Wipers operating weird
Hello All:
Relatively new here and looking for some help or suggestions please. I have a 1970 GMC with a new wiper motor in it. It worked fine last year when I installed it in Aug 2017. Now after bringing it out of storage and putting a new windshield and wipers on it the wipers don't sweep properly. When I turn on the switch (also New) the wipers first go down and overlap onto the windshield trim and down onto the cowl before making a full sweep over the windshield. When I turn off the wipers they park correctly in the correct location. I am at a loss as to where to begin checking this out. Any help is greatly appreciated.
Thanks in advance!
