Impossible/w motor
Hey u all,got a 76 SR tTop,replaced the w/w motor 3 times and the switch 2 times,,ran new w / washer elect lines and new ground lines. Checking fuses ect all seem correct as per schematic. Wipers rotate 1 time and park. Adjusted internal wiper rods ,no binding. I know this is also a positive ground. The motor as it is always hot the grounding by switchputs it in selected speed. any suggestions ? Thanks

not positive ground. active low. pos is still pos but switching is done by grounding thru a switch. usually i won't correct somebody's terminology, but if you get literal with this you could be arc welding with your battery.

Make sure your ground wire goes to engine ground and not positive starter. The switches you buy are garbage! You can take apart and make sure they are working properly. I think the wiper motor is fine but try another switch or wiggle it a bit to see
