The wiper fluid does not come out of the back window. What causes this?

"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."

Sounds like someone has had your washer fluid reservior out and placed the wrong line on the wrong pump. You should have 2 seperate pumps. Pull the reservior up and swap the lines from one to the other, then you should be good.

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.

faulty switch. I would replace that first thing.

Switch is faulty is the first thing comes to my mind. Your spot on tho in your diagnosis, although you may have two pumps and tanks, one for front, one for rear. I would check all my fuses just to be sure, and I would look at all my waster tubes and make sure they are not clogged, check your nozzles too, as sometimes wax can clog them up.

I have the same problem with my 2000 chevy blazer as skornec had posted. I kinda already figured the hose or spray nozzle was plugged. But the problem with checking those items is that I don't know where the hose is located to the back wiper. And the only thing that could be I see that could be the spray nozzle doesn't even have holes that washer fluid could spray from. So basically I just would LOVE if someone could please inform this lame brain of where to find the spray nozzle on the rear window and where in the interior of my blazer does the washer hose run.

If your rear wiper, fluid wash, and rear defrost stopped working at the same time try this first before taking it to the dealer. Start the 4Runner and lower the rear window glass. Wait a few seconds and raise the rear window. Turn the engine off and wait a few seconds. Restart the engine and see if this helps. I had the same problem after I had my drive belt replaced and the shop disconnected the battery cable. When the battery cable is disconnected it causes the rear wiper, fluid wash and defrost to stop working. Good luck!

Get a fine needle and try unblocking the jets in the outlet nozzle first

what is P13K?

check the fuse first. dealer can hook up NGS Tester and get fault codes to see what is wrong.

Principles of Operation
NOTE: The generic electronic module (GEM) will not activate the rear wiper system if either the liftgate or the liftgate glass is ajar. If either the liftgate or the liftgate glass becomes ajar while the rear wiper is in operation, the GEM will park the rear wiper motor.
There are two distinct modes of wiper operation:

• Off Mode: In this mode, there is no rear wiper activity, and the wiper motor will be in the PARK position.
• Interval Mode: This mode is selected when the rear wiper switch is in either the Interval 1 or 2 position. When this mode is selected, the rear wiper motor is driven up onto the glass by activating the rear wiper UP relay. When the wiper motor HIGH/LOW/PARK position input reaches the high position, the UP relay is deactivated and the DOWN relay is activated to reverse the wiper motor direction. When the wiper motor reaches the LOW position, as determined by the HIGH/LOW/PARK position input, the GEM deactivates the DOWN relay and will begin a new wiper cycle 1 to 10 seconds later, depending on the interval position selected.

To engage the rear window washer, rotate the rear window washer selector downward to the WASH position. The rear window wiper will run as long as the WASH position is selected. When the rear window washer selector returns to the OFF, INT 1 or INT 2 position, the washer will stop immediately, but the rear window wiper will continue for two to three sweeps and then return to its previous mode of operation.
The low washer fluid indicator chime warns that the washer fluid level is low. The low washer fluid indicator chime is a single tone with a duration of one second. The chime will sound when the low washer fluid indicator is initially activated.
The low washer fluid indicator warns that the fluid level in the washer reservoir is low. The low washer fluid indicator will illuminate when the washer fluid level is low and the ignition switch is in the RUN position.
The low washer fluid indicator will deactivate when the washer fluid reservoir is filled and the ignition switch has been cycled from RUN to OFF, then to RUN.
Inspection and Verification

1. The wiper/washer system is a generic electronic module (GEM) controlled system; refer to Section 419-10 .

1. Verify the customer concern by operating the wiper/washer system.
