When I shut the wipers off, the go down, but won`t park. Instead they jump up & down a couple inches until the fuse is pulled.
It was decided in the electrical forum that the wiper arm adjustment may be the cause, not allowing the motor to come to "park". Some members loosened theirs and say this worked.
My question is, on the 69 GP, does anybody know how, or where, to adjust these?
Thanks!

My 72 Gp has the same problem. Often, but not always, when I attempt to shut off the wipers the just spaz out at the bottom of the windshield until I shut off the ignition switch at just the right moment (on their way down to the "park" position). Sometimes when I want to use the wipers they just spaz out instead of running. The problem showed up when I replaced the dash in my GP using all of the original wiring and switches. How do I fix this?
