There are 4 pins on my maruti wiper motor. how do i run it using a 12v battery?(connections?)

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 relay

High 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.

u need to order these items at any authorized maruti service centre.,as spares wont be availble in after market

when it happens you can use a hammer and tap the motor, if it starts the motor is worn and needs to be changed. also check the ground for the wiper motor. when it happens again connect a ground wire from the motor body to a good ground if it starts permanently connect the wire. these are the 2 most common problems that can occour.

Check the relays. The check for 12V at the wiper connector. Also check for a good ground between the wiper body and any metal surface. If they check out OK, but unit still wont run. Identify the 12V input to the motor. Connect it directly to the battery positive post. Unit runs problem is with the BCM. Unit does not run unit is bad or internal electronic controls is bad. Chrysler loves to run everything through the BCM (totally unnecessary) but it makes them a pile of money since many small things lights, etc run through the BCM and when they go bad the BCM needs replacing at $600 a crack! Nice scam huh?

the motor in all wipers motors boxes.
has a switch inside, called the keep alive or auto cancel;.
its bad.
ive fixed many a switch inside, most shops throw the whole thing way.
for good reason, they dont want you back next week for same problem.
on old cars we try to fix things. direct.

to prove this. we use a voltmeter
at the 2 power pins, one goes to 0volts when you turn it off
the other stays hot. 12v. this is normal
if the motor fails to stop, the motor internal switch is bad.

the tests are here.
http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service

under wipers chapter and wiring 8w-53-4
as you can see the rear motor has 3 wires.
pin 2 is ground
pin1 is keep alive pin, 12v.
pin 3 is demand, 12v wiper on, 0v wiper off.

if you cut the pin 3 wire, and the motor keeps going, the motor internal switch is bad.
if cutting pin 3 , kills the motor ,that means the hand switch is bad.
or shorted some way.

both blades fail to park.?
are the arms installed correctly?
so the wipers run , when you key on. ? is that it
tell me when exactly they move, and you didnt commend it.
here is how i do this, i log in to alldata.com
and see its a complex set of 5 parts, in the wiper schematic
2 relays (on/off and hi./low) and the wiper motor and the switch
and the controller.
so i take my handy voltmeter ($10 at walfart) and measure
pin 30 of the wiper relay on/off.
if it reads 12vdc (keyon, or off, with wipers off) this is a bad reading
if it reads 0v, , its good. easy huh
but what if the relay 30 pin read 12v
what would i do, id see if its being told to turn on.
id pull it out, is the wiper dead now. (yes, might be bad relay)
but id check the voltage across the 85/86 relay coil pins
12v is bad, the IPM is commanding wipers full time. (keyon)
0v is good, and relay is TOAST>

The IPM is the thing that holds the wiper switch.
it too can fail but i bet not.

How much current is the motor drawing? Most wiper motors draw between 8 and 10 Amps when they are working properly. If it is drawing considerably less, then the brushes are worn out. If it is drawing considerably more, the armature is shorting.

Testing the motor with it removed does not check to see if it can carry a load. The same tests should be done with the motor installed and carrying it's normal load (including friction resistance from the wiper blade). I have a feeling you will see a HUGE voltage drop between your 1st and 3rd pins if it is tested this way. If so, replace the motor.

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 senses magnet to turn off RUN/PARK sense the 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.

• The intermittent windshield wiper speed does not operate correctly

• Multifunction switch.
• Circuitry.
• Windshield wiper motor.

• Go To Pinpoint Test D .

Pinpoint Test D: The Intermittent Windshield Wiper Speed Does Not Operate Correctly
Normal Operation During normal operation, the windshield wiper motor receives voltage at all times through battery junction box (BJB) fuse 1 (30A), circuit 65 (DG). The windshield wiper motor also receives power with the ignition switch in RUN or ACC positions through central junction box (CJB) fuse 33 (15A), circuit 1002 (BK/PK). Ground is provided to the windshield wiper motor through circuit 676 (PK/OG) and circuit 57 (BK). The run/park and high/low relays are contained in the wiper motor electronics. Mode of operation is dependant on the signal(s) received from the multifunction switch.

why do you think the motor still works if the wipers don't move? Can you hear the motor run or can you see a little movement when you turn the switch on?

What happens when you activate the washers?

go to a salvage yard that allows you to remove the parts yourself. Then you can see how the motor and linkage assembly comes out.
