Close the fresh air. Do you have the heated windows? You might need an auxilary fan like often used in buses if you don't.

Run the A/C, it will dehumidify the air even with the heat turned up.

You should be fine.

No-your car does the same thing in Defrost.The air passes over the heater core and the evaporator core.The cool evaporator core removes the moist air which dehumidifies the cab,then is warmed by the heater core.Sometimes it's a balancing act between enough heat and defogging as the cool evaporator core reduces the heater output.The fogging is even worse with the blower!Good Luck!

Running the A/C will not hurt the HVAC system at all.

It is actually good practice to run the A/C in the winter/wet conditions to keep humidity down and it also helps to lubricate the seals in thenA/C system.

Good advice..... I also set the air to 'recirculate' and run the A/C with the heat on. :thumbsup:

Don't get in the cab with wet clothes.

Or work up a sweat by working outside in warm clothes and getting in a warm cab and being overdressed. I learned that cleaning out my barn.

I really don't mind snowblowing.
My B3030HSDC has it's own bay in the garage.I just warm it up then get in wearing shorts and slippers.
