Hi. So the motor works fine. Also, the wipers go back to their resting position when I turn on the ignition (after I played around with the motor to get the wipers to stop in the middle of the windshield). Also, when I pull the wiper relay on the side of the bus and apply power to one of the contacts the wipers start working.
Oddly, there is no hot wire leading to the relay. It is my understanding that there should always be a hot wire which gets connected to another wire when the relay coil is activated.
Further surprising to me is that I don't hear a click on the relay (which I of course replaced) when the wipers get switched on. I am thinking that there may be 2 problems: the low amperage wire (from the switch) does not work to turn on the relay and the high amperage wire is not present. Any thoughts? thank you
