Blower motor increases speed by itself.
i noticed my blower motor increases speed by it self when NOT in auto, is this normal? It does not do it all the time seems to be when the air gets hotter.

When switching from fresh air mode to recirculation, the fan speed will increase because you are no longer pressurizing the cab. Just a thought .
