Is Your Windshield Washer Pump Failing?
On a classic car like the 1975-1984 Imperial, the washer system is simple, and troubleshooting is usually easy. The most common point of failure is the electric pump motor wearing out after decades of use. The signs of a bad pump are typically very clear.
Common Symptoms of a Bad Washer Pump:
- No Sound When Activated: When you press the washer button, you should hear a distinct buzzing or whirring sound from the pump. If you hear nothing, and you've already checked the fuse, the pump motor has likely failed.
- No Fluid Spraying: If the pump makes no sound and no fluid comes out, it's a strong sign the pump is dead. Make sure your reservoir is full first.
- Pump Runs, But Spray is Weak or Absent: If you can hear the pump running but the spray is weak, uneven, or non-existent, the pump's internal impeller may be worn out and unable to generate enough pressure.
Pro Tip: Check the Easy Stuff First! Before you replace the pump, check for a blown fuse in your Imperial's fuse panel. Also, use a small pin or needle to clear any debris from the washer nozzles on the hood, as they can get clogged over time. Sometimes a cracked or disconnected rubber hose is the culprit.
Choosing the Right Aftermarket Pump
For a vehicle from this era, finding a "New Old Stock" (NOS) OEM part is very difficult and expensive. The most practical, reliable, and affordable solution is a new aftermarket pump.

Frequently Asked Questions (FAQ)
Is it difficult to replace the washer pump myself?
No, this is a great DIY job for beginners. It typically takes less than 30 minutes and requires basic hand tools. The process involves siphoning the fluid, disconnecting one electrical plug and one hose, and pulling the old pump out of the reservoir before pushing the new one in.
The new pump is installed, but it's still not working. What now?
First, double-check that the electrical connector is plugged in securely. Next, confirm the fuse is good. If those are fine, use a test light or multimeter to see if power is getting to the connector when a friend presses the washer button. If there's no power, the problem might be the switch or the wiring itself.
Is the pump the same for all 1975-1984 Imperials?
Yes, the replacement aftermarket pump is typically a universal or semi-universal style that fits the entire 1975-1984 model year range, as well as many other Chrysler, Dodge, and Plymouth vehicles from that era.
Can I just use water in my washer reservoir?
It is not recommended. Commercial washer fluid contains solvents to clean bugs and grime, as well as antifreeze agents to prevent the lines and pump from freezing and cracking in cold weather. Using only water can lead to pump damage in winter.
Technical Specifications
12-volt electric motor, typically mounts directly to the washer fluid reservoir via a rubber grommet.
