How do you replace the ''multi-function'' switch on 2nd gen Ram?

Intermittent wipers work sporadically. I have purchased a new switch, I need instructions on how to replace the bad one. I don't have a service manual...

Hi my name is Allen!

To replace the switch first remove the rubber handle for the tilt wheel by pulling it straight toward the steering wheel, because there is a torks head screw under it. Next remove the two torks head screws on the bottom of the cover. Next remove the rubber cover for the shifter and slide it out of the way. Next take the two screws out of the switch and remove it. I'm assuming you are talking about the swich on the steering column.

For further asistance you may reach me at FixYa!

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.

Wipers don't work in high speed and when intermittent wipers are set they stop in the middle of the windshield.


Yes that is likely a switch problem. Before you buy any parts have a shop confirm my guess.

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.

The wipers on my 2005 F-150XLT super cab 4X4 quit working. The washers come on briefly when I turn on the ignition. The washers stay on constantly if I turn the wiper switch to high. I need help! Thanks!


Hello, There is a good photo by photo description on F150 wiper switches at FordF150.net/How to/Fix-Intermittent-Wiper-Problem-PHP. It is the only solution I have seen on this problem.

Otherwise you need a new MFS-multi function- switch.

I hope you feel my solution is very helpful.

Wiper delay is not working already replace the multifuction sw assy


It may be a loose wire in the multi function switch connector that is connected to the multi function switch. The Haynes repair manual #30041 will show you step by step how to get to the switch.

Wipers won't stop wiping.


Sounds like your intermittent wiper circuit is defective. Normally the intermittent feature is engaged by one of the functions on the multi-function switch (usually on the steering column). The circuit of the intermittent wiper periodically activates a relay that closes across the "Wiper On" switch. Your intermittent wiper circuit is likely defective and holding its relay closed (or the relay is stuck closed), thereby keeping the wipers on. Note: The wiper motor has an internal switch that opens when the wipers are in the park position and that is designerd to stop the wipers in the park position. When you turn on the wipers (or the intermittent relay is closed), the motor's internal switch is shunted such that the wiper does not stop at the park point of the cycle.
