Just got back from travel. I had a chance to pull out the wiper linkage and lube/clean everything. Yes the pivot on the passenger was rusted almost stuck.(Maintenance tip, lube your wipers at least once a year!) I was able to free everything up. Got my new motor in, but I am trying to figure out how to resync the blade position to the stopping position of the motor. I marked the back of the motor mounting bracket when I pulled the linkage apart, but it appears that the mark was off because the original motor was not in the right position when I pulled the lnkage. So how do you determine what position to mount the linkage to the wiper motor?
