Re: 55 clipper wiper with washer and coordinator

Thanks to all for the info. Yes I have seen the Wiperman Ficken on the net. As an old ASE master tech I prefer to know the operation of each system then make repairs or decide on replacement or service. It is very interesting that the wiper systems can and have been fairly intricate systems through the years. My questions were:Are the Packard wipers supposed to "park" at bottom of the windshield no matter when in the cycle the switch is turned to the off pos. How does the coordinator affect the washer operation and though I am aware of the operation of the aux vacuum pump, I need more info on the check valve behind the carb and the " balancing valve" on the fire wall( see fig 13 pg 6 accessories sec of svc man.) Is this just a tee? I was able to get some info from the pattent description i found on .gov if anyone is interested I can maybe post a link to it as I am not sure I can repost the text without lic. seems the coordinator is a silicone gel filled dashpot solenoid supposed to continue to apply vacuum to operate the wiper motor for a "timed" 3 0r 4 swipes after the washer is engaged and is adj thru a screw and orafice to slow the silicone movement there by slowing the solenoids return. I have experienc with wax filled dashpots to slow choke movement on 80s carbs used by some japanese cars. I did notice a "one way" valve inside the Packard wiper motor which the working wiper motor does not have. Any thoughts?
