    I have the same problem as Russell had with a 1996 Dodge Caravan. The wiper does not work except in the washer mode.
    Looking for a solution.

    I did as instructed, the result is wipers work at one speed, reg. at one position only, thanks.

My solution is as follows: Place a 1K-OHM resistor (Radio Shack Part # 271-1118) between the orange/white stripe wire (power) and the green/yellow stripe wire of the mullti-switch terminal block of the steering column. This provides the speeds - normal and intermittent speeds but not high wiper speed. Less than a $1 solution instead of the costly BTM replacement.

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.

    Wiper issues only work on high but work very slow


    with engine running and not.?
    front or rear wiper,?????
    toss dice, land on front......( 50/50 odds)
    it's a network now, no more old style, point to point one wire for every thing on car and a ton of copper to match.
    first test all fuses, then scan it.
    or it will get expensive fast guessing.
    the Switch bank brain under the wiper stalk
    sends what you did, on to the LIN bus network,
    The switch there does not actually drive lamps.
    its just a digital switch, (some are 3 level logic)
    The switches on some use a bank of internal resistors to tell the switch bank what you did.

    this LIN data stream, is sent to the cluster brain
    and also to the TIPM brain.(Allen Turing brains)
    the cluster responds for many actions, taken and shows you what you did (EG) for blinkers, flashes the cluster TURN lamp. in same.
    Wipers front.
    the command for wipers are sent to the TIPM
    this device, runs (DRIVES) a huge number of things on the car. (ask for schematics, I have it in pdf forum now,)
    Totally Integrated power module. or TIPM
    It drives the wiper motor using internal high powered electronics. Direct drive,..
    It also senses the wipers location called the sense wire.
    The TIPM brain, has complex logic to do all that
    it gets many commands to do, (fast ,slow, intermittent wipe) and via TIPM computer memory instructions,
    does the job.with pure software. inside.
    the wipers can fail for many reasons besides simple mechanical jam or a cut wire.
    1: fuse blown to any of those module. check them all if you are SAVVY!
    2: TIPM bad,
    3: TIPM power supply pin too low, say car battery is 10v ( are head lamps dim,, hummmmmmmmmm)
    4: TIPM programming bad. (scrambled brain, needs re-flash)
    5: CAN bus or LIN bus, noise, or gross collisions of data on that vital bus. (only scans work here)

    IF all fuses are good we scan it .
    as always , we check battery voltage first.
    with out fail, and listening to the starter motor.
    if the starter is dead or weak , we want a strong battery to make all this complex electronics in the car work.
    A $10 voltmeter and you know know, battery is above 12.6vdc rested, key on, engine off.
    start engine and it goes above, 13.3vdc.
    That same tool i can test all fuse. ask.
    end comments.

    FSM page:
    the first page states (QUOTE)
    The most reliable, efficient, and accurate means to diagnose the front wiper motor or the electronic controls and communication related to front wiper motor operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
    NOTE The front wiper and washer switches are integral to the right multi-function switch. The right multi-function switch is hard wired to the left multi-function switch/Steering Control Module (SCM), which communicates with the ElectroMechanical Instrument Cluster (EMIC)/Cab Compartment Node (CCN) over the Local Interface Network (LIN) data bus.
    Before performing any of the following tests, determine whether the other functions of the right and left multi-function switch/SCM are operational. If only the right multi-function switch functions are inoperative, test and repair the right multi-function switch or the jumper harness between the right and left multi-function switches before attempting to repair the Front Wiper and Washer System. If both the right and left multi-function switch/SCM functions are ineffective, diagnose and repair that problem before attempting to repair the Front Wiper and Washer System. end quotes.


    what's MORE?
    what is missing is a block diagram, here ill make one so we can all learn....


    Binary switch stalk. via 7 pin connector.
    to:
    SCM module (steering control module)
    to: (i guess the SCM is the Bank switch brain)
    the LIN>CAN network, (the SCM sends digital commands to)
    to:

    if you scan it and see errors from SCM to TIPM
    that needs to be corrected first.
    garbled bus data will make the TIPM go nuts.

    That ground bad theory fails. because...
    the motor uses Ground G112
    if that wire fails you get vast numbers of failure from 10 majors. including oxygen sensor 1/2
    so it;'s not G112 bad.
    the motor has fast winding and low speed.
    and a common ground. and a sense wire.

    never skip scanning the car, or its all like a dog chasing his tail.
    Battery not discharged, (you never said car runs)
    fuses all good, (means tested)
    scanned and not DTC errors. (i bet yes errors)
    there 7 pages for the whole can/lin bus.

    but this one is switch banks.
    one tricky aspect of this, is the cluster
    I think translates this wiper data commands from the LIN bus and then rebroadcasts to to the CAN-BUS. that he TIPM uses.that means.
    so error are both buses are important.
    this is the LIN-bus, the cluster retransmites the commands do the CAN-BUS. so if cluster is dead
    that kills those commands,... out.bound. see?
    tricky, i told you.

    Which fuse controls front windshield wiper pump


    Do the wipers work ? Fuse for wipers is same as washer pump .
    Principles of Operation
    The wiper motors receive inputs from the following:
    • Multi-function switch
    • Powertrain control module (PCM)
    • Ignition switch
    • Smart junction box (SJB)
    The following components are integrated in the wiper motors:
    • Windshield wiper motor module
    • High/low speed relay
    • Run/park relay
    • Washer pump relay
    • Park sense (Hall-effect sensor)
    Washer System
    The windshield washer and the rear window washer are activated by the internal wiper motor modules when it receives a ground from the multi-function switch between the washer inputs. Depending on the correct ground, the internal wiper motor modules activate either the windshield washer or rear window washer relays (internal) by grounding the respective relay coil. When either module is activated, it connects voltage to the washer pump while the deactivated module provides ground to the washer pump. In this manner, voltage polarity is reversible to achieve directional change of the washer pump and washer fluid.

    Does your expedition have programmable/recall memory option for seats an mirrors ?
    Driver Seat Module
    The power driver seat and power exterior mirrors are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option.
    On the Expedition Limited, the power fold exterior mirror option is controlled by the DSM. Before running a self-test or retrieving codes, the power fold switch must be inactive for at least 30 seconds.
    This is a complex vehicle , electronics , control modules an serial data communication networks. You mite be better off taking it to the dealer or some other repair shop . There could be DTC'S - diagnostic trouble codes stored in the SJB - body control module !

    I have a 2007 mustang an the wipers wont turn off I had 2 pull the fuse to turn them off can u help me


    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 !

    I need to know how to replace my turn signal switch on my steering wheel my windshield washer turner broke off so either I need to know how to fix the windshield washer switch or just replace the whole...


    The turn signal switch or in Ford terms "multi-function" switch is easy to replace if you are mechanically inclined. Lower the steering column "tilt" adjustment for easier access. Remove the lower panel (below the steering column). Remove the three screws from the plastic column covers that surround the multi-function switch. Turn the key to the run position, then from the bottom side of the column, use a very small pocket screwdriver, allen wrench or similiar tool to push up on the ignition cylinder release pin. The hole is located just below the cylinder. With the pin pushed, pull out on the key and cylinder. Next seperate the two cover halves and you will see the complete multi-function switch. remove the two attaching screws, remove the electrical connectors and replace the switch. Replace all removed components and you're done! You can purchase the switch at most auto parts stores, ford dealers or ebay. Feel free to ask if more information is needed and I appreciate a vote of four thumbs up. Good luck!

    Both headlights quit working simotaneously


    There are just (3) possible reasons for this:
    (a) your headlight switch has failed, or
    (b) your headlight relay has failed.
    (c) Fuse 1 (25 Amps) has blown

    The headlight relay and fuse 1 are located (I think) in a fuse/relay block under the hood.
    The headlight switch is part of the "Multi-function Switch" on the steering column.

    Here's how to replace the 2001 PT Cruiser multi-function switch:

    archaeology_27.jpg
    Multi-Function Switch Removal & Installation
    1. Open the hood.
    2. Disconnect and isolate the battery negative cable.
    3. Remove both upper and lower steering column shrouds.
    4. Disconnect both posi-lock harness connectors at the rear of the multi-function switch.
    5. Remove multi-function switch mounting screws and remove switch from vehicle.




    To Install the new multi-function switch:

    Note:
    If replacing the multi-function switch, the combination flasher and windshield wiper/washer switch
    must be transferred to the new multi-function switch.

    1. Remove the two Torx(R) screws retaining the wiper/washer switch, place next to the new
    multi-function switch and install two screws.
    2. Place switch into place and install mounting screws. Torque multi-function switch to column
    retaining screws to 27 inch-lbs. (3 Nm).
    3. Connect both posi-lock harness connectors at the rear of the multi-function switch.
    4. Install both upper and lower steering column shrouds.
    5. Connect the battery negative cable.
    6. Close hood.
    7. Verify vehicle and system operation.
