In my 2007 Saturn Vue there is what I think is an air pump which is cracked that one port is not connected to anything.


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 !

The windshield washer fluid isnt coming out for


Yes there are two pumps located in the wiper fluid reservoir. If your in a bind, you can switch the plugs and small hose that go to them because they are both the same. The upper pump operates the back, and the lower pump operates the front. The back won't work until it gets replaced, but it beats driving backwards.

MY REAR WIPER AND WASHER DON'T WORK


Check your fuse...for the rear wipers...Now as for the fluid..make sure it's full, because it may not be coming from the front one..you may have a jug located in the back..And if your fuse is good, and you have power to the moter, and the washer fluid pump....Then the washer fluid pump is bad...And you may need a Rear windshield wiper motor...

The rear wiper on my '99 model exped isnt working ,ford global says its the motor and it will cost me P13k . any one who can help me find a mechanic do some repair on this?


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.
  1. Visually inspect for obvious signs of mechanical and electrical damage.
