Is Your Windshield Washer Pump Failing?
For a classic car like the 1973-1983 Honda Civic, parts wear out over time. The windshield washer pump is no exception. After decades of use, the small electric motor inside the pump can fail, leaving you without a way to clean your windshield on the go. If you press the washer button and nothing happens, or only a weak dribble comes out, your pump is likely the culprit.
Common Symptoms of a Bad Washer Pump
- No Sound When Activated: You press the button, the wipers move, but you don't hear the familiar whirring or buzzing sound of the washer pump motor. This usually points to a dead pump or an electrical issue. 🎬 Watch: How to troubleshoot your washer pump electrical issues
- Pump Runs, But No Fluid Sprays: If you can hear the pump motor running but no fluid comes out, the issue might be a clog in the hoses or nozzles, or the pump's internal impeller could be broken.
- Weak or Uneven Spray: A dying pump may lose its ability to create strong pressure, resulting in a weak spray that doesn't effectively clean the windshield.
Pro Tip: Check the Simple Things First
Before you replace the pump, make sure your washer fluid reservoir is full. Also, check the fuse for the washer system. On many older cars, the wipers and washer pump share a fuse, so if your wipers work, the fuse is likely okay. You can also use a safety pin to gently clean any debris from the washer nozzles on the hood.
Choosing an Aftermarket Replacement Pump
Finding a brand new, original Honda (OEM) washer pump for a 1973-1983 Civic is nearly impossible. These parts are considered "New Old Stock" (NOS) and are very rare and expensive, usually saved for museum-quality restorations.

Frequently Asked Questions (FAQ)
Is this a difficult part to replace myself?
No, this is a great job for a beginner. The pump is usually located at the bottom of the washer fluid reservoir in the engine bay and is held in by a rubber grommet. You just need to disconnect the electrical plug and hose, pull the old one out, and push the new one in. It typically requires basic hand tools and less than an hour of your time.
🎬 See this walkthrough on how to replace the pumpWere there any recalls for the washer pump on this Civic?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or technical service bulletins (TSBs) specifically for the windshield washer pump on the 1973-1983 Honda Civic.
What if I replace the pump and it still doesn't work?
If a new pump doesn't solve the problem, you likely have an electrical issue or a blockage. Use a test light to confirm you are getting 12-volt power at the pump's electrical connector when the switch is activated. If you have power, check for clogs by disconnecting the hose from the pump and seeing if fluid comes out. If it does, the clog is further up in the lines or at the nozzles.

Usually, no special tools are needed. A pair of pliers to release the hose clamp and possibly a screwdriver or small socket set for access might be required, but the job is very straightforward. Have a bucket ready to catch the washer fluid when you remove the old pump.
