- For this vehicle, a new aftermarket pump from a brand like Trico is the most practical and cost-effective solution.
- Replacement is a simple DIY task that most owners can complete in under 30 minutes.

Signs of a Failing Windshield Washer Pump
A washer pump is a simple part, and its failures are usually straightforward. If you're experiencing issues, it's likely the pump. Here are the common symptoms:
- No Fluid Spraying: You activate the switch, the wipers move, but no fluid comes out. If you can't hear a humming sound from the pump, it's likely dead or not receiving power.
- Weak or Uneven Spray: The fluid barely reaches the windshield or only sprays on one side. This can mean the pump motor is weak and can't generate enough pressure.
- Pump Motor Runs, But No Fluid: You can hear the pump humming, but nothing sprays. This could be an internal failure in the pump, clogged lines, or an empty reservoir.
Check the Basics First
Before ordering a new pump, make sure the washer fluid reservoir is full. Also, check the fuse for the washer system to ensure it hasn't blown. Sometimes, the nozzles or hoses can get clogged with debris; you can try clearing them with a small pin or compressed air.
Choosing the Right Aftermarket Pump
For a vehicle as old as the 1971-1992 Custom Cruiser, finding a new original equipment (OEM) part from GM is nearly impossible. The most practical and common solution is a new aftermarket pump.
OEM vs. Aftermarket:
- New OEM (NOS): New Old Stock parts are original parts that were never installed. They are very rare, expensive, and not practical for a simple part like a washer pump.
- Used OEM: A part from a junkyard is an option, but it's a gamble. You don't know how much life is left in a 30+ year old used pump.
- New Aftermarket: This is the best choice for most owners. Brands like Trico offer direct-fit replacement pumps that are affordable and readily available. Many owners of similar classic GM vehicles have had positive experiences with Trico pumps, noting they are easy to install and work well.
An Easy Upgrade
Many aftermarket pumps for this era of GM vehicle, like the Trico 11-515, are an electric upgrade over the original mechanical-style pumps. Owners report they are a direct replacement, easy to install, and provide a more reliable spray.

Do I need a special pump for the rear window on my wagon?
