Almost all modern day automotive climate control systems will automatically switch into "comfort mode" (should be referred to as "less discomfort mode" IMMHO). Once your cabin temperature setpoint is reached, or closely nearby, these new system will switch airflow routing to the dash, face and upper body, and provide somewhat coolish/DRY (A/C dehumification) airflow, only warm enough to "just" sustain the cabin at/near your temperature setpoint.
Manually turning off the A/C during the non-cooling months will always help. With some systems you may have to disconnect the electrical connection to the A/C compressor clutch to accomplish an A/C function shutoff.

Some previous owner may have installed an Airsept(.com) EED, Ford dealers were for a time, maybe still, doing this if the owner complained LOUD enough about A/C odors or/and instances of inadvertent sudden windshield fogging.

"..air conditioning isn't used.."
Unless you find a way to disable it then it will run 24/7 unless the OAT is near or below 32F.

So the heater and A/C in my truck only works on full blast? anyone have a solution or know what I would need to fix it? Don't want to take it in and pay a ton to get it fixed but also don't want to die of heat this winter.... Seems to be a common issue with the trucks.....
