I have seen a simular fault which ended up being the intermittent wiper relay was full of water from water collected in the airconditoners evaporator tray.
The water has problems escaping this tray & when you go around the corners the water rans out onto your feet & the intermittent wiper relay is mounted down the side of the transmission wall & gets soaked along with the carpet.
I suggest you find the relay, remove it check the inside of it for water damage. If stuffed replace it & also suggest to check your evaporator's tray & rubber S bend drain for obstructions. I think this is a design fault in all 240s.
Another fault I have seen with the wiper motor is it not running too well with excessive noise, due to water getting into the motor through the 2 mounting clips on the round part of the motor casing to the casting. There are 2 small slots which allows water into the motor.
I suggest remove the wiper motor by removing the cir clip & or nut under the dash board connecting to the arms, Then the 3 x 10mm bolts & carefully pull the wiper motor apart don't loose the 2 angled clips & screws, clean & re grease the motor & try not to damage the maganets or over tighten the 2 screws & re assemble in reverse order.

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.

2003 Pontiac Montana wipers not working how to fix


First you need a wiring diagram, free at http://www.bbbind.com/free_tsb.html Then you need a DVOM - digital volt ohm meter to test the circuit . Then if your not familiar with automotive electrical systems testing ,go on youtube an check out Electric Testing Techniques You Need to Know Also having a factory diagnostic trouble shooting chart would also be usefull . You could just start replacing parts , you mite get lucky . The wiper motor is a high fail part , so is the switch ..You could find the fuse is blown ! But fuse's don't usually blow without a reason . Short to ground , low resistance . ( high current flow) Also knowing how they work and what all is involved in making them work.
The Wiper/Washer System consists of the following components:
• Windshield wiper/washer switch
• Windshield wiper motor module
• Windshield wiper motor
• Windshield washer pump motor
• FRT/WPR/WSHR 25A fuse

Wiper/Washer System Operation
The windshield wiper motor module is part of the windshield wiper motor cover and controls wiper motor operation. The windshield wiper motor is a 2 speed motor and is operated at low speed in all modes except HIGH. The accessory voltage supply circuit to the windshield wiper motor assembly is used to operate the wiper motor in all of the low speed modes. The accessory voltage supply circuit to the windshield wiper/washer switch is used to supply the windshield wiper switch signal circuits and the wiper motor high speed circuit.
When the wiper/washer switch is in the LOW position voltage is supplied through a 24K ohm resistor within the switch to the windshield wiper switch signal 2 circuit, and accessory voltage is supplied to the windshield wiper switch signal 1 circuit. The reduced voltage from the wiper switch signal 2 circuit and accessory voltage from the wiper switch signal 1 circuit causes the wiper motor module to close the wiper motor accessory voltage supply circuit to the wiper motor low speed terminal.
Windshield wiper/washer system MIST operation is identical to LOW operation except that the MIST switch is a press and release type. When the wiper switch is moved to the MIST position and released, low speed wiper motor operation is started and will continue until 1 cycle is complete. If the wiper switch is moved to the MIST position and held, the windshield wiper motor will operate in the LOW mode until the switch is released.

Don't the wipers work in any mode ?

My wiper motor only works on high and stops were ever the wipers are at. And the washer motor doest #39;t work


Low Speed Windshield Wipers
Low speed is activated when the multifunction switch supplies a specific ground to the speed inputs of the windshield wiper motor module. The windshield wiper motor module then supplies ground to only the windshield wiper run/park relay coil, activating it. When the windshield wiper run/park relay is activated, the deactivated high/low relay connects voltage to the windshield wiper motor low input activating the wiper motor. The windshield wiper motor module continues to operate the windshield wiper motor in the same manner as in high speed, but in low speed with the wiper motor connected to the low speed input.
Washer System
The windshield washer is activated by the internal wiper motor module when it receives a ground signal input from the multifunction switch. Dependent on the switch selection, the internal wiper motor module activates the windshield washer relay (internal) by grounding the respective relay coil. When the relay is activated, it connects voltage to the washer pump while the washer level switch provides ground to the washer pump.

    Circuit/System Description
    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 windshield wiper motor park operation is controlled by the BCM. The BCM recieves an input from the park switch to determine wiper blade position. When the wiper blades are at the bottom of the windshield glass in park position the wiper park switch will open and the circuit will be pulled up to B+ by the BCM. The park signal will be pulled to ground by the wiper motor park switch while the wiper blades are not in the park position.
    The BCM controls the windshield wiper motor through two output controls, controlling two relays which determine the desired wiper speed, high or low
    Diagnostic Trouble Codes (DTCs)
    The body control module (BCM) monitors the voltage on the windshield wiper switch signal 2 circuit for diagnostic purposes. If the circuit is shorted to voltage while the driver is commanded OFF, the BCM will store DTC B3715. If the circuit is shorted to ground while the driver is commanded ON, the BCM will store DTC B3715. Refer to DTC B3715.

    The windshield wiper motor is a smart wiper motor with an integrated electronics module. The internal components of the motor are the high/low relay, washer pump relay, and the run/park relay and associated electronics.
    The windshield wiper motor receives its inputs from the windshield wiper/washer switch. These signals are ground reference signals. When the switch is placed in different positions, various input signals are selected and sent through circuits to the motor. The windshield wiper motor module identifies these selected input signals and activates the motor to the selected function.!
    Your probably going to need a new wiper motor ! ! ! But you should always test before replacing parts !

    My automatice wiper won't turn off on thier own


    It has auto wiper control. Yank your wiper stick 1 notch down. The windshield should be free of rain droplets or else it would think it is still raining and operate it in auto mode. In auto mode it will shut off when it doesn't sense rain droplets on the windshield or removing the key from the ignition. Once it is off, it can only operate in auto mode by moving the lever 1 notch up while raining. Yours must be in the 1st speed manual selected position of the lever. Every time the ignition is switched on the wiper operates regardless until key is removed from the switch.

    WIndshield Wipers only start on fastest speed


    There are three things involved in wiper operation, switch, the delay circuit board and the motor. If you select winshield wash do the wipers operate normaly? if this is the case then the motor works and delay is operating < not a guaranty on delay but it does say the circuit is operating.If wash cycle does not work then circuit not working< could still be switch causing this> if you know someone or you yourself can remove switch it needs to be ohmed to know that it is operating and if it is then voltage during operation in all settings needs checked at wiper motor.If no voltage found in inoperable settings then delay is not working.While investigating problems like this always inspect wiring as you check from point to point because could be damaged wires as well.
