My wipers have been fixed at the dealership 3 times now between 2002 and 2005. We leased this vehicle brand new.
To repair this problem you need to remove the cover over the wiper motor on the driver side of the car.
Remove the retaining nuts under the little caps that hold the arms on, put a pry bar under the bottom of the arm and hit the stud with a hammer lightly a few times. The arm should pop off.
Remove the hoses at the unions for the wiper fluid and set wipers aside (don't mix them up).
Remove the little plastic screws (they are two parts, take out the middle first with a screw driver, then pry up the bottom part, like you would a drywall anchor for a picture etc).
Pry up the little white plastic stud that holds the shroud on over the wiper motor. Set the shroud aside.
Remove the plastic cap from the wiper motor so you can see how it all works if you like or just do the following. You will see a bracket that has a little slot worn in it. When you cycle the wipers on intermitent, you will see a small tab or arm that if cycled the opposite way woudl catch on this worn brakcet. Simply take a hammer and screw driver and beat that bracket closer to the rotating assembly slightly until the little arm catches when you turn the wipers off. Fixed. Put the wipers back on in the rested position and tighten the nuts and put it all back together the way you took it apart.
After it's all back together, go back to the dealership and kick some butts. This is an altogether stupid problem caused by GM using a cheap cast bracket instead of a forged or punched bracket that would wear better. Worst of all, this happens on good not cheap cars like the Grand Prix and Intrigue all too often.
replace the wiper motor
There is a problem with the parking linkage. TAke it to a garage.
I've got a better question, why is this question in the Chevy venture forum ?
Refer to the link below. It'll take you to the answer elsewhere on this web site.
They could be stuck, possibly from snow, ice, or other types of precipitation.
You can detailed instructions on how to reset your wipers on youtube.com/watch?v=KFBLtlnkpuI
A bad pulse board or window wiper motor can cause your wipers to stay in the "up" position.
The car wipers should not stay up but return to their original position. The wipers will stay up if the wiper motor, the wiper controller and the wiper linkage are faulty.
replace the steering column.
There are two positions for the wipers on an ES330, winter and summer position. The summer position is down under the hood, and the winter position is where I imagine they are now. To switch between the two, just requires a push down to summer position, or a tug up to winter position. The idea between the two positions is that in winter, with snow on the car, the wipers won't get stuck underneath the hood, but during the summer, when that isn't a concern, they can be tucked out of the way for a cleaner look.
warm... NOT HOT. water pour it over and slowly peel the wipers up from one side to the other. then pull the wipers back( up?) so they are not in contact with windshield when not driving
why is it after I hooked up the linkage for my wipers the wipers stay in the upright position after I turn them off.
