are designed for easy, direct-fit installation without needing any modifications. They are built from durable plastic to ensure a long service life. Given the age of the Dynasty, a reliable aftermarket pump is the standard and recommended repair choice.
Installation Overview
Replacing the washer pump on a Chrysler Dynasty is a straightforward job that most DIY mechanics can handle. The pump is press-fit into a rubber grommet on the washer fluid reservoir. The reservoir is typically located in the engine bay, often behind the front bumper cover on one side.
Accessing it usually requires removing the front wheel and the plastic wheel well liner. Once you can see the reservoir, the process is simple:
- Have a bucket ready to catch the old washer fluid.
- Unplug the electrical connector from the pump.
- Disconnect the rubber hose(s).
- Carefully pull the old pump straight out of the rubber grommet on the reservoir.
- Clean the area, install the new grommet (if included), and press the new pump firmly into place.
- Reconnect the hose and electrical plug, refill the reservoir, and test the system.

Frequently Asked Questions (FAQ)
I replaced the pump and it still doesn't work. What now?
First, double-check that the fuse is good. Next, use a multimeter to confirm that the electrical connector is receiving power when the washer switch is activated. If there is no power, you may have a bad switch or a wiring issue. If there is power, you may have received a defective part, or the lines/nozzles are clogged.
Are there any recalls on the Chrysler Dynasty washer pump?
No. While Chrysler has issued recalls for washer pumps on much newer vehicles like the 2016 Dodge Dart, there are no active or historical safety recalls for the windshield washer pump on the 1988-1993 Chrysler Dynasty.
Can I use just water in my washer reservoir?
It is not recommended. Proper windshield washer fluid contains solvents to clean grime and alcohol to prevent freezing in cold weather. Using only water can lead to freezing and damage to the reservoir, lines, and the pump itself. Mixing different types of washer fluid can sometimes cause a gel to form, which can clog the system.
Is it difficult to replace the washer pump myself?
No, this is generally considered an easy DIY job for beginners. The most challenging part is often just getting access to the pump, which may require jacking up the car and removing a wheel and splash guard. No special tools are typically needed beyond basic hand tools.
