Jeep Grand Cherokee 1993-2007 Windshield Washer Pump Replacement Guide
Don't let a broken washer pump compromise your visibility—here's how to choose the right replacement for your Grand Cherokee.
- Verify your Grand Cherokee's generation (ZJ, WJ, or WK) to buy the correct pump—setups are different.
- This is a very easy and quick DIY repair that requires only basic tools and saves significant money over shop labor.
- Before replacing the pump, always check the washer fluid level and the corresponding fuse first.
- If you hear the pump motor running but get no fluid, check for clogged nozzles or disconnected hoses before buying a new pump.
Is Your Grand Cherokee's Washer Pump Failing?
A dead washer pump is more than an annoyance; it's a safety hazard. If you activate the washer and nothing happens, the pump is the most likely culprit, especially after checking the fluid level and the fuse. The most common sign of failure is hearing silence when you try to use the washers. If you hear the pump motor whirring but no fluid comes out, you could have clogged lines or nozzles, but the pump itself might also be weak or have a broken internal part.
Symptoms of a Bad Windshield Washer Pump
- No Spray: You pull the lever, and no fluid sprays on the front or rear windshield.
- No Sound: You don't hear the familiar humming sound of the pump motor when you try to use it.
- Weak Spray: The fluid barely reaches the windshield, indicating a weak or dying pump motor.
- Leaks: You notice a puddle of washer fluid under the front driver's side of your Jeep. This can be from the grommet where the pump enters the reservoir.
Choosing the Right Aftermarket Pump for Your Grand Cherokee
For a part like the washer pump, aftermarket options offer excellent value. The original Mopar pumps have lasted a long time, but a new aftermarket part is often a more practical choice than a used OEM part of the same age. The key is buying the correct pump for your specific model year.
Critical Ordering Information: Know Your Generation!
The 1993-2007 Grand Cherokee spans three generations, and the washer pump setup is different for each. Ordering the wrong one is the most common mistake.
- ZJ (1993-1998): Your Grand Cherokee uses two separate pumps located on the washer reservoir, which is found under the hood. One pump is for the front windshield, and the other is for the rear liftgate glass.
- WJ (1999-2004): This generation also uses two separate pumps. They are located on the washer reservoir, which is hidden inside the driver's side front fender. The rear pump is mounted higher on the tank than the front pump.
- WK (2005-2007): The early WK uses a single, dual-outlet pump that serves both the front and rear windshields. It is located at the bottom of the reservoir inside the driver's side front fender/bumper area.
Aftermarket Brand Tiers
For this part, brand choice is less critical than for major engine components, but here's a general breakdown:
- Good - Standard Replacement (Omix-Ada, Trico): Omix-Ada is a well-known name in the Jeep aftermarket world, offering parts that meet basic requirements. Trico is a leader in wiper systems and their pumps are reliable, direct-fit replacements. These brands are budget-friendly and perfectly adequate for this job.
- Better - Reputable Aftermarket (ACDelco, Crown Automotive): ACDelco, while a GM company, produces high-quality aftermarket parts for many vehicles, and their components are widely trusted. Crown Automotive is another Jeep-focused brand, often considered a slight step up in fit and finish from entry-level brands by some Jeep owners.
How Much Does a Replacement Cost?
Replacing the washer pump is an inexpensive repair, especially if you do it yourself. The part itself is affordable, and labor at a shop should be minimal.

| New OEM (Mopar) Pump | $50 - $90 |

Pro Tip: An Easy DIY Job
This is one of the easiest repairs you can do on your Grand Cherokee. The pump is held in place by a simple rubber grommet. Access usually involves removing a few plastic clips or screws in the driver's side wheel well to peel back the liner. No special tools are needed, and the entire job can be done in under 30 minutes. Have a bucket ready to catch the old washer fluid when you pull the old pump out.
Frequently Asked Questions
My front washer works but the rear doesn't. Do I need a new pump?
If you have a ZJ (93-98) or WJ (99-04), yes. You have two separate pumps, so one can fail while the other still works. If you have a WK (05-07), you have one pump, so the issue is more likely a clog in the rear line or a problem with the switch/wiring.
Is there a recall on the washer pump for my Grand Cherokee?
No, there are no active recalls or widespread technical service bulletins (TSBs) for washer pump failure on the 1993-2007 Jeep Grand Cherokee. Failure is typically due to normal age and wear.
Can I replace the washer pump myself?
Yes, this is a great beginner DIY project. The pump is easily accessible on all three generations (ZJ, WJ, WK) by accessing the reservoir. For ZJ models, it's under the hood. For WJ and WK models, you'll need to pull back the driver's side front wheel well liner. The pump pulls straight out. The whole job typically takes less than half an hour.
What tools do I need for the replacement?
You will likely only need basic hand tools. A flathead screwdriver or trim removal tool for plastic clips, and possibly a 10mm socket for a few bolts holding the wheel liner. You won't need any tools to remove the pump itself, as it just presses into the reservoir.
Technical Specifications
Varies by generation. ZJ/WJ models use two separate single-outlet pumps. WK models use one dual-outlet pump. All are 12V electric pumps that press-fit into the washer fluid reservoir.
