Wipers will not shut off

Hi,

Either the switch has failed or there is a short to power. My first suspect is the switch. However, I want you to try something. Remove the wiper fuse in the interior fuse box. See pic 1. See if they still turn on. If they do, then we have a short to power (a different power supply). If they don't, replace the switch.
