Windshield wiper liquid pipe lickage

"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."

There is a electric motor that pumps washer fluid . Located in the bottom of the washer fluid tank .
Wash Operation (Front and Rear Wipers)
The front and rear washer systems use the same windshield washer fluid pump. When either the front or rear wiper is in the washer position voltage will be supplied to one side of the windshield washer fluid pump (depending on whether it is front or rear), while the other side of the pump is grounded.
At this point, the windshield washer fluid pump sprays solvent onto the windshield. When the front or rear washer is activated, the BCM receives an input from the switch that is activated. The BCM will control the wipers while in the WASH mode. The BCM will control either the front wiper relay or the rear wiper relay to turn on the wipers. The windshield wipers operate at low speed for 3 swipes and returns to the park position.

When turning on the washers do you hear the motor run ? Have some one try it while you listen at the washer fluid tank ! These pump motors do go bad .
turn OFF the ignition.
Disconnect the harness electrical connector of the windshield washer fluid pump.
Connect a test lamp from the windshield washer pump control circuit to a good ground .
Turn ON the ignition, with the engine OFF.
Press the front washer switch.
Does the test lamp illuminate?
YES or NO !

pipe from washer bottle could be cracked or perished. try follow pipe from water bottle to sprayers and check condition of pipe. sounds like leak is close to bottle

There's a few things you might want to check. First, check to make sure the washer fluid reservoir is completely (assuming you hadn't already done that). After you are certain the reservoir is full, look for any possible leaks...either the reservoir or the hoses going from the tank to the windshield. If the tank and hoses are intact, turn on your windshield wipers...then try running the pump. If no washer fluid comes out, and for this you might need another person to assist you, try running the pump again...listening to make sure the pump is in fact running. If the pump does run but still no fluid comes out, inspect all of the hoses as well as all of the outlets where the fluid sprays the windshield...it is possible that the outlets may be plugged. Some common reasons for the outlets to be plugged...debris, dirt/mud, and/or wax (has anyone recently waxed your Freightliner?). Just to be sure, using a small needle or even a wire, ensure each outlet is cleared and not obstructed with anything. After that, try running the pump again. If no luck, try removing the hoses going from the tank to the windshield. Once removed, using something like a wire coat hanger, clear each hose for any possible obstruction. Reattach hoses and try running pump again. If still no luck, I would guess the problem might be located with the washer pump itself. Before opting to replace the pump, if you believe that is the problem and the pump just doesn't operate, check all fuses and inspect any/all wiring connections.

Good luck

The tank is under the front wheel arch. The best way is to remove wheel and splash guards and you will be able to access the tank from the engine bay and the wheel arch. Check first that the leak is not from where the pipe connects to the screen wash pump or the grommet that holds the pump in place in the tank. these would seem more likely than a split tank. The pump justs twists out of the grommet - its tight but not impossible to remove and replace if the pump has a fault on its body or pipe cionnections.
Hope this helps. good luck.

Is your wiper fluid level good?Look for leaks at pump,it's connected to container,also check your hoses leaving pump to windshield,could be loose or binding.

Could be a couple of things ,,,, If the washer resevoir frooze in the recent past it could have split the motor/bottle or hoses attached, it may also be the anti return valve (Y shaped) on the hose work split and causing a drip !

The most common problem I find in this season, is having summer 32 deg. F freezing windshield wiper fluid in the tank rather than -20 deg. F freezing windshield wiper fluid.

Try to warm up the car by parking it in a heated garage until the windshield wiper fluid thaws. Then, try to use it all up, and add the 'winter' vs. the 'summer' formula of windshield wiper fluid.

If this does not solve the problem, the pump might be burnt out, in my experience.

You should hear a humming sound as you depress the button for windshield wiper fluid inside of the car.

Good luck on this repair.

it's likely the tiny motor/pump located at the bottom of the tank that has failed. to confirm this have some turn on the washer fluid switch and test for voltage at the pump. there are several aftermarket pumps you can use as a replacement.
