Default Electrical troubleshooting wipers on 86 Ramcharger


My wipers stopped the other day. I started at the switch and worked my
way up to the motor, I am pretty sure the problem is in the motor
itself, but it might be the intermittent control module. I don't know
how to test that, though, and hoping one of you might have some
insight.

This is why I think the switch is OK:
- The switch still works for the washer pump (press down on this
switch from any position).
- When moving the switch into any of the on positions, I can hear the
intermittent controller click.

I think the control arms and linkages are OK because the arms can't be
moved.

If the intermittent controller can be called good because it clicks
(can it? that's one question) then the problem is likely at the motor
or between the IC and the motor.

What I could use here are the electrical test procedures for the
intermittent controller and the wiper motor harness.

I'd love to get lucky and find out it's just brushes

Might be helpful if you included pertinent details on the truck you're
talking about...

what part of the header to his post did u miss.....................I cant
believe engine size matters to his question? I would think that his
questions would apply to anyone looking for the same problem, regardless of
engine size etc, cause that's all the extra info he posted. So does that
make this more relevant and you will now provide an answer to his question?
Somehow I doubt it

Fuse is good. Power is def being sent through the switch to the
intermittent controller, so I think the switch is ok too. The
intermittent is clicking when powered, so it MAY be good but I don't
have the test procedures to verify.

Geta friend and a meter, have the friend hit the switch, see if there is
anything going on between the controler and the motor with the meter.

break out your test light and connected it to ground then probe the "hot"
wire going to the motor. unplug it if you need to. with the light
connected between the power and ground when you cycle your wiper switch
you should see your test light "light up" should blink as the
intermittent wiper controller does its thing and should burn steady on
low/high.

consult your wiring diagram if in doubt what wires are the "hot" and
"ground"....best i can do for you as i dont have a wiring diagram or a 86
ram charger to look at.
