A Guide to the 2009-2016 Lincoln MKS Windshield Washer Pump
If your washer fluid isn't spraying, your MKS likely needs a new, affordable washer pump.
- A failed washer pump is a common issue; symptoms include no spray, weak spray, or no pump sound.
- Before replacing the pump, always check the fuse first and make sure the washer nozzles aren't clogged.
- Replacement is a DIY-friendly job that takes about an hour and requires removing the passenger-side front wheel for access.
- A quality aftermarket pump from a brand like Trico offers the same performance as OEM for a lower price, making it a smart choice.
Is Your Lincoln MKS Windshield Washer Not Working?
A failing windshield washer pump is a common issue on many vehicles, including the Lincoln MKS. The small electric motor inside the pump simply wears out from years of use. When it fails, you lose the ability to clean your windshield on the go, which can be a safety hazard in poor weather. Fortunately, this is a straightforward and inexpensive part to replace.
Symptoms of a Failing Washer Pump
Diagnosing a bad washer pump on your MKS is usually simple. Listen and watch for these signs:
- No Sound and No Fluid: If you hear nothing when you activate the washers, the pump is likely not getting power or has failed completely. Always check the fuse first. If the fuse is good, the pump is the most likely problem.
- Humming Sound, but No Fluid: If you can hear the pump motor running but no fluid sprays out, the motor itself is working. This often means the pump's internal impeller is broken and can no longer move fluid. It could also point to clogged washer nozzles or a leak in the fluid lines.
- Weak or Inconsistent Spray: A pump that is starting to fail may lose its ability to create strong, consistent pressure. This results in a weak spray that doesn't effectively reach or clean the entire windshield.
No Recalls for This Part
There are no recalls or technical service bulletins (TSBs) from Lincoln or the NHTSA for windshield washer pump failure on the 2009-2016 Lincoln MKS. Any failure is typically due to normal wear and tear.
Choosing the Right Aftermarket Pump: OEM vs. Trico
For a part like the washer pump, you don't need to pay high dealer prices for the OEM part. A quality aftermarket pump provides the same performance and reliability for less money.
- OEM (Motorcraft): This is the original part that came with your Lincoln. It guarantees a perfect fit and function but is the most expensive option.
- Aftermarket (Trico): Brands like Trico design their parts to meet or exceed original specifications. They are made for a direct, trouble-free installation with no modifications needed. For a simple component like a washer pump, a reputable aftermarket brand is a smart, cost-effective choice that will restore your washer system's function reliably.

DIY Replacement is Feasible
Replacing the washer pump on an MKS is a job most DIYers can handle in about an hour with basic tools. The pump is located on the washer fluid reservoir, which is accessed by removing the front passenger-side wheel and pulling back the plastic fender liner. The pump pulls straight out of a rubber grommet after you disconnect one electrical plug and one hose.
Frequently Asked Questions
Where is the washer pump located on the Lincoln MKS?
The windshield washer pump is attached to the bottom of the washer fluid reservoir. You can access it from the front passenger-side wheel well.
Do I need to drain the washer fluid to replace the pump?
Yes, you should drain the reservoir before removing the old pump. If you don't, all the fluid will spill out when you pull the pump from its grommet. You can either run the pump until it's empty (if it works at all) or siphon the fluid into a clean container to reuse.
My pump runs but nothing sprays. Is the pump bad?
It could be, but first check for two other possibilities. Use a small pin to clean the washer nozzles on the hood, as they can get clogged with wax or debris. Also, check for any visible leaks in the fluid lines. If the nozzles are clear and there are no leaks, the pump's internal mechanism has likely failed.
Is an aftermarket washer pump reliable?
Yes, for this specific part, a quality aftermarket pump from a known brand like Trico is a very reliable and budget-friendly option. The technology is simple, and aftermarket brands produce them to fit and function just like the original.
