WINDSHEILD WASHER PUMP

2003 GMC Envoy • 6 cylinder 2WD Automatic •

I have a 2003 GMC Enoy that will not pump washer fluid in the front since running the water out of the reservoir (replacing with windsheild fulid) in the fall. I have replaced the motor of the pump and replaced the fuse still with no fluid pumping and no noise of a running motor. The issues may be electrical. How do I test for power or any other ideas of cause?
