- This is an easy DIY replacement that most owners can complete in under an hour with basic tools.
Is Your Viper's Windshield Washer Pump Failing?
A clear windshield is critical, especially in a car with the performance capabilities of a Dodge Viper. When your washer pump fails, you lose the ability to quickly clear away dust, insects, or road grime. For Viper owners, this isn't a part that fails often, but when it does, it's an easy fix. The symptoms are usually straightforward and easy to diagnose.
Symptoms of a Bad Washer Pump
- No Sound, No Spray: You pull the stalk to wash your windshield and nothing happens. If you don't hear the familiar whirring or humming sound of the pump motor, the pump itself has likely failed or is not receiving power. Start by checking the fuse first. A forum post about Gen 1 Vipers notes the washer motor and wiper motors share a fuse (fuse 18), so if your wipers move but the pump doesn't make noise, the pump is the likely culprit.
- Pump Hums, But No Fluid Sprays: If you can hear the pump motor running but no fluid comes out, the system could be out of fluid. If the reservoir is full, the pump's internal impeller may be broken, or the lines or nozzles could be clogged.
- Weak or Uneven Spray: A weak spray that barely hits the windshield can be a sign of a dying pump that can no longer generate enough pressure. It can also indicate clogged nozzles, so it's worth trying to clean the nozzle tips with a small pin first.
Known Issues, Recalls, and Bulletins
After a thorough search of National Highway Traffic Safety Administration (NHTSA) records and technical service bulletins (TSBs), no specific recalls or widespread issues have been reported for the windshield washer pump on the 1992-2002 Dodge Viper. This is a simple and generally reliable part on these vehicles.
Choosing a Replacement Pump: OEM vs. Aftermarket
When it's time to replace the pump, you have two main choices: OEM from Mopar or an aftermarket part.
- OEM (Mopar): The original part for the 1992-1996 Viper is Mopar part number 4708071. An original part offers a guaranteed fit, but it can be expensive and potentially difficult to find for a vehicle of this age.
- Aftermarket (Trico): For a simple component like a washer pump, an aftermarket part from a reputable brand is a smart choice. Trico is a well-known brand in windshield clearing systems, and their pumps are designed to be reliable, easy-to-install, OE-style replacements. For the Viper, an aftermarket pump provides the same function as the original at a much lower cost, making it a practical and budget-friendly repair.
Pro Tip: Use the Right Fluid
Using incorrect fluids like glass cleaner or plain water can damage the pump and other system components over time. Always use a quality windshield washer fluid to prevent premature failure and keep the system clean.
Replacement Cost

Frequently Asked Questions
Is replacing the washer pump a difficult job?
No, this is a great DIY task for Viper owners. It typically requires basic hand tools. You will likely need to access the pump by removing the front passenger-side wheel and wheel well liner to get to the washer fluid reservoir. The pump itself usually just pushes into a rubber grommet on the reservoir. The entire job can often be done in under an hour.
Where is the windshield washer pump located on a 1992-2002 Dodge Viper?
The pump is located at the bottom of the windshield washer fluid reservoir. On most vehicles of this era, the reservoir is situated in the front of the car, often behind the front bumper cover or a fender liner, typically on the passenger side.
Do I need to drain the washer fluid to replace the pump?
Yes. The pump sits at the bottom of the reservoir, so the fluid will spill out when you remove the old pump. It's best to either run the pump until the reservoir is empty (if it still works) or have a bucket ready to catch the fluid when you pull the pump out of its grommet.
My pump is working, but the spray is weak. What else could it be?
If you can hear the pump running strong, check for other issues before replacing it. The spray nozzles on the hood can get clogged with wax or debris; try cleaning them with a fine needle or pin. Also, check the rubber hoses for cracks, breaks, or disconnected fittings that could cause a loss of pressure.
