So I replaced the fuse but no change. they do change from low to high speed but not intermittent or off! I leave the fuse out until I need to use them. I played with the arms to make sure there was nothing obstructing their end point for triggering the OFF switch ( wherever it is located, lol ).
Anyone know what could be the cause?

also if it is the motor, where can I find a replacement? Is it the same as a windshield wiper PUMP?
Or a relay replacement?

Thanks to anyone who can help!
