I have a 2014 Berkshire and I'm planning to upgrade the buzzy windshield fans. They're set up as 2 speed fans controlled by a 3way rocker switch on the dash. Can someone tell me how those are wired for 2 speed? I'm assuming 2 different voltages from the dash switch. Is that correct, and does someone know what voltages? Looking at replacing the fans with something from the Hella Turbo series.
