Check the wiper motor relay.  If that is good, put the old MFC switch in and see if the wipers work.  If they do then you have a bad MFC switch.  If they don't, then a bad wiper motor.

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.

I have a 1992 ford taurus changed the multi function switch changed windshield wiper motor checked the fuses and wipers still not working is a v6 3.0


Wire connection are the only thing left to check. But then again multi function may not be operational you just a have to ck connections motor for wiper may be bad also

Wipers do not work properly in delay mode


I hate to sound dumb, but have you replaced the multi function switch also? Do your wipers only work when you press the wash button?The Multi function switch is the actual wiper/bright control/turn signal switch. They go bad often in these models, I have a 96 town and country (108,000 miles and still love it) and have had the same problem.I have also heard of taking the wiper motor apart and cleaning the contacts (which I did, to no avail). I first started with the multi function switch, went on to the wiper motor and I cleaned (scraped) every electrical contact that has to do with the wiper, I pulled the BCM and checked for any cold solder joints, and I am currently waiting for my ordered new BCM and I hope that is the problem.
