so ive replaced my switch and motor for my windshield wipers. theyre both good working parts so i know that isnt the problem. the harness is tucked so rubbing isnt an issue either. ive tested for power but it doesnt seem to be getting any. i havent pulled the dash out yet to look at it thoroughly though. basically what happened was that they worked fine for a while then one day i went to turn them on and nothing happened. now occasionally whenever i turn the car on they move for about a second give or take some fractions. would it be a bad ground? bunk wiring or what? i need to get this fixed because driving in the rain is becoming more and more frightening lol
