WINDSHIELD WIPER FLUID WILL NOT COME OUT BUT WIPERS DO MOVE

"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."

From the 2013 operators manual;

Push the windshield wiper lever forward to spray washer fluid on the rear window. The lever returns to its starting position when released.

The windshield washer reservoir is used for the windshield and the rear window. Check the fluid level in the reservoir if either washer is not working.

Replacing parts just to replace them wont fix a bad wire or part. Better to use a voltmeter and ohn meter to check if your getting power to the wires. You may have a bad connection or bad switch on the column for the pumps. Without checking the circuits it will behard to tell what it is thats wrong. Find a wiring diagram and trace the wires and components.

Tap on wiper motor while it is turned on and see if it moves . Also check the connection at the motor for loose connection and for corrosion . Unplug it and plug it back until it clicks to lock .

Your owners manual will give you fuse location and identification for the rear wiper. Most likely a wiper motor problem though. Turn on rear wiper and grab rear wiper arm and see if it will move at all. If it does move a bit or starts working....the motor is the problem

The rear wiper has its own pump motor. pull the hose from the wiper and have someone engage to see if there is a clog. do the same at the motor. if bo liquid comes out then its the pump. also check fluid level in reservoir as well as a possible secondary reservoir

replace the COMBINATION SWITCH

i have had this exact problem. It's a switch in the steering column. It'll be about $400 to fix

Rear washer may have it's own reservoir . Can you hear a pump humming when you activate the washer? Look in the under flooor compartment

On my 850 the headlight wipers come on the same time as my windshield wipers when I pull the lever to squirt washer fluid on my windshield.
The back wiper should be on an independent switch.
