Is Your Windshield Washer Pump Failing?
On a classic truck like the 1970-1979 Toyota Pickup, parts wear out. The windshield washer pump is no exception. After decades of use, the small electric motor can burn out or the plastic housing can become brittle and crack. Here are the most common signs that your washer pump has failed.
| Symptom | What it Means |
|---|---|
| No sound when you activate the washer switch | If you hear absolutely nothing when you try to use the washers, the pump motor has likely failed or isn't receiving power. First, check the fuse. If the fuse is good, the pump itself is the most likely culprit. |
| You hear the pump, but no fluid sprays out | If you can hear a humming or whirring sound from the pump, but no fluid comes out, the problem could be an empty reservoir, clogged nozzles, or disconnected/cracked hoses. On these older trucks, rubber hoses can easily degrade and crack over time. |
| Fluid sprays unevenly or weakly | This usually points to a clog in the nozzles or lines, or a pump that is starting to fail and can no longer create enough pressure. You can try cleaning the nozzles with a small pin to see if that resolves the issue. |
Choosing the Right Aftermarket Pump
For a vehicle from the 1970s, finding a new original equipment (OEM) washer pump from Toyota is nearly impossible. Fortunately, the aftermarket offers reliable and affordable replacements that get the job done.
The brands available, ACDelco and Trico, are both well-established manufacturers of quality replacement parts.
- ACDelco: While known as a General Motors (GM) parts brand, ACDelco produces a wide range of parts for all makes and models. They are known for meeting original equipment specifications for fit and function.
- Trico: Trico specializes in wiper systems. Their washer pumps are designed for easy installation and are a common, trusted choice for replacing a failed original pump.
Pro Tip: For this specific part on a 1970-1979 Toyota Pickup, there is no significant quality difference between these two brands. Both are considered standard replacement grade. Your choice can confidently be based on price and availability.

Frequently Asked Questions (FAQ)
Is it hard to replace the washer pump on a 70s Toyota Pickup?
No, this is a very easy job suitable for beginners. The pump is typically located at the bottom of the washer fluid reservoir, which is easily accessible in the engine bay. The job involves unplugging the electrical connector, pulling the old pump out of the reservoir's rubber grommet, and pushing the new one in.
Do I need any special tools?
No special tools are required. You may need a pair of pliers to disconnect a hose clamp and possibly a screwdriver or small wrench if you need to move the reservoir for better access, but often no tools are needed at all.
Are there any recalls for the washer pump on my truck?
No, there are no recalls or common Technical Service Bulletins (TSBs) from Toyota or the NHTSA for the windshield washer pump on the 1970-1979 Toyota Pickup.
My new pump came with wires but no plug. What do I do?
Some universal aftermarket pumps require you to cut the original connector off and splice the wires using butt connectors. However, many pumps available for your truck are designed as direct-fit and will plug right into the factory harness. It is best to purchase a direct-fit pump if possible to avoid wiring work.
