Buy Chevrolet Silverado 1500 Washer Pumps

The washer pump (also called a windscreen washer motor or spray pump) pressurizes the blue washer fluid and squirts it onto the windshield right when the wipers sweep. This quick rinse knocks away mud, bugs, and salty road film so the blades can clear the glass. It runs only a few seconds at a time, which is why it usually lasts many years Wikipedia overview .

• Pump & reservoir sit inside the left-front fender liner; you can see the white cap marked with a washer symbol from above (Chevrolet owner's manual PDF) .
• Fuse 54 (15 A) in the engine-compartment block protects the circuit .
• The pump plugs into a rubber grommet on the tank and uses a single electrical connector plus one fluid hose.

• Fluid sprays weak or only one nozzle works (Auto Repair Oceanside)
• No spray and no pump sound (motor failed or fuse blown)
• "WASHER FLUID LOW" message pops up on the dash when the tank is empty (Chevrolet)

• Blown fuse-often after running the pump while fluid is frozen; check and replace fuse 54 first (JustAnswer)
• Clogged filter/nozzles-dirt or additive crystals restrict flow
• Dry run-time-letting the tank run empty overheats the tiny motor
• Age & corrosion-seals dry out after about 8-10 years, allowing leaks

1. Listen: Have a helper hit the washer switch; a healthy pump buzzes.
2. Fuse 54: Swap in the spare 15 A fuse from the side panel (Chevrolet).
3. Fluid & lines: Make sure the tank is ¾-full in winter so it can expand when it freezes .
4. Nozzle spray test: Pop a pin in the nozzle eye to clear debris.

A step-by-step walkthrough (removing three fender-liner clips, pulling the old pump straight out, and swapping O-rings) is shown in this helpful video guide YouTube: Fast & Easy Pump Replacement . Even first-time DIYers finished the job in about 30 minutes on 2014-2018 trucks.

• Use quality fluid rated at -20 °F or lower; never mix plain water, which can freeze and crack the pump. The manual warns against water-repellent additives that make blades chatter (Chevrolet).
• Cycle the wipers every oil change and change blades about every six months for clear vision (Car Care Council) .
• Top off washer fluid whenever you fuel up-quick habit, big payoff.

GM recalled several 2007-2008 Silverado models equipped with heated washer modules because an internal short could overheat the circuit and, in rare cases, start a fire. The interim repair was simply to pull the heater fuse until a harness kit became available (NHTSA Recall 08048 PDF) . Your 1500 likely does not have the heater, but always run a VIN check at the NHTSA recall portal.

Washer fluid contains methanol, a volatile organic compound (VOC). States such as Texas limit VOC content in "automotive windshield washer fluid" for air-quality reasons (EPA Texas SIP §115.600) . Always recycle empty jugs and wipe spills-methanol harms pets and groundwater.
