The steering wheel must be pulled to obtain access to the signal switch, but be careful if its equipped with an air bag there is what is known as a (clock spring) and it controls the puls used to activate the air bag.remove the battery negative cable before working on. its a circular yellow case just below the steering wheel. as you pull it off, be sure not to turn it either way.set it aside, and remove the hardware for the horn, and signal switch. replace switch and hardware, then look for an arrow marking, this is where the spring will need to point to during installation. after you replace all of this, replace the negative cable, but be careful not to be in front of the air bag, as if its wrong and you connect the cable to the battery then this will blow as soon as contact is made.

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.

Perhaps you need to start with fog light problem I am guessing we do not know for sure the switch was the cause, if you can remove them from the equation. When checking for shorts make sure you check light bulbs to,
Next, since the multi function switch was the next step in your problem solving, I suggest you remove the new switch check out all wires to the connector, be especially careful to make sure none of wires have pulled out or partially pulled out of the connector. Let me know when you finish this then we can move on to continuity testing.
My best guess is the connector as it is common to both your fog light and multi-function switch,
Above all don't let it get to you, these problems can be frustrating but they also can be interesting and fun especially with the right assistant

Hazards work but turn signals don't


I'd check your multi-function switch (on your steering column, what you touch to turn your turn signals on). There is a small metal clip on the base of it that tells your car to turn the turn signals on (right or left). Also trace the wires from the mulit-function switch to your turn signal relay and see if you're getting power when the switch is activated.

I have a 2004 Monte Carlo, my turn signals and flashers just stopped working, the fuse is good and all the bulbs are good. Does anyone have any other ideas as to what is causing this problem.


The turn signal switch assembly often causes this problem. If the hazard button is on your steering column it is part of the switch assembly and is called a multi-function switch . If it has a separate hazard button on the dash the can also cause the the same thing to happen. Try holding very slight pressure on the hazard button on the dash while the turn signal is on. If it starts working correctly replace only the the hazard switch. It is usually just snapped into the hole in the dash. If the hazard switch is on the column, than you should replace the multi-function switch. If it is equipped with an airbag, be sure the key is off while working on column. The multi-function switch should not require removal of the steering wheel on this car.

Low beams only work sometimes


Remove the plastic trim from around steering column so you can access the wires to the multi-function switch(turn signal switch).The RD/YE wire is the feed from the headlamp switch for low beams,it then leaves the multi-function switch on the RD/BK wire and feeds fuses no. 10 and 4 in the under dash fuse panel and from there to the headlamps right side is the DB/LG and left side is the WH/LG. Get you a 12V test light and make sure you have voltage in these places. I suspect that the multi-function switch itself has gone bad since you stated that they would work at times when you activated the turn signals.
