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.

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.

    Wipers dont work


    This is a complex wiper system . Here are all the components involved !
    The Wiper/Washer System consists of the following components:
    ?€¢
    Windshield wiper/washer switch


    ?€¢
    Body control module (BCM)


    ?€¢
    Wiper 1 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


    ?€¢
    WIPER/SW 10A fuse


    ?€¢
    WIPER 25A fuse


    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.
    It would be best to have a factory scan tool to diagnose this problem . it would make it easier anyway .

    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.

    OFF/Low/High Speed
    • Has a two-speed, permanent magnet, three brush electric windshield wiper motor .
    • The windshield wiper motor has a brush rigging that permits selection of low or high speed.
    • When the turn signal and windshield wiper switch is in the LO position, the common brush and the blue/orange wire brush are used, and the windshield wiper motor operates at low speed.
    • When the turn signal and windshield wiper switch is in the HI position, the common brush and the white wire brush are used.
    • In HI position, electric current will bypass a portion of the armature winding causing the windshield wiper motor to operate faster.
    • When the turn signal and windshield wiper switch is moved to the OFF position, the windshield wiper motor will continue at low speed until the park switch outer contacts open.
    • When the park switch contacts open, the windshield wiper motor stops in the park position.
    Interval
    When the turn signal and windshield wiper switch is in the interval position:
    • The wipers make single wipes separated by pauses.
    • The rotary switch is on the end of turn signal and windshield wiper switch .
    • The length of the pause can be set from approximately 1 to 17 seconds.
    • Length of pause decreases as the rotary switch is rotated away from off.
    • Length of pause increases as the rotary switch is rotated toward off.
    While in the interval wiper mode:
    • It is normal to hear a slight click at the beginning of each on/pause cycle. NOTE: When using interval wipers, the first wipe may not occur until after a pause of up to 17 seconds.

    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.
