My windshield wipers quit working even though a new wiper motor replaced the old on 1997 GMC 1500 Pickup

one only a year+ ago. I checked the fuses and they're all good. Can you help?

You need to follow test procedures for testing the wiper motor and wiper switch. Autozone have some popular workshop manuals for free on line once you register (for free) on their website There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate
Alldata is best.
