This particular question is not meant for this newsgroup, but there appears
to be very knowledgeable people here, so I'll give it a shot.

When I stop my wipers they turn off half way across the window.
Do I just turn them off, remove wiper arms, and put them back on at bottom
of window and tighten nut. Or is it more to it than that?

its a chev venture van (ouch eh!)

Do they stop immediately when you turn them off or do they come to rest
at that position?

If you do that you might run into problams when it gets to it's outer
stop, probably not going far enough to clear the windshield.

I think you might have some electrical component failure somewhere; there
is a circuit that keeps the wiper active until it reaches the bottom
position. Either a broken wire or a failed capacitor or something similar.
I'm not familiar enough with (UGH!) Chevys to know how they work (sorry,
couldn't resist!

One thing you didn't mention: when you turn themoff, do they stop
IMMEDIATELY right where they were when you hit the switch, do they go a
little further after that like they're trying to reach the stop, and do
they ever return to the 'off' position?

This seems to be common, I see a lot of these vans driving with the wipers
not in the full off position.

Or, it could be merely friction; the wiper motor/regulator is gummed up
and there's friction stopping the wipers from reaching the stop position.

NO.
When I turn off the wipers if they are at the bottom (at the point of turn
off), then will then go to the top, then back down half way and stop.
So no matter when I turn them off, then will run its course untill it comes
back to resting position half way across the window.

If they did stop immediately when I shut them off, I would simply stop them
immediately as they reach the bottom of the window lol

Now you got more idea?
Do you still think removing wiper arms and re adjusting them won't work? I'm
thinking it won't as well........but worth a try.

I was hoping it was something simple. It doesn't look it.

Something is messed up (like, you didn't know that already...) but on
this model I don't know what it is.

Try to see if there is a repair manual online somewhere. It sounds like
some kind of timer or sensor, perhaps a feedback winding in the motor
that got screwed up. Did the kids grab the wipers and try to move them by
hand?

This is why I 'like' Chevys: nothing is ever simple...

no to the kids question
I don't think replacing the wiper motor would do the trick, bec. the wiper
motor is going strong............I'm at a loss!!!

The wiper motor has a gearbox attached. There is a switch on the gearbox
that is struck by a lobe on a gear. This gear has spun on its shaft and the
lobe is in the wrong place. You might be able to fix the gearbox, but I
doubt it. I think you need a new wiper motor. You could see if the parts
house will take the motor back if you don't open it. That way you could buy
the motor, and take the old motor apart to see if you can beat it into
submission, if not then you will have the new part to ready to put in.


I don't know where the wiper motor lives on that car, but odds favor it
living in a very inconvenient location.

The problem with the wipers is electrical, not mechanical. The problem is
not due to a spun lobe or improperly mounted arms, and removing the arms and
installing them in the lowest position runs the risk of damaging the motor
or transmission.

The wiper system has a park circuit, I don't know where it is in your van,
but it could be part of the motor, or switch. You will probably need an
electrical wiring diagram to diagnose the problem.

Do the wipers clean the proper arc across the windshield? Does it
stop at the bottom and side edges of the glass? Do the blades come
closer to hitting each other than on a sample car of the same make?
Is this car new to you?

DO NOT remove the arms from the 'axles' on the cowl until you see
how this works. All you will do is mess up the blade sweep arcs -
it's in the motor.

I'll bet the prior owner replaced the wiper motor with a junkyard
pull without understanding the subtleties - They use one basic motor
and gearbox (from Vario or Anco or Trico) so they can buy bulk and get
a deal. But they change the output crank arm and the mounting bracket
(and sometimes the stop position cam) to make that one motor fit 50
different car models and 200 body-style variations over a 20-year
span.

Somebody probably swapped in the junkyard wiper motor, but they also
used the crank arm that came with it - and it's meant for a different
car model. The new one has a "9-O-Clock" stopping position arm
(relative to a fixed reference like the motor armature) with a 2-1/2"
radius when your car needs a "12-O-Clock" stop position one with a
2-3/4" radius for a longer sweep arc.

You can see the position difference when you sit the crank arms side
by side - the wiper motor output shaft has a Single-D or Double-D
flats to position the arms in alignment with that stop switch on that
car model. The shorter the crank the shorter the sweep arc.
