My 96 GV had the phantom wiper problem, but that was cured several years
ago with a switch replacement. Now it has developed a new problem, also
intermittent like the phantom wipe problem. Occasionally the delay and
park functios of the wipers fail together. The wipers will only run
continuously no matter whether the switch is in the intermittent range
or full on. And when you turn them off, they stop ... right where they
are at. Then a few minutes later all is fine again.

I haven't yet dug into the schematics to see if there is a separate
control for the wipers or if this is another feature integrated into the
BCM. My BCM already has one failed component (the rear wiper switch)
and maybe this is yet another part going down the tubes. Anyone seen
this problem and know the solution?

Hi Matt,

I believe your problem is the "park switch," which is integral to the wiper
motor. The fix is to replace the wiper motor.

cheers!

Wonderful. Probably better than having to replace the BCM though. That
is $360 or thereabouts.


Thanks,
Matt

The LH cars have the same problem (I assume same design) - pretty much
exclusively in cold weather. How they have gotten by without an NHTSA
recall on this I'll never know since in the automotive design and legal
world, the wipers are considered no less of a safety system than the
brakes.

first codes have to be retrieved from the bcm.this will help properly
troubleshoot the issue ,possibly saving some cash buy not throwing parts at
it
if there is one for park switch failure, a new wiper motor is in order
could be there might be one code for the rear too
 
I had the exact same problem, and your symptoms are described exactly in the
manual as the wiper motor internal park switch failure. It is possible to
remove the motor, open the cover and clean the switch to make it work again.
When I did this, it would work again for a year or so, then fail again.
Since it is not such a simple re&re job, on the third year I broke down and
put in a new motor. Also due to the fact that you are right, the failure
usually occures when the weather gets very cold - not the best time to be
working in the cold.
 
could be the park switch in the wiper motor and or the BCM

Look for a bad ground at the stud located at the base of the transmission
dip stick.

I checked the service manual the the symptoms point to the wiper motor
unit, more specifically the park switch is bad as Glenn suggested.
Doesn't look like this one would likely be a bad ground.
