Well it is dumping rain at my house and i had to go to an appointment. I drove the truck and i could barely see. My wipers seem to be going slower than they should be and things when i have them turned all the way up sometimes they go real fast and other times it will just be a slow wiping. If i turn them off sometimes they just keep on wiping and you have to flip them on and off a few times till they quit. Does anyone know what may be causing them to not respond to the switch or wipe as fast as the should?
