Everything you need to know about diagnosing and replacing the windshield washer pump on your 2004-2010 Chrysler Pacifica.
- A failed washer pump is a common issue, with symptoms ranging from no sound to a weak spray.
- Before replacing the pump, always check for simpler issues like a blown fuse, empty reservoir, or clogged nozzles.
- Replacement is a simple DIY job that takes less than an hour and requires removing the passenger-side wheel and wheel well liner for access.
- A quality aftermarket brand like Trico offers a reliable, cost-effective alternative to the more expensive OEM part.
Symptoms of a Failing Washer Pump
When your washer pump starts to fail, the signs are usually obvious. Here’s what to look for:
- No Sound, No Spray: The most common sign of a dead pump is when you activate the switch and hear nothing. This means the pump is likely broken or not getting power. Before replacing the pump, it's wise to check the fuse box for a blown fuse related to the washer system.
- Pump Hums, But No Fluid Sprays: If you can hear the pump motor whirring but nothing comes out, the problem might not be the pump itself. This often points to other issues like an empty fluid reservoir, clogged spray nozzles on the hood, or a cracked or disconnected hose somewhere between the pump and the nozzles.
- Weak or Uneven Spray: If the fluid barely reaches the windshield or only sprays on one side, the pump motor could be getting weak and losing its ability to create enough pressure. This can also be a sign of partially clogged nozzles.
Frozen Fluid Warning
In cold climates, washer fluid can freeze in the reservoir, lines, or nozzles, especially if you are using a low-quality fluid or plain water. This will stop the system from working and can make you think the pump has failed. A frozen system can also damage the pump if you run it repeatedly while it's blocked.
Choosing an Aftermarket Pump: Trico
For a straightforward part like a washer pump, an aftermarket replacement is a reliable and cost-effective choice. The original Mopar pump works well, but you are mostly paying for the brand name. Aftermarket brands produce millions of these pumps and offer similar quality for less money.
Trico is a well-established brand in the windshield wiper and washer industry. Their washer pumps are designed to be direct-fit replacements, meaning they install easily without needing any special adjustments or drilling. For a 2004-2010 Pacifica, a quality aftermarket pump from a brand like Trico provides the same function as the original part at a better price point.

DIY Installation Tip
Replacing the washer pump is a great DIY project. The pump is located at the bottom of the washer fluid reservoir. On the Pacifica, you'll need to jack up the front passenger side, remove the wheel, and pull back the plastic wheel well liner to get to it. From there, you just drain the fluid, unplug the electrical connector, pull off the hoses, and pop the old pump out. The new one pushes right in.
Frequently Asked Questions
Why do I hear the pump but nothing sprays out?
This usually means the pump is working, but the fluid isn't reaching the nozzles. Check for an empty reservoir first. If it's full, look for clogged nozzles on the hood (you can clean them with a small pin), or a cracked or disconnected fluid hose under the hood.
Is there a recall on the 2004-2010 Pacifica washer pump?

Can I damage the pump by running it dry?
Yes, running the washer pump for extended periods without fluid can cause it to overheat and burn out. If you suspect the reservoir is empty, refill it before continuing to test the system.
