2001 dodge diesel 2500 wiper delay quit then blew fuse.tested amp draw too high changed wiper motor amps then only 2-5 amps schematic showed delay was in the switch assembly.I tested all wires for shorts,power and ground including wiggle tests. I was told that replacing the switch would fix the problem. Istill don't have delay, and still blows the fuse after short time period and restart.

I/P fuse panel - fuse #16 20 amp , really doubt fuse problem . More then likely the wiper control module or wiper motor it's self is the problem . An if the fuse is blown - short or high current draw blew it .

The motor could have a bad low winding. Intermittent always uses low.
The problem could also be a bad connector pin going to the motor low winding. If you have a schematic, you can ground the pin to see if low runs.
Hope this helps.

No there is not just one ,the rear has it's own fuse an relay . Fuse J - 20a in ( PDC ) power distribution center , relay should be in same box ! sorry don't have location number , can't find it !

Hi Maddie, I'm glad to help! Below, I have posted a diagnostic procedure to see why the wipers are not working on your Dakota. Hope this helps and have an awesome day Maddie!



DIAGNOSIS
WIPER MOTOR

The following are wiper motor system problems,
tests to be performed to locate the faulty part, and
the proper action to be taken. If the malfunction involves
only the delay mode, switch, or wiring, see the
diagnosis for Intermittent Wipe Module and Wiper/
Washer Switch.
CONDITION
Motor will not run in any wiper/washer
switch position.
PROCEDURE

(1) Check fuse 10 in the fuseblock module. If OK,
go to step 3. If not OK, replace fuse and go to next
step.
(2) Check motor operation in all wiper/washer
switch positions. If not OK and fuse blows, go to step
5. If not OK and fuse is OK, go to next step.
(3) Place wiper/washer switch in LOW position and
listen to motor. If you cannot hear it running, go to
next step. If motor is running, check motor output
shaft. If output shaft is not turning, replace motor
assembly. If it is turning, drive link to output shaft
or linkage is not properly connected. Replace worn
parts and/or properly connect drive link to the motor
output shaft.
(4) Connect a voltmeter between motor terminal L
and ground strap (Fig. 1). If there is little or no voltage
(less than 1 volt), move negative test lead from
the ground strap to battery negative terminal. If an
increase in voltage is noticed, the problem is a bad
ground circuit. Make sure the motor mounting is free
of paint and that mounting fasteners are tight. If
there is still no indication of voltage, the problem is
an open in wiring or faulty wiper/washer switch. If a
small increase (greater than 3 volts) in voltage is observed,
the problem is a faulty motor assembly.
(5) Disconnect motor wiring connector and replace
fuse. If fuse does not blow, motor is defective. If fuse
blows, wiper/washer switch or wiring is at fault.
CONDITION
Motor runs slowly at all speeds.
PROCEDURE

(1) Disconnect wiring harness connector at motor.
Remove wiper arms and blades. Connect an ammeter
between battery and terminal L on motor (Fig. 2). If
motor runs and average ammeter reading is more
than 6 amps, continue to next step. If motor runs
and average ammeter reading is less than 6 amps, go
to step 3.
(2) Check wiper linkage or pivots for binding or obstruction.
Disconnect drive link from motor. If motor
now runs and draws less than 3 amps, repair linkage
system. If motor continues to draw more than 3
amps, replace motor assembly.
(3) Check motor wiring harness for short between
high and low speed circuits. Connect a voltmeter or
test lamp to motor ground strap. Set wiper/washer
switch to LOW position. Connect other lead of voltmeter
(test lamp) to terminal H of the wiring harness.
If voltage is present, there is a short in the
wiring or wiper/washer switch. If no voltage is
present, go to next step.
(4) Set wiper/washer switch to HIGH position.
Move voltmeter (test lamp) lead from terminal H to
terminal L of the wiring harness. If voltage is
present, there is a short in the wiring or wiper/
washer switch.
CONDITION
Motor will run at high speed, but not at low
speed.

Motor will run at low speed, but not at high speed.

When they won't park it's 99% need new wiper motor

new motor is probably bad.maybe not grounded properly.you could also trya larger amp fuse.

If your wiper work on slow and high and delay does not work its wiper delay module need to be replace. Get one from a junk yard save you some cash, common on dodge vech. 04883827AA for windshield wiper motor delay module. hope that help some

It looks like the wire circuit for the wiper motor is touching the car body when shaken so the only thing you can do is shake the wires and terminals yourself while engine is running then maybe you can pinpoint where the earthing is.

If your voltage regulater in the charging system (distributor, altinater, battery, PCM) was replaced then the entire PCM where the volt. regulator nis held should have been replaced, so hopefully it was.
To check the charging system make sure when the truck is running the battery reads 13.5 to 14.5 volts (may go as high as 16) and when not running the battery should be at 12 volts. Any high and low voltages meen that the regulater or PCM are still bad and could be your problem.
to check the wiper circuit, pull its fuse and place a continuity tester over the fuse positions terminals, should have continuity, if not you have a wiring issue and the circuit needs tested at different sections until the break is found. Also the tester to check the wipers ground, place one test lead on a known/good grounding spot and the other on your wiper ground if there is no continuity than you are not grounded and you have to find the short.
You can get a Haynes repair manual that has all circuit diagrams in it, if your able to read circuit diagrams, hope this helps.
