- Replacement is a simple DIY job, accessible by removing the passenger-side front wheel and fender liner.
- Quality aftermarket brands like Trico offer a reliable, cost-effective alternative to the OEM part.
Is Your Windshield Washer Pump Failing?
A broken windshield washer pump can be a safety issue, especially in bad weather. Before you buy a new part, it's important to know the signs of failure. Sometimes, the problem isn't the pump itself.
Common Symptoms
- No Sound, No Spray: You push the button and hear nothing. This usually means the pump's electric motor has failed or isn't getting power. First, check the fuse for the washer system. If the fuse is good, the pump is the most likely culprit.
- Sound, But No Spray: You can hear the pump motor whirring, but little or no fluid comes out. This often points to a clog somewhere else in the system. Check the spray nozzles on the hood for debris. You can also check the small rubber filter grommet where the pump enters the reservoir, as it can get clogged with slime from old or mixed washer fluids.
- Weak or Uneven Spray: If the fluid just dribbles out or doesn't reach the whole windshield, the pump motor might be getting weak. It could also be caused by partially clogged nozzles. 🎬 Watch: How to diagnose weak spray and clogged lines. On the ProMaster, the nozzles can be adjusted with a small flathead screwdriver if the spray pattern is just aimed incorrectly.
- Fluid Leaks: Puddles of washer fluid under the front of your van (usually on the passenger side) can mean the pump's plastic housing has cracked or the rubber seal is leaking.
Important Safety Recall Information
Some 2016 model year Ram ProMaster vehicles were part of a safety recall (NHTSA 16V-813 / FCA S83). The original washer pump could create a voltage spike that damages the Body Control Module (BCM), causing the windshield wipers to stop working completely. If you have a 2016 model, it is critical to ensure this recall service was performed. A new pump was the required fix.
Choosing a New Aftermarket Pump
When replacing the washer pump, you have a choice between OEM (Original Equipment Manufacturer) from Mopar and aftermarket parts. For the ProMaster, the price difference is often very small.
- OEM Mopar: This is the exact same part your van was built with. It guarantees a perfect fit and original quality.
- Aftermarket (Trico): Brands like Trico specialize in wiper and washer systems and have been around since 1917. Their pumps are designed to match OEM specifications for fit and function, offering a reliable repair at a competitive price. For a simple part like a washer pump, a quality aftermarket brand is a dependable choice.
Pro Tip: When you replace the pump, it's a good idea to completely drain and clean the washer fluid reservoir. Over time, different brands of washer fluid can mix and form a gel-like substance that clogs the new pump's filter. Flushing the tank with water helps your new pump last longer.

Frequently Asked Questions
Is replacing the washer pump a DIY job?
Yes, this is a very manageable DIY job for most people. Accessing the pump requires removing the front passenger-side wheel and some of the plastic fender liner screws to pull it back. The pump itself just pulls out of a rubber grommet on the reservoir. The entire job can usually be done in under an hour with basic hand tools.
🎬 See this step-by-step walkthrough for replacing the pump.Do I need any special tools?
You will need a lug wrench to remove the wheel, a jack and jack stands for safety, and a screwdriver or trim removal tool for the fender liner clips. No other special tools are typically required.
My pump runs, but nothing sprays. Is it broken?
Not necessarily. If you can hear the motor, the problem is likely a blockage. The most common culprits are clogged nozzles on the hood or a clogged filter screen where the pump enters the reservoir. Try cleaning the nozzles with a small pin and flushing the reservoir before replacing the pump.
🎬 Watch: A quick guide to cleaning and fixing sprayers.Why did my washer pump fail?
Like any small electric motor, washer pumps can simply wear out over time from regular use. Running the pump while the reservoir is empty can also cause it to wear out faster. Clogs in the lines can also strain the motor, leading to premature failure.
