Fill rear washer fluid - Acadia GMC Cars & Trucks

It operates from the same tank as front washers.

Yes it does and the washer fluid reservoir under the hood is for both the front and rear. The following is a diagram of the washer pump and hoses so you can check for operation or leaks.

The same tank that holds the front wiper washer fluid holds the rear. If your rear washer is not working, it could be one of 2 things.....

1- your washer fluid tank is low. Most car manufacturers design the tank so the rear washers stop getting fluid first to remind you to fill the tank.

2- there is a clog in your rear washer system or the pump is not working. Your problem sounds like your pump is working, so first top off your washer fluid tank, then if after about 30 seconds of trying (it takes a while to get back there), try to first unplug the rear washer by scrubbing with a toothbrush and hot water. Next, follow the hose to see if it is pinched somewhere or broken.

Find under the hood botle/container with cap like this

There is only one container for washer fluid, and for front and rear whiper fluid goes from ths same container witch is under the hood.
If your front washer is working and rear doesnt than it's problem with fluid pump or line from the containet to the rear wiper is damaged or disconected.

All washer fluid comes from the same reservoir. If your not getting washer fluid to the rear washer, it could either be a plugged or broken washer fluid line, or rear washer fluid pump.

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.

Uses 1 washer jar up front for both front and rear. Hope this helps

This comes directly from the owners manual.
Checking and adding washer fluid for the liftgate
Washer fluid for the liftgate is supplied by the same reservoir as the front windshield washer.

U may have a kinked supply line at the tailgate.

My front and rear washers are both connected to the same washer fluid tank.

there shouldn't be any rear washer fluid reserve for you back window there's only one reserve and that's under the hood which controls the front and back. but also you can call your local dealer and ask them.
