Is Your Windshield Washer Pump Failing?
When the washer pump on your 1988-1993 Dodge Dynasty starts to fail, the signs are usually clear. Before you decide to replace the pump, make sure to check the simple things first: ensure the washer fluid reservoir is full and check the fuse for the washer system. If those are fine, you likely have a pump-related issue.
Common Failure Symptoms:
- Pump is Silent: You activate the switch and hear nothing. This usually means the pump motor has failed or there's an electrical problem preventing it from getting power.
- Pump Hums, No Fluid Sprays: You can hear the pump motor running, but no fluid comes out. This can happen if the pump's internal parts are broken, the hoses are clogged, or the nozzles are blocked.
- Weak Spray: The fluid barely reaches the windshield or just dribbles out. This is a sign that the pump motor is getting weak and can no longer create enough pressure.
- Fluid Leaks: If you see a puddle of washer fluid under the front of your car, the pump's housing or the rubber grommet sealing it to the reservoir may have cracked or deteriorated.
Pro Tip: Check Hoses and Nozzles First
Before replacing the pump, take a moment to inspect the washer fluid hoses for cracks or disconnection. Also, use a small pin to clear any debris from the metal nozzles on the hood. Sometimes the problem is a simple clog, not a failed pump.
Choosing the Right Aftermarket Pump
For a vehicle like the 1988-1993 Dodge Dynasty, finding a brand-new Original Equipment (OEM) Mopar pump is highly unlikely. The most practical and common solution is a new aftermarket pump. Brands like Trico offer direct-fit replacements that are designed to install easily and function like the original. For a straightforward part like a washer pump, a quality aftermarket unit is a reliable and cost-effective choice that will restore your washer system's function.

Known Issues, Recalls, or TSBs
Extensive searches of the National Highway Traffic Safety Administration (NHTSA) database show several recalls for the Dodge Dynasty, but none are related to the windshield washer pump. Failures of this part are almost always due to normal wear and tear over decades of use. The electric motor simply wears out, or the plastic housing becomes brittle.
Frequently Asked Questions (FAQ)
Where is the washer pump located on my Dodge Dynasty?
The windshield washer pump is located on the washer fluid reservoir. It is a small, cylindrical part that is press-fit into a rubber grommet, usually at the bottom of the reservoir tank. You may need to access it from underneath the car or by moving the reservoir itself.
Can I replace the washer pump myself?
Yes, this is a very beginner-friendly DIY job. The process typically involves siphoning the fluid, disconnecting the electrical plug and hose, pulling the old pump out, and pushing the new one in. It usually requires basic hand tools and can be completed in under an hour.
Does the new pump come with the rubber seal (grommet)?
Most new aftermarket pumps, including Trico, include a new rubber grommet. It is highly recommended to replace the old grommet, as it can become hard and brittle over time and is a common source of leaks.
What if I replace the pump and it still doesn't work?
If a new pump doesn't solve the problem, re-check the fuse for the washer system. You should also use a multimeter to confirm that power is reaching the pump's electrical connector when the switch is activated. If there is no power, the issue may be with the switch, a relay, or the wiring itself.
