If your GMC Acadia's washers have stopped spraying, the fix might be easier and cheaper than you think.

- The pump is located in the front passenger wheel well, requiring removal of the fender liner for access.
- First-generation (2007-2016) models use two separate pumps for the front and rear washers.
- This is a highly recommended DIY repair that can save you significant money on labor costs.
Is Your Acadia's Washer Pump Failing?
When your windshield washers stop working, it's a safety issue. Before you assume the pump is dead, it's important to check a few things. Many owners replace the pump only to find out the problem was something simpler.
Symptoms of a Bad Windshield Washer Pump
- No Sound, No Spray: You press the button, the wipers move, but you hear no humming sound from the pump and no fluid sprays out. This often points to an electrical issue.
- Pump Hums, No Spray: You can hear the pump motor running, but little or no fluid comes out. This could mean the reservoir is empty, the nozzles are clogged, or the lines are blocked or leaking.
- Leaking Fluid: You notice a puddle of blue, green, or orange fluid under the front passenger side of your Acadia. The pump housing can crack over time, or the grommet sealing it to the tank can fail, causing leaks.
Pro Tip: Check the Fuse First!
For the 2007-2016 Acadia, the most common cause of a non-working washer pump is a blown 10-amp fuse. This fuse is located in a hard-to-reach panel under the passenger side glove box. The pump can freeze in cold weather, and trying to use it will draw too much power and blow the fuse. Always check this fuse before buying a new pump.

For a part like a washer pump, you don't always need to pay dealership prices for the OEM part. Quality aftermarket parts can offer the same performance for less money. Your main choices will be between an OEM-spec brand and other aftermarket options.
- ACDelco: This is General Motors' own parts brand. Choosing an ACDelco pump is the closest you can get to buying the original part that came with your Acadia from the factory. It's a safe bet for fit and performance, though it may cost slightly more than other aftermarket brands.
- Trico: Trico is a well-known aftermarket company that specializes in wiper and washer systems. Their pumps are designed to meet or exceed original specifications and are a reliable, cost-effective alternative to the OEM part.
For a straightforward component like this, both ACDelco and Trico are solid choices. The decision often comes down to price and availability.
Cost of Replacing a GMC Acadia Washer Pump
The cost is heavily influenced by whether you do the job yourself or take it to a shop. The part itself is inexpensive, but shop labor can be high due to the time it takes to access the pump.
| Part Type | Part Cost | Labor Cost | Total Estimated Cost |
|---|---|---|---|
| New Aftermarket | $20 - $41 | $200 - $480 | $220 - $521 |
| New OEM | $23 - $64 | $200 - $480 | $223 - $544 |
| DIY Replacement | $20 - $64 | $0 | $20 - $64 |
Installation Notes for DIYers
For first-generation models (2007-2016), the washer fluid reservoir and both pumps are located behind the fender liner in the front passenger-side wheel well. You will need to at least partially remove the liner to get access. While it's not a complex job, it can be awkward.
Prepare for Spills
When you pull the old pump out of the reservoir, all the remaining washer fluid will drain out. Have a bucket ready to catch the fluid before you start.
The pump itself just pushes into a rubber grommet on the tank. The process is to unplug the electrical connector, pull off the fluid hose, and then firmly pull the old pump out. Installation is the reverse of removal.

How do I know if it's the pump or just a fuse?
Listen carefully when you activate the washer. If you hear a faint humming or buzzing sound, the pump is getting power and the fuse is likely good. If you hear nothing but the wipers moving, the fuse is the first thing you should check, especially on 2007-2016 models.
Where is the washer pump on my GMC Acadia?
On 2007-2016 models, the pump (or pumps, for front and rear) is located on the washer fluid reservoir, which is tucked inside the front passenger wheel well. On second-generation models (2017-2021), the reservoir is also in the front of the vehicle, with the pumps attached to it. Access typically requires removing the inner fender liner.
🎬 Watch how to access the reservoir on 2017-2024 models.Can I replace the washer pump myself?
Yes, this is a very feasible DIY job for someone with basic tools. The most difficult part is removing the wheel and fender liner screws to get access. The pump itself is easy to swap. Doing it yourself can save you hundreds of dollars in labor costs.
Do I need a separate pump for the rear washer?
On the first-generation Acadia (2007-2016), yes. There are two separate pumps mounted on the reservoir—one for the front and one for the rear. They look similar but may have different colored electrical connectors. When ordering, make sure you are buying the correct pump (front or rear) for your needs.
