I think the switch could be bad. https://www.google.com/search?ie=UTF-8&client=ms-android- sprint-us&source=android- browser&q=1971+chevy+chevelle+wiper+switch#q=1971+chev y+chevelle+wiper+switch+dieigram

I agree. The wiper motor will have a constant ignition (switched) hot 12vdc. The switch on the dash breaks the ground to the motor on older gm vehicles. Chances are you have a bad switch allowing the ground path to make it back to the wiper motor, or the motor is picking up a ground from another source. Remove the switch and this should shut it down removing the ground path. Replace if this is the case.
