They (the wiper motor and mechanism) are underneath the cowl vent screen.

To replace the motor and mechanism:
1: Turn the ignition to the on position with the wipers at low speed. When the arms are point straight up, turn it off.

2: Use a small screwdriver and pry the plastic caps from the wiper arm mounting ends.

3: Disconnect negative battery terminal

4: Remove the small retaining nup from each wiper arm, then the arms.

5: Remove the cowl screen by turning the eight plastic retainers 1/4 turn counterclockwise. Next remove the six screen retaining clips. If it's a 2000 or later, remove four bolts that secure the arm monting bar so that you can access the wiper motor.

6: Disconnect the electical connections and remove the four screws that secure the motor and mechanism to the cowl, and take out the motor-mechanism assembly.

7: The drive mechanism isn't serviceable, but the motor can be replaced. Remove the operating arm nut from the motor shaft, and remove the three screws that hold the motor to the drive mechanism.

8: Reinstall the wiper mechanism into the cowl and connect the electrical connectors. (Before reinstalling the wiper arms and blades, turn the ignition to the on position and turn the wiper switch to either LO or HI, then turn the wiper switch Off. This lets the motor cycle to the park position thus avoiding damage to the arms and drive mechanism).

9: Install the wiper pivot arms, ensuring the blade tips align with the park reference mark at the base of the windshield.

10: Ensure that your wiper blade is fully seated on the wiper arm before operation the wipers.

11: Finish up the reverse way you began.

WHERE IS THE WIPER/WASHER FUSE LOCATED ON 2007 PONTIAC TORRENT


In the under hood fuse box , should have diagram inside the lid . Front wiper's or rear ? Front fuse # 36 - 25 amp. Plus Two relay's PCB hi and Wiper PCB relay . Wouldn't think this being fuse problem . Wiper switch , motor etc... The wiper's are control by a computer . BCM - body control module .

The windshield wiper/washer system consists of front and rear wipers. The front and rear wipers are operative when the vehicle is in accessory or run. The front wipers have 4 different modes: Mist, Intermittent, Low, and High. When the front wipers are in the intermittent mode, there are 5 delay modes to chose from, commanded by the windshield wiper washer switch through the body control module (BCM). The rear wipers has an only one mode.

If the fuse is bad , could have a short to ground or wiper motor pulling to much current (amps) . Fuse's don't just blow for no reason ! Could also have DTC'S - diagnostic trouble codes stored in the BCM .
DTC B3715
DTC B3873
DTC B3875
DTC B3922

DTC B3715 02: Front Wiper Relay Drive Circuit Short to Ground
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.
The BCM controls the windshield wiper motor through two output controls, controlling two different PCB relays which control the desired wiper speed, high or low.

The PCB relay's are non- servicable , replace fuse box . Soldered in Your best bet mit be to take it to a qualified repair shop .

How do I find out if the wipers on my 2006 H3 Hummeris on a relay?


The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Body control module (BCM)
• Wiper micro relay
• Wiper 2 relay
• Wiper diode
• Windshield wiper motor
• Windshield washer pump
• Windshield washer nozzles
• Windshield washer solvent container
• Windshield wiper arm and blade assemblies
• Windshield wiper transmission
• WIP/WASH 10A fuse
• WIPER 25A fuse

Wiper/Washer System Description
The body control module (BCM) controls wiper motor low speed operation. The washer pump and high speed operation are controlled directly by the wiper/washer switch. The windshield wiper/washer switch supplies voltage on the signal circuits to the BCM for windshield wiper/washer operation. When WASH, MIST, DELAY, LOW, or HIGH is detected, the BCM energizes the wiper micro relay by suppling voltage to the relay coil. This allows battery voltage from the WIPER fuse to flow through the relay switched input then through the contacts and out the relay switched output to the wiper 2 relay switch contacts. Since the wiper 2 relay switch contacts are normally closed to the low speed circuit of the windshield wiper motor, the motor will operate at low speed.

Low Speed Operation
When the wiper switch is in the Low position, voltage is supplied through an internal resistor to the signal circuit. The body control module (BCM) monitors the windshield wiper switch signal 1 circuit, and energizes the wiper micro relay which will operate the windshield wiper motor. The wiper motor will operate at low speed, since the wiper 2 relay is de-energized. Low speed can also be commanded with a scan tool, by commanding Wiper Relay Cmd. ON and OFF. Refer to Scan Tool Output Controls .
High Speed Operation
In the High position, the windshield wiper/washer switch supplies voltage to both the wiper micro relay and wiper 2 relay coils. This energizes both relays and allows battery voltage from the wiper micro relay switched output to the switched input of the wiper 2 relay through its contacts and out the switched output of the wiper 2 relay to the high speed circuit of the windshield wiper motor. The windshield wiper motor will operate at high speed. During high speed wiper motor operation the wiper switch signal circuit is at the low speed signal voltage, and the body control module (BCM) supplies redundant voltage to the wiper relay via the wiper diode.

This info is out of hummer factory service manual !

Looking for the fuse for the wiper motor 2008 chevy impala


WPR fuse 25amp under hood fuse box .
Wiper/Washer System Components
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Body control module (BCM)
• Wiper PCB relay
• Wiper high PCB relay
• Windshield wiper motor
• Windshield washer fluid pump
• Windshield washer fluid level switch
• WPR fuse 25 A
• WSW fuse 10 A
This is more then likely not a fuse issue !!!!!!!
Low Speed Operation
When the wiper switch is in the low speed position, ground is applied through the switch internal resistor and the wiper switch low signal circuit to the body control module (BCM). In response to this signal, the BCM energizes the WIPER PCB relay by applying battery voltage through the wiper relay control circuit to the coil side of the relay. This allows battery positive voltage from the WPR fuse to flow through the switch input side of the WIPER PCB relay and out to the switch input side of the WIPER HIGH PCB relay. Since the wiper high relay is de-energized and its switch contacts are normally closed to the low speed control circuit of the windshield wiper motor, the motor will operate at low speed.
Wiper motor low speed operation and the wiper PCB relay can also be commanded ON/OFF by using a scan tool. Refer to Control Module References.
The PCB relays mentioned above are soldered right into the circuit board inside the fuse/relay block under the hood . There are alot of reasons for the wipers not to work ! The fuse could be blown but fuse's don't just blow for no good reason , short to ground , low resistance high current flow etc.... Intermittant !

Power and Grounds
With the ignition in the ON position, accessory voltage is supplied through the 25A WPR fuse to the WIPER PCB relay, the WIPER HIGH PCB relay and the WS WASH PCB relay that are all located in the underhood fuse block. Refer to Wiper/Washer Schematics.
G200 provides ground for the windshield wiper motor and the WIPER PCB relay. G100 provides ground for the windshield washer fluid pump and the windshield washer fluid level switch.

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 !

Windshield washer pump relay location


Try to trace the rubber hose to the washer spray on the hood.
That should lead you to the washer pump. The relay should be in that area. Sometimes it's with the fuses under the hood.
Hope this helps.

Washer doesn't work and I can't hear the pupmp motor working.


The windshield washer pump is part of the windshield wash reservior.
There is an electrical connector located on the bottom of the reservior.
That is the pump .
If the pump is not in the reservior. I would just trace the washer fluid lines from the sprayer on the vehicle back to the pump. The lines just might lead back to the reservior for the windshield wash solution. Then you will have confirmed the pump is in the reservior.

You may have to get a new reservior. The pump might not be seperate item, I am not 100% sure on that.

I also would double check the fuses and any relays related to the washer pump.

Finally, I would check the washer switch if you replace the pump and still is not working .

Good luck

Winshield washer motor does not run


These days, most windshield washer pumps are mounted to the bottom of the washer fluid reservoir. Where’s that, you ask? Well, inner+fender+w+text.jpgyou know that spout you pour the fluid into—the one that disappears into nowhere? Well, the reservoir is actually 2384f71.jpglocated inside the front fender between the bumper and the front wheel. To replace the pump, you will have to jack up the vehicle, remove the front wheel and then remove the inner fender liner.
