Your windshield wiper's are computer controlled by the BCM - body control module . The wiper switch is an input to the BCM , which energizes two different relay's to turn on the wiper's . Taking the vehicle to a qualied repair shop an having diagnostic's run would be your best bet , unless you have a professional scanner that can read DTC'S - diagnostric trouble code's in the BCM !
DTC B3715 00: Front Wiper Relay Drive Circuit
DTC B3875 00: Wiper High Speed Relay Circuit
DTC B3922 00: Front Wiper Function Select Circuit
This is always the first step in the diagnostic process . An if you do not know how they work ,reading factory service manual info. should be done .
The body control module (BCM) controls the wiper motor based on input from the windshield wiper washer switch. The BCM monitors the wiper washer switch through three separate signal circuits and a ground circuit. The windshield wiper switch high signal circuit is used to determine high speed wiper operation, the windshield wiper switch low signal is used to determine low speed, intermittent, and mist operation through the use of a resistor ladder, and windshield washer switch signal circuit is used to determine washer operation.
Your best bet , take it to a qualified repair shop.
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 !
2008 Saturn Vue rear wiper blade: Pop off the cover over the bolt that comes out of the rear window. Unscrew the nut. Now you can remove the assembly. Give the old wiper a tug and pull it out. Snap in a new 11-inch wiper. Replace the assembly, bolt and cover.
there are two motors ,one runs the front and the other runs the rear. check the connection at the front washer pump sometimes it gets dirty and doesnt make a good connection, if the connection is good and clean then replace the washer pump, here a picture of it. hope this helps
I have had the same problem. Dealer said it was a corroded wiring connection. They changed it and problem was fixed. I suspect a lot of corrosion problems will occur eventually on my Saturn including the rear wiper wiring, which has gradually stopped working.
I have the same problem, Noticing that my 2006 Saturn Vue, 5-speed becomes extremely hard to shift
gears when the weather is cold. (Temps range from 20-43). Has been colder in the last month. What could this be?
also side note: Our windshield wiper spray doesn't work on front window but work on back. They both started about the same time when the temps dropped to single digits. Dont know if that had any causes.
two separate switches normally have two separate fuses.voltage drop test wiper ground.also check switch output at different speeds. this vehicle may have control module and/or relay by itself or with the module. if output is at switch,intermediate component is the problem.
The easy part is you just need the latch for the liftgate. The hard part is getting to it and opening the liftgate to replace the latch. You should be able to pull the liftgate trim off most of the way with the gate closed and try to manually actuate the latch to open the gate. You may have to go so far as breaking the latch from the inside to open the gate and then replace your latch.
