Wiper fluid reservoir location - 2008 Chevrolet Silverado 1500

Have a qualified repair shop check it out . Electronic module involved , WCM - wiper control module . May have code's stored . You have no clue as to how it works.

The windshield wipers are controlled by the wiper control module and the driver-operated multi-function switch on the steering column, with the ignition switch in RUN or ACC position.
There are four modes of wiper operation: OFF position, the wipers move to and stay in the park position; Interval position, the wiper control module causes the wipers to cycle, separated by pauses, pause time length being determined by switch location; LO position, the wipers will operate at low speed continuously; HI position, the wipers will operate at high speed continuously.
The windshield washers are controlled by pressing inward on the wiper switch end of the multi-function switch. The washers will operate as long as the switch is depressed. If the wipers are in the OFF or Interval operating mode, the wipers will begin in LO speed and the washer pump will pump fluid from the reservoir to the nozzles. When the switch is released, the wipers will complete three cycles and then return to their previous setting. In LO or HI mode, no change in wiper operation will occur during washer operation.
The washer fluid level sensor is in the windshield washer reservoir (17618) and is monitored by the hybrid electronic instrument cluster (HEC) and displays a WASHER message when the fluid level is low. The washer fluid level sensor and windshield washer reservoir are replaced as an assembly.

Sounds like you may need to change the washer fluid pump. They do go bad. It's located inside the washer fluid reservoir, which is in the front of the passenger's side wheel well, behind the front bumper.

I'm pretty sure that they share the same reservoir.

CHECK WIPER FLUID LEVEL FIRST ALL IS GOOD CHECK FOR POWER AT WIPER WASHER PUMP MOTOR.IF NO POWER AT WIPER WASHER MOTOR.CHECK 15 AMP FUSE IN THE ENGINE COMPARTMENT FUSE RELAY BOX.IF YES YOU ARE GETTING POWER AT WIPER WASHER MOTOR.WIPER WASHER MOTOR FAULTY.

One can get a repair kit that includes a new motor pump and wiring clips, or

one can get the original motor that plugs into the windshield wiper fluid reservoir.

1999 blazer i m pretty sure uses the same reservoir, its easy to check, look at bootom of res and there should be to pumps. a good way to test wiring and washer button is to wire the rear to frt and hit rear washer button and it should spray frt window, or just use a test light and check for a good ground and power when button is hit hope this helps.

Open the hood and locate your washer fluid reservoir. This is normally located on the driver's side of the engine bay.Locate the fluid pump. It should be underneath the reservoir.Remove the bolts holding the pump to the vehicle's frame.Remove the electo the pump.Install the new washer pump. Installation is the reverse of removal.vote for me if it helps you and you can write a testimonial also.

the water pump is for the engine/radiator.

but the washer fluid motor is at the bottem of the washer fluid reservoir. it will have to wires conecting it to a power/ground. if you can not locate it and there is a hose leading away from the washer fluid reservoir follow it till you reach a motor. will be black, has 2 wires.
