I have the factory air wipers on a 77 mci-8 and while troubleshooting issues with them not working well ive come across a possible problem.

Will the air wipers not work if the port labled PK (to the right of the IN port) is not connected?

Also, since the air motors have 2 ports labled PK does it matter which one is used?

Those are your park ports. they control where your wipers stop. on mine and in my 5 book they have hoses on each IIRC. they open and close with air feeds to them from the controls.

   I just rebuilt mine on my 4905. It has both outlets, however one isn't drilled depending on which side of the coach the motor is mounted.

Well the only thing i did was put new compression nuts on the air line to the wiper motors and they work fine...must have been leaking air.

Thanks for the suggesions.
