SW2 windshield wipers are posessed

The wipers on my 96 SW2 with 60K are turning on all by themselves about once
a week. Playing with the wiper on/off and delay switch doesn't seem to have
any effect. Only way I have found to stop them so far is to shut the car
off when the wipers are down. Anybody have ideas on a cause and/or fix ?

 

Hey.... I am having the same problem with my 98 SW1. Exactly the same
problem.... If you find out what it is then please let me know. I will do
the same. Thanks, Mike Gaynor

Sounds like the park switch on the wiper motor acting up. When you turn off
the power to the wipers it keeps power to the wiper motor until they are
almost at the parked position and the motor should coast to a stop with the
wipers parked. The switch may not open soon enough, long enough or at all.
It may be a worn cam, loose switch or other problem with that part of the
wiper circuit. Opps - just looked at the schematic for the 95 S series. The
wiper motor is controlled by a module that is part of the motor that is
electronic. So it's just got more complex as the switch may not be
mechanical. It could be a magnetic reed switch, hall effect sensor or
something else. The problem may also be somthing electronic in the module. I
can't really tell you more without one to take apart.
If mine was acting up I'd have it apart tommorow and tell you what's up.

Mine was doing the same on my 96 SW2. The wiper module was bad, but
unfortunately, this is an integral part of the wiper motor assembly.
You have to replace thw whole shebang as a unit. It's a pretty involved
task, but if you're handy with tools and not breaking lots of funky
little plastic pieces, doable. The Chilton's manual gives OK instructions.
Make sure you disable the airbag before diving under the dash!

Mine is no longer posessed after replacing the wipre motor assembly.
Good luck!

Thanks for the insights and recommendations all. I'll be sure to pass along
whatever I find when I pull it apart.
