Hi all,

Today when the mustang was turned on the wipers came on by themselves and the windscreen sprayer was spraying water without the indicator lever being pressed in. After turning the car off and back on again a few times, that problem stopped. But now the windscreen sprayer won't work at all. I don't hear the pump when I press the multifunction switch. My best guess for this is that the multifunction switch is not working properly. I was going to try replacing it to see if it fixes...
