fuse ? Motor ? Check all fuses and if the fuse is good it could be the motor , It is not hard to replace .Pull the wiper arms and the three bolts that hold the motor in drop it out and replace it , put the wiper arms back on and try it >All of the bolts that hold it are under the hood .
tRY REMOVING THE WIPERS WHEN IN UP POSTION AND REINSTALLIMG THEM IN THE DOWN POSTION THEN TURN THE WIPERS ON AND SAEE WHAT HAPPENS THEN . ALSO CHECK ALL MOUNTS ON THE WIPER MOTOR AND ANY ADJUSTMENT LINKAGE TO SEE IF THEY ARE LOOSE AND MOVED IN ANY WAY
the wipers till work but they will not park in the down position, correct?
The usual fix for this is to replace the wiper motor pulse board. You can find them at your local auto parts store for about $50
the wiper motor will be under the plastic cowl that is under the wipers
arms. Once the wiper arms and cowl are removed you will see the wiper
I can give you some more details if you would
like to try to tackle this yourself. The wiper arms can sometimes be a
challenge to remove and often require a small two jaw pulley to press
them off from the posts. If you can get the wiper arms off the rest is a
breeze as long as you have some basic tools and a set of torx bits.
This is probably due to an electrical metal contact within the motor having broken. The contact is pushed by a cam to complete the wipers electrical cycle and stops when the wipers reach their park point on the screen.
The arms are released by holding the wiper blade fully extended away from the winshield and wiggle the arms off.
The blades are removed by a little tab where the blade hooks to the arm,using a small screwdriver push down on tab,and slide blade off arm but do not let arm slap windshield as it could crack it,I have seen people pull and the blades suddenly come off and the arm slaps down,yor can put a towel or cloth down where the arm sits against the windshield to prevent the possibilty of the arm slapping down.
I found the following description on the web, this covers a bunch of the questions I was going to ask...
I own a 2000 Silo and wondered the same thing and do see some GM vans with this problem.
When I bought mine I also bought the Haynes Repair manual (1997
thru 2001 all models GM) #38036 to learn how to fix this and a LOT of
other components in/on the van.
For $20 it's worth it.
To answer your question: If the wipers stop at the position
they're in when the switch is turned off (Fail to park), disconnect the
multi-function switch electrical connector. (This is located under the
dash next to the firewall and steering column)
If the wipers now park, replace the multi-function switch. If the
wipers still do NOT park, check the wiring from the wiper motor to the
switch for a short circuit. If the circuits are good, replace the wiper
Note: There are other adjustments needed for proper operation than just bolting and new motor on.
You can have a look at this manual at any automotive parts supply store.
