Is yours still working ?
Mine works but doesn't cancel any more.
It is covered by the Premium Care for replacement.
I just have to get it into the dealer.

[ctrlraven]

Mine had a mine of their own. Replaced the motor, they go on for about 10-15 seconds then stop and allow me to have control again but they only work at one speed (close to high) and turn off wherever I turn them off, they do not return to resting position. So only other thing to replace is the switch now.

Part number 3w1z13k359aaa was superseded by part number 3W1Z13K359BAA. MSRP ~$60 - Disc ~ $43.
This info is dependent on my reading my book correctly.

If you have FORD premium care, then yes it should be covered with whatever deductable you have.

[ctrlraven]

Figured I would call and price it.

Liberty Ford in Baltimore $119.89
Thompson L/M in Baltimore $100.00
Apple Ford in Columbia $99.91
Safford L/M in Silver Spring $99.91
Miller Bros. Ford in Ellicott City $88.00
Academy Ford in Laurel $73.47 (old dealer I used to work for)

My mouth about dropped when I heard Liberty's price. Only Academy and Safford asked about my build date where the rest didn't.

When I get some time Wednesday during week sneak out and go order it and pick it up Thursday when their parts dept is open late.

Try contacting Ray "TheDealer", a supporting vendor here...Northeast L/M in Philly...he offers discounted prices to mm.net members.

FUDGE!

So I just hooked up the new switch and before I put anything back together thought I would test it out...........still have the problem. :mad2:


So what do I have left to replace now? Anyone have any ideas? If it is something else and works after that I am going to put my old switch back in and if it changes anything, if not then I will have a brand new switch for sale I guess.

[Breadfan]

How about that pigtail? Maybe the reason they replace it is due to corrosion inside it somewhere that isn't obvious when taking it apart???

[ctrlraven]

Plug actually looked very clean and I cleaned it some more. After replacing the motor made the biggest difference cause it allowed me to at least control the wipers.

NOTE: During installation, it is necessary to pull the locking tab out to its full open (unlatched) position and hold while assembling the pivot arm onto the mounting arm and pivot shaft. Align the key on the pivot arm head with the keyway on the shafts. This will make sure the pivot arm is correctly aligned. If necessary, the keyway can be removed. To adjust wiper pivot arms, refer to Windshield Wiper Blade and Pivot Arm Adjustment (file:///C:/tpsreposit/useni4/S3A1G004.htm)in this section.
To install, reverse the removal procedure.

Hooked up the old motor with the new switch installed and still did the same thing so I can rule out the wiper motor and the switch. I guess what's left is the pigtail even though it's clean and making proper contact.

Is the wipers tied into another system?

Don't the wipers tie into the LCM as wipers on will cause the headlights to come on?

[ctrlraven]

I was thinking they tie into the LCU but as far as I know we don't have that feature on the cars. My lights only turn on when I turn them on or at night when the light switch is left in auto.

I have a sneaky feeling it's something like the LCU. Are they costly?

My car's lights turn on when my wipers have been on. I notice it from time to time.

When mine went berserk, my lights came on as well, and no position on the headlight switch would turn my lights off. I've been driving my 'stang so I haven't messed with the wipers on my MM much in the last week.

Did your headlights come on after awhile when your wipers went nuts?

No clue what the LCU costs...wonder if there's a way to test though.

Principles of Operation
The windshield wiper motor receive inputs from the following:

multifunction switch
lighting control module (LCM)
ignition switch
battery junction box (BJB)
central junction box (CJB)The following components are integrated into the windshield wiper motor:

windshield wiper motor module
high/low speed relay
run/park sensor (Hall effect)
washer pump relayHigh Speed Windshield Wipers
High speed is activated when the multifunction switch supplies ground to the windshield wiper motor module inputs. The windshield wiper motor module then supplies ground to the run/park sensor and high/low relay coil, activating the relay with voltage supplied from the ignition switch (RUN/ACC) through the central junction box (CJB). When the windshield wiper motor module receives voltage from the run/park sensor, it removes ground from the run/park sensor, deactivating it. The windshield wiper motor continues to operate from voltage connected through the run/park sensor until the Hall effect senses the magnet in the motor. When the Hall effect senses the magnet in motor the windshield wiper motor returns to the park position, the internal run/park sensor grounds the windshield wiper motor module input and the windshield wiper motor module removes ground from the windshield wiper high/low relay coil, deactivating the high/low relay and windshield wiper motor. The windshield wiper motor module continues to cycle the windshield wipers until the inputs from the multifunction switch are changed from the high speed position.
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 windshield 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.
Intermittent Speed Windshield Wipers
The intermittent wiper speed is activated with grounds controlled by the multifunction switch inputs to the windshield wiper motor module. The windshield wiper motor module then activates the windshield wiper run/park relay coil and switches voltage through the windshield wiper high/low relay. The high/low relay remains deactivated, supplying the voltage to the wiper motor low speed input and activates the windshield wiper motor. When the windshield wiper motor module receives the grounded input, the motor continues to operate until Hall effect sensors senses the wiper motors magnet, which turns off the run/park sensor output to the windshield wiper run/park software, deactivating the relay and disconnecting voltage to the wiper motor. The windshield wipers remain parked until the windshield wiper motor module completes a time-out and then repeats the intermittent windshield wiper cycle.
Washer System
The windshield washer is activated by the internal wiper motor module when it receives a ground from the multifunction switch between the washer input. Dependent on the correct ground, the internal wiper motor modules 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.
Default Mode
The windshield wiper motor defaults to this mode when the run/park sensor does not sense the hall effect magnet inside wiper motor. This can be caused by obstruction of the windshield wipers or a binding linkage. The windshield wiper motor will continue to operate in a high/low speed condition for a period of 60 seconds.

Inspection and Verification

Verify the customer concern by operating the system.
Visually inspect the following for obvious signs of mechanical or electrical damage.

Visual Inspection Chart Mechanical Electrical
Windshield washer hoses
Wiper linkage
Multifunction switch

Thanks, I'm pretty sure it's the LCM now cause the wiper motor was replace, the MF switch was replaced and it still does it.

[captain]

Might want to verify adjustment first. Its cheaper.
