I am trying to replace the front wiper motor for my 2001 chevy venture. The wipers are not parking fully down, and the intermittent setting parks the wipers about half way up until it is ready to wipe again. the reason i am replacing the motor in the first place is because when i shut the wipers off last weekend, they "parked" in the fully open position instead of below the windshield.

the linkage has disconnected somewhere. you need to remove the wiper arms and the panel(s) which cover the mechanism. the problem and the solution will be much clearer then.

you need to replace the wiper motor park switch.it is part of the cover board.

I would be looking at replacing the wiper motor....the wiper switch is just that, a switch to tell the wiper motor what to do.....most of the wiring is housed internal of the wiper motor such as the park circuit and the speeds........osunds like an internal fault.....replacement would be advised

Your windshield arm is in need of repositioning. Take off the cap on the windshield arm and loosen the nut under the cap. Reposition the arm so that it faces 180 degrees flat to the passenger side of the car. Tighten the nut. This should solve the problem you've described.

the park position is not working on ur circuit board,,need new wiper mot

This is a common problem with Chevy Venture, Olds Silhouette, and  Pontiac Montana. The mechanical wiper drive and parking cam assembly, if it's not broken, needs adjustment. The spring loaded stop arm should engage the vertical tab on the assembly mounting plate when the wiper motor reverses. See pic. 
I will upload the instructions to fix this problem, if there is interest.

disconnect the negative battery post.
disconnect the harness from the wipper motor, using a 8mm socket, loosen the two crank arm socket screws and lock-washers until the socket releasesfrom the crank arm ball. do not remove the crank arm from the motor.
using a 10mm socket, remove the three motor retaining screws, slide the motor out of the slot in the bracket.
To install make sure the wipers are in the park position, slide the motor into the slot in the bracket. using the 10mm socket, install the three motor retaining screws and tighten to 49-80inch lbs.Using the 8mm socket tighten the two crank arm socket srews and lock washers. connect the harness to the wiper motor.connect the negative battery cable

I found problem to be that corrosion sets in between the CAMS plates that circle in an opposing fashion and does not let the wiper arms park correctly. Be very careful with this mechanism if you have the cowling off TURN the KEY and WIPERS OFF and watch your fingers so you don't get them caught.
WARNING if you leave the power on and try to move the arms This cam mechanism springs to life and will try to self park the wipers on their own so Turn the Power and Wipers Off.
SOLUTION: 1. With the ENGINE COLD, Spray a lubricant that FREE'S CORRODED PARTS like WD-40 between the gap of the 2 CAM Plates and on Top of the plates, or use some other automotive parts lubricant that free's corroded parts(let it soak for 5 minutes). 2. Gently Try to manually move the arms back and forth a little bit so that the spray works into the parts. 3. This may not be necessary but I had to do this the first time. There is a notch in the top cam that has a STUD that locks the 2 CAMs together. You can push on this STUD to unlock the cams by manually moving the wipers(use a screw driver to push on the STUD and have a friend gently move the wipers manually. Spray the area LIBERALLY with with the Lubricant Spray and see if you can move the CAMS back and forth and work the lubricant in.
Then with the wiper cover out of the way and all tools clear Try to cycle the wipers HIGH and LOW, ON and OFF a few times it may stick the first couple times with the wipers in the up position but I am confident that the lubricant will work its way in and free these CAMS the way they are supposed to. Your wipers should self park after cycling them after 5-10times. This should solve most of the problems with these wipers and should be relubricated as needed. Clean up any extra lubricant Put the wiper cover back on.

disconnect the wiper transmission from the motor, then run the motor and turn the motor off with the wiper switch, this will park the motor, re-attach the wiper trans linkage so the wipers are parked/down
