93 GC wipers do not park anymore
 

To all,

My 93 GC wipers do not park anymore. The wipers run normally at low
and high speed but if they are switched off they just stop where ever
they were on the windshield. This started when a bunch of snow slid
off the roof when driving and (apparently) overload the wipers (they
were on delay when this happened).

With older cars/trucks there was usually a parking electrical contact
inside the wiper motor however looking at the schematics it looks like
the wiper control module may control the wiper parking now with just a
feedback from a switch inside the motor.

Does anyone have any hints? Is there still a parking contact inside
the motor that may have been burned that I could try to fix or did the
wiper module get damaged internally?

I don't see any reason why they would change that design.

The wiper motor is a b*tch to repair. And if it's what I suspect
(broken parking gear/pawl) then your gonna have to replace the unit.

To make sure you should check the park system manually.
You have the service manual?

With the unit stopped in park, check the DarkBlue to Black.
Should be a short (or close) Also check the DarkBlue to
LightGreen/redstripe that should be open unless the unit
is parked.

the module could be fragged. But I don't have a schematic
for its guts.

Re: 93 GC wipers do not park anymore
 

I have a 1993 Grand also and had the same problem.

Don't touch the motor and dont worry about checking the schematics. Behind
the drivers side kick panel you will see a square module that is velcro'd to
the body. The module has two larger connections on it at both ends. This
module controls your wiper intermittant settings. You can replace the
module for about $35.00 from the stealership or you can do what I did since
I am a cheap bastard.. :)

There are 4 rivits holding the module together. I drilled out the rivets
and pryed open the module. Inside on the board you should see a blacked
area where a contact has been burned out. If you are handy with solder and
have a steady hand then you can repair the contact yourself. After that is
done I taped the panel back up with duck tape and stuck her back where she
came from. That was 4 weeks ago and I know have all my wiper settings back
and the wipers park afterwards.

I think what happens is exactly what you explained. The module tries to run
the wipers but burns out from pushing stuff that is to heavy.

Let me know if this works for you also. I got the information on this from
one of the many GC boards out there.

Cheers!
