Windshield Wiper Parking

[Jules]

Yes, this is helpful info. Being that I'd rather fix the motor than
replace it if possible I will probably go this route. First I plan on
checking to see if the motor to linkage has somehow slipped out of
place then if necessary I'll take apart the motor to see if I can
figure out what is going on.

Thank you for the info
