2018-2020 Tesla Model S Windshield Washer Pump Replacement Guide
Don't let a faulty washer pump compromise your visibility; here's what you need to know.
- A failed washer pump is a common issue, with symptoms ranging from a weak spray to a complete lack of fluid.
- The pump is located behind the front passenger wheel well liner and is a feasible DIY replacement for most owners.
- An aftermarket Trico pump is a cost-effective alternative to the OEM part, offering similar performance.
- Before replacement, always check for simple issues like low fluid, clogged nozzles, or a disconnected hose.
Is Your Washer Pump Failing?
A non-functional windshield washer system can be a safety hazard, especially in poor weather. For the 2018-2020 Model S, the washer pump is a common failure point. If you activate the washers and nothing happens, or the spray is weak, the pump is a likely culprit. Before assuming the pump is bad, always check that your washer fluid reservoir is full and that the nozzles aren't clogged with wax or debris. If you can hear the pump motor whirring but no fluid comes out, the internal impeller may have failed.
Common Failure Symptoms
- No fluid sprays when the washer is activated.
- A weak or inconsistent spray that doesn't effectively clean the windshield.
- The pump motor makes a humming noise, but no fluid is dispensed.
- A puddle of blue or green washer fluid is found under the front passenger side of the car, indicating a leak from the pump or its grommet.
Choosing Your Replacement Part: OEM vs. Aftermarket
When replacing the washer pump, you have two main choices: an original equipment manufacturer (OEM) part from Tesla or an aftermarket part. For the Model S, the pump is a relatively simple component, and aftermarket options can provide the same performance for less money. Brands like Trico design their pumps to meet or exceed original specifications, offering a reliable and cost-effective repair. Since the core function is straightforward, an aftermarket pump is a practical choice for a DIY repair without sacrificing quality.

Pro Tip: Check for Simple Fixes First
Sometimes, a hose can simply pop off the pump, causing fluid to leak out instead of spraying onto the windshield. Before ordering a new part, it's worth inspecting the pump area behind the front passenger wheel liner to see if a hose has become disconnected. Reconnecting it could solve your problem for free.
