First step is get schematics for the wiper assembly (from a real FSM -
not from an aftermarket manual - you can buy an FSM, get the dealer to
photocopy the appropriate page(s) after you look at theirs and pick out
the pertinent page (s), or get an on line alldata.com subscription for
your vehicle - on-line availability if all schematics specific to your
vehicle right out of the FSM come with the subscription). Second step
is, from the schematics, logically determining what could fail that
would cause the symtoms. Third step would be to narrow it down and
pinpoint the cause with a multimeter and good troubleshooting skills.

Obviously the motor itself is OK, and the path that provides voltage to
the motor from pressing the washer button is good, but the main path for
normal wiper running has a problem.

Sounds like a deal. I have the FSM and can check it. I just thot if it
was a common problem, as it seems to be, someone might have a quick fix.


Thanx.

I have the same problem I think. I only got part of this thread.

The wipers on my 96 T&C are very picky about when they will work. The
washer does make them activate. They work some times. I changed out
the whole turn signal arm assembly and it seemed to work for a short
time, but I think it was just a fluke.

Have you found out what this may be?

checking the wipers to see if they work on spray is a step in troubleshooting
the wipers when they are inop. it's in the service manual
there is a tsb for testing the system since there has been so big time issues
with the wiper system so i would first check for fault codes in the bcm then
go from there so parts are not thrown at it.
