I have a problem with the windshield wiper pump,it doesn't hum or anything, it does nothing. front and rear. I pulled the battery to reset it and it worked for a min. then nothing again. it is not the fuse and the pump works when it gets power, it seems like it just doesn't get power for some reason. Is replacing the neg batt cable a thing? I have read that whatever fusable link is on the neg cable get corroded and goes bad, mine is clean but not perfect. Any suggestionns?
