My blower motor comes on only when my selector (Defrost/Mix/Floor/Vent/etc.) is in the position shown in the picture. Anywhere else and the fan stops. So I suspect that selector would turn off the fan if the selector was all the way down in the Off position. So some switching of some sort is taking place through the selector somehow. Anybody have any ideas? Fixable?
