Is Your Windshield Washer Pump Failing?
A broken windshield washer pump can be a nuisance and a safety issue. If you're experiencing problems, it's likely the pump has failed. Here are the common symptoms to look for.
Symptoms of a Bad Washer Pump
- No Sound, No Fluid: You push the washer button, and nothing happens. You don't hear the hum of the pump motor, and no fluid sprays out. This usually points to a dead pump or an electrical issue like a blown fuse.
- Pump Makes Noise, But No Fluid Sprays: You can hear the pump motor running, but no fluid comes out of the nozzles. This could mean the reservoir is empty, the lines are clogged, or the pump's internal parts have failed and can no longer push fluid.
- Weak or Uneven Spray: The fluid barely reaches the windshield or only sprays from one nozzle. This can be caused by a dying pump that has lost pressure, or it could be a clog in the lines or nozzles.
Choosing the Right Aftermarket Pump
For a classic vehicle like the 1984-1986 Dodge Conquest (also known as the Mitsubishi Starion), finding a new original equipment (OEM) washer pump from Mopar or Mitsubishi is nearly impossible. Even if you could find one, it would be very expensive. The practical and reliable solution is a new aftermarket pump.
Trico is a well-known brand that produces dependable replacement parts. Their washer pumps are designed to be direct-fit replacements, meaning they install easily without needing modifications. For this application, a Trico pump is a solid, affordable choice that will restore the function of your washer system.

Pro Tip: Check This Before You Buy
Before ordering a new pump, make sure your washer fluid reservoir is full. Also, check the fuse for the washer system to ensure it hasn't blown. Sometimes the nozzles can get clogged with wax or debris; use a small pin to clear them. If these simple checks don't solve the problem, it's time for a new pump.
Installation Guide
Replacing the windshield washer pump on a Dodge Conquest is a straightforward job that most DIY mechanics can handle in under an hour.
- Locate the Reservoir: The washer fluid reservoir is located in the engine bay.
- Gain Access: To get to the pump, you will need to remove the battery and the battery tray.
- Remove the Tank: After the tray is out, remove the washer tank's single mounting bolt and lift the tank out to get easy access to the pump.
- Swap the Pump: Place a bucket underneath to catch any remaining fluid. Disconnect the electrical connector and the fluid hose from the old pump. The pump is press-fit into a rubber grommet at the bottom of the reservoir; simply pull it out.
- Install the New Pump: Press the new pump firmly into the grommet. Reconnect the electrical plug and the hose.
- Reassemble and Test: Place the tank back in position, reinstall the battery tray and battery, and fill the reservoir with new washer fluid. Test the system to ensure it sprays correctly before closing the hood.

Can I replace the washer pump myself?

My new pump runs, but the spray is still weak. What's wrong?
