How to fix wiper fluid sprey

"If the windshield wiper fluid of your Chevy Equinox ends up on the rear window instead of the windshield, there could be several possible causes:

Damaged or incorrectly connected windshield wiper fluid tube: The tube that carries the windshield wiper fluid from the reservoir to the base of the front windshield wiper may be damaged or not connected properly, causing the fluid to leak elsewhere.

Clogged windshield wiper fluid outlet: The outlet of the windshield wiper fluid on the base of the front windshield wiper may be clogged with dirt or debris, causing the fluid to flow onto another part of the car, such as the rear window.

Windshield wiper system issues: There may be a problem with the windshield wiper system of your Chevy Equinox that causes the fluid to leak onto other parts of the car instead of the windshield."

try disconnecting the pump for the mist...should be in the wiper fluid reservoir bottle and try again...if the fuse does not blow...the pump could be shorted out

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.

If I remember correctly, your wiper motor is mounted to the firewall, likely on the drivers side. You can locate it easily by turning the key on and turning on the wipers. Just listen to the motor and follow the sound. To see what's going on with the washer portion, you need to carefully remove the plastic cover.
If you have a circuit board inside, be careful not to break it. You need to look at the pump and pump actuator to see what's working or not. (check for voltage and mechanical operation)
To fix it, you can sometimes get a pump rebuild kit but if the electrical part isn't functioning, unless you are trying to keep the car absolutely stock, there are aftermarket external pumps you can add on, using a push button on the dash. It's an easy install and far cheaper than replacing the entire wiper motor assembly. Another option is to go to a scrapyard and find a fluid reservoir from a Chrysler or any other car that uses a pump on the reservoir. Find one that fits reasonably well in your engine compartment and just attach the hoses to your system. Then all you need is a wire from a power source to the push button, then to the pump, and a ground for the pump housing.

Most likely a bad washer fluid pump.

remove the hose from the wiper arm and see if when you push the washer button that the fluid comes out the hose,if it does the sprayer nozzel is plugged if not replace the pupm

check the wiper relay or multi function switch

Here are the following options for activating a rear wiper.

Push button the dash
Pull the wiper lever back (may activate washer fluid on some cars)
Push the wiper lever forward (may activate washer fluid on some cars)
Twist the wiper lever
Push the wiper lever tip if it has a button (may activate washer fluid on some cars)

You might have a bad wiper motor, you can try checking for voltage at the wiper motor connector, if your getting voltage at the connector replace the wiper motor.

check the outside first pull the fluid line where the fluid should be coming out have someone stand there if it comes out there the nozzle is plugged work a pin or needle inside of it to loosen it up if thats the case
