Normally if the wiper arms park in the wrong place , it is the fitting of the wiper arms on the pivot that is wrong
try pulling the wipers back off the windscreen , run them through a cycle and then switch off normally
that will be the park position in the motor gear box
then remove each arm from the pivot and re- position it about 1" from the bottom of the screen
that will be the parked position for the wiper blades
having done that then again pull the arms back of the screen and cycle as if wiping the screen
switch of and see where the arms now park on the screen
if it is close to where you set them then that is the park position
next run the wipers a cycle and see if at full movement one arm puts the blade over the edge of the screen or hits the edge
switch off and re-position that arm closer to the bottom of the windscreen
it is time consuming but the only way to park wipers properly as there is no master spline to set in the correct position
If they park any where after this exercise ,replace the wiper unit as there is a problem in the contacts in the motor box.

i'm guessing that your question is more or less the same for your question about the wipers staying in the out wipe position when you turn them off?
i guess click HERE for the solution (although i'm sure you already know) :)

You will need to replace the wiper motor. Most likely the circuit board is bad. You might check with your local chevy dealer and see if there is a recall on the wiper motor before you buy a new one, even if you are not the original owner the car the recall will still be done free of charge. Some chevy models did have a wiper recall. I hope this helps.

sounds like wipers arm is not securely attached to shaft that is attached to wiper motors. They can strip out and you can either us JB weld to put them on or get new ones or junk yard ones.
SOURCE: wipers would not park, customer forced down wiper
Before 1995 Ford interval wiper systems mainly consisted of a switch, the motor and the interval governor (also called the wiper control module or 'WCM'). The basic wiper systems just parked the wipers at the end of their travel at the base of the windshield and involved just one park switch.
The more complex systems not only stopped the wipers at the base of the windshield, but would actually recess them below the windshield to park them. This involved using two park switches to turn the wiper motor in a reverse direction. These were installed on the Crown Victoria, Grand Marquis, Town Car, Taurus and Sable.
The wiper switch (named 'Multi-Function Switch' on most models) had a common return or ground circuit and two input or signal circuits to the WCM. Basically, the switch was two modified potentiometers that varied the resistance to ground for the two signal circuits. When the wiper switch was placed in the low or high position, the WCM looked at only one of the circuits- the 'mode input' -and controlled the wiper motor accordingly. If the wiper switch was placed in any of the interval positions, the mode input told the WCM that the switch was in an interval position. The WCM then looked at the second input - the 'delay input' - and used it to determine the amount of delay between wipes.
1) To run the wipers on low or high speed, the WCM provided constant power to the wiper motor on the proper circuit to provide the requested speed. Dual park switch motors
1.1 The first park switch operated basically in the same way as the single switch systems.
1.2 The second park switch worked in the opposite manner- when the wipers were off the park position, the second switch provided a ground for the wiper motor. Power and ground were now provided by the park switches.
1.3 When the wipers needed to park, the polarity of the switches changed, and thus provided reversed voltage to drive the motor in the opposite direction.
2) To run the interval wipers, the WCM applied voltage to the wiper motor only momentarily to get the wipers off the parked position.
3) The electro-mechanical park switch made a circuit between the power feed in and the output to the WCM. Power was provided from the park switch through the WCM and back to the wiper motor.
4) When the wipers reached the park position, the park switch made a circuit between the ground and the output to the WCM, and the motor stopped running. The wiper motor and the wiper switch have remained much the same as the single park switch motors of the past.
The main difference is that the switch has become an input to the GEM instead of the WCM.
1) When the wiper switch is placed in the low or high position, the Run-Park relay is grounded by the GEM to provide constant voltage to the High-Low relay, which then provides voltage to the proper circuit of the wiper motor.
2) High-Low relay is in the low speed position unless grounded by the GEM.
3) The park switch not only feeds the Run-Park relay but is now also an input to the GEM. This tells the GEM when the wipers are in the parked position so it can de-energize the Run-Park relay.
4) When any of the interval positions are selected, the Run-Park relay is momentarily grounded to get the wipers off the parked position
5) The park switch then provides voltage to the other set of contacts in the Run-Park relay.
6) When the GEM de-energizes the Run- Park relay, voltage is still provided from the park switch to the High-Low relay and the wipers complete the stroke.

SOURCE: wipers quit working low speed & delay, wont park. work fine high speed. have changed sw, didnt help
When they won't park it's 99% need new wiper motor
