I have two new control valves for my rebuilt air wipers. I have three connection options on each valve. IN, OUT and PARK. Now, I get the first two and how they should be connected. Any idea of what the park function does and what it should be connected to? Also, on the wiper motors, I have IN, EXAUST and each end has PK listed on the ends. I cannot find a detailed diagram nor any mention of their hook up in the manuals.
Any ideas for tomorrow would be great!
Thanks

If you are talking about the dash control valve and not the valve mounted on the motor. "In" is your air supply, "Out" goes to the "In" port on the valve mounted on the motor, and "Park" goes to one of the "PK" ports on the motor's valve. I do not know why there are two "PK" ports, maybe so you can choose which side of the windshield you want the wiper to park at. Anyway, I had a lot of trouble with mine which were plumbed differently, but they seem to be working now.
