- Replacement is a simple DIY task, typically taking less than 30 minutes with basic tools.
- ACDelco is a premium choice that matches original factory quality, while Trico offers a reliable, budget-friendly alternative.
- Always replace the rubber grommet with the pump to prevent future leaks.
Is Your Windshield Washer Pump Failing?
A failing washer pump on your 1992-1993 GMC Typhoon can be a safety issue, especially in bad weather. Here are the common signs that your pump is going bad:
- No Fluid Spray: You press the button, but nothing comes out. If the reservoir is full, the pump is the likely culprit.
- Weak or Uneven Spray: The fluid barely reaches the windshield or comes out in a weak dribble. This can indicate a dying pump motor.
- Pump Is Silent: You should hear a distinct humming sound from the pump when you activate it. If it's completely silent, the pump motor has likely failed or is not receiving power.
- Pump Hums, But No Fluid: If you hear the pump running but see no fluid, the pump's internal impeller might be broken, or the lines could be clogged.
- Fluid Leaks: You may find a puddle of washer fluid under the front of your truck. The pump body or the grommet that seals it to the reservoir can crack and leak over time.
Check the Simple Things First
Before buying a new pump, make sure your washer fluid reservoir is full. Also, check the washer nozzles on the hood to ensure they aren't clogged with wax or debris. In freezing weather, the fluid in the lines can freeze, which also prevents spraying.
Choosing Your Aftermarket Replacement Pump
For a specialty vehicle like the Typhoon, finding parts can sometimes be a challenge, but the windshield washer pump is a component shared with many other GM vehicles from that era. This makes finding a reliable aftermarket replacement straightforward. An aftermarket part is a new part made by a company other than your vehicle's original manufacturer.
Brand Tiers: ACDelco vs. Trico
ACDelco: Often considered the top-tier choice for GM vehicles. ACDelco is GM's original parts brand, so their products are manufactured to the original equipment (OE) specifications for fit and function. Choosing an ACDelco pump is the closest you can get to the original part your Typhoon came with from the factory. They are known for reliability and durability.
Trico: A well-respected name in the aftermarket, Trico is primarily known for wiper blades but also produces reliable washer system components. Their pumps are designed for easy installation and are a cost-effective alternative that provides dependable performance. Trico sometimes offers universal-fit pumps, but for the Typhoon, a direct-fit model is available and recommended.
Pro Tip: Many aftermarket pumps, including those for your Typhoon, come with a new rubber grommet. Always replace the old grommet when you install the new pump to ensure a leak-free seal with the reservoir.

Frequently Asked Questions

It requires basic hand tools and can often be completed in under an hour.

No, a search of the National Highway Traffic Safety Administration (NHTSA) database shows no specific recalls or technical service bulletins (TSBs) for the windshield washer pump on the 1992-1993 GMC Typhoon.
Do I need a special pump for the GMC Typhoon?
No, the Typhoon uses a standard GM washer pump that is shared with many other vehicles from the same period, including the GMC Syclone, Chevy S-10, and Astro van. This makes finding a compatible aftermarket part easy.
