My Windshield Wipers only work on a preset which is high, lately it's been raining alot and if i want to switch it to mist or lower speed it won't work, the only speed that it works it's high.
Any idea what the cause might be? Maybe the fuse or a faulty Switch, can anyone help me this thing it's been troubling me for days.

 

Change switch. See if that fixes it.
