Is Your 1980-1982 Subaru GLF Washer Pump Failing?
When a windshield washer pump fails on a classic car like the GLF, the signs are usually straightforward. After decades of use, the small electric motor inside the pump simply wears out. Before buying a new part, you can quickly confirm the pump is the problem by checking for these common symptoms.
Symptoms of a Bad Washer Pump
| Symptom | What it Means |
|---|---|
| No Sound, No Fluid | You activate the washer switch and hear nothing. If the wipers move but there is no humming sound from the pump, the pump's motor has likely failed or is not getting power. This is the most common sign of a dead pump. |
| Pump Hums, But No Fluid Sprays | You can hear the pump motor running, but no fluid comes out. This could mean the reservoir is empty, the fluid is frozen, or the hoses are clogged or disconnected. If the lines are clear, the pump's internal impeller may have broken. |
| Weak or Uneven Spray | The fluid barely hits the windshield or comes out in a weak dribble. This can happen when a pump motor is getting old and losing pressure. However, you should first check for clogged spray nozzles on the hood, which you can often clear with a small pin. |
Pro Tip: Check the Fuse First
Before you replace the pump, always check the fuse box. A blown fuse is easy to replace and could be the source of the problem. If the new fuse blows immediately, it likely indicates an electrical short inside the old pump, confirming the pump needs to be replaced.
Choosing the Right Aftermarket Pump
For a vehicle like the 1980-1982 Subaru GLF, finding a new original equipment (OEM) washer pump from a Subaru dealer is not a realistic option, as they have been out of production for many years. The best and most practical solution is a new aftermarket part.
Trico is a widely available brand that produces direct-fit replacement washer pumps. These parts are designed to match the original's specifications, meaning they install without needing any modifications. For a simple component like a washer pump, a quality aftermarket part from a known brand will provide reliable performance.
OEM vs. Aftermarket Quality
On a vintage vehicle, new aftermarket parts are often the only choice. A used OEM pump from a salvage yard is a possibility, but its age and condition are unknown. A new aftermarket pump from a reputable brand like Trico offers the best combination of reliability, availability, and value.

Frequently Asked Questions (FAQ)
Can I replace the GLF's washer pump myself?
Yes, this is a great job for a beginner. The pump is located on the washer fluid reservoir in the engine bay. You will need to disconnect the electrical plug and hose, then gently pry the old pump out of its rubber grommet. The new one presses right in. The entire job usually takes less than 30 minutes.
How do I know it's the pump and not just a clog?
Listen for the pump's motor. If you hear it humming when you activate the switch, the pump has power. To confirm, you can disconnect the outlet hose from the pump itself. If fluid squirts out when you hit the switch, the pump is working and the clog is in the hose or at the nozzles on the hood.
Where is the washer pump located on a 1980-1982 Subaru GLF?
The front windshield washer pump is located at the bottom of the washer fluid reservoir. This plastic tank is typically found in the engine bay, near one of the fenders. The pump is a small, cylindrical part pushed into a rubber seal on the tank.
Do I need any special tools to replace the washer pump?
No special tools are required. You may not need any tools at all, though a pair of pliers to help with hose clamps and a flathead screwdriver to gently pry the old pump out can be helpful. You should also have a bucket ready to catch any fluid left in the reservoir when you remove the old pump.
