How to turn on and off rear windshield wipers

"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."

Rear Wiper/Washer System Components
The rear wiper/washer system consists of the following components:
• Rear wiper/washer switch
• Window wiper module-rear
• Window washer pump-rear
• RR WIPER 15A fuse
• RR WPRB 25A fuse
Rear Wiper/Washer System Operation
The rear wiper module controls rear wiper motor operation. Battery voltage supplied to the module is used to operate the wiper motor in all modes and to return the rear wiper arm to the park position after the ignition is turned off. Accessory voltage supplied to the rear wiper/washer switch is used to supply the rear window wiper and washer switch signal circuits. In wiper switch positions 1 and 2 the wiper switch signal circuit voltage level to the wiper motor module determines the wiper motor delay interval. The rear window washer pump supply voltage circuit is used to provide the operating voltage for the rear washer pump for as long as the rear washer switch is pressed. The rear window washer switch signal circuit is used as a wash signal to the rear wiper motor module to operate the wipers during the rear wash operation.


Did you replace the rear wiper module ?

Replacing parts just to replace them wont fix a bad wire or part. Better to use a voltmeter and ohn meter to check if your getting power to the wires. You may have a bad connection or bad switch on the column for the pumps. Without checking the circuits it will behard to tell what it is thats wrong. Find a wiring diagram and trace the wires and components.

Did you check the wiper relay's in the under hood fuse box ? There are two ,wiper run/park relay & wiper high low relay ! Also ,did you check fuse's ? fuse # 11 - 30amp location cental juction box . The wiper switch is a input to the GEM module . Generic electronic module . The module in most cases isn't the problem ! Learning how to test these electronic systems is , people do not know how to test so they just replace parts . What they should do is take the vehicle to ford certified Technician who has the knowledge and testing equipment to find an fix it .

The generic electronic module (GEM) receives inputs from the following:

• multifunction switch
• anti-lock brake control module (vehicle speed signal [VSS])
• ignition switch

The GEM uses these inputs to control the outputs to the following:

• windshield wiper high/low relay
• windshield wiper run/park relay
• windshield washer relay
• rear wiper motor relay
• rear window washer relay

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 wipers only worked occasionally. ... My 1998 dodge ram wipers only work on high will this help me? thanks.... Express van. you have to take out the motor and the transmission from under the front of the van..

Here are some more common problems.

• Motor:

The wiper motor is commonly replaced and was often not the problem. Don't replace the motor yet. maybe it's not the motor. It could be a fuse or something at the wiper switch. The wiper motor has two windings, fast and slow. The wiper switch sends a ground signal to each motor winding. More often, there are problems with the relay, or at the wiper switch, or in the cable to the motor.

• Windshield Washer:

Don't be too quick to replace the washer pump. The problem is often just a clog in the sprayer heads. You can clean out the sprayer holes with a needle, some have two holes, so look closely. Hope this helps.

why do you think the motor still works if the wipers don't move? Can you hear the motor run or can you see a little movement when you turn the switch on?

What happens when you activate the washers?

go to a salvage yard that allows you to remove the parts yourself. Then you can see how the motor and linkage assembly comes out.


don't have 1983 info, but here is 1994:
