A question on defroster vent behavior: is it possible to enable the defroster vent for fresh air without also enabling the A/C compressor? I often like fresh outside air in the cabin at ambient temperature with no heating or cooling applied. I can accomplish this in the HVAC control panel by tuning the A/C Off, Enabling Non-re-circulation, and selecting Dash and/or Floor vents. I then set the Temp = Lo on the "main" lower panel. However, as soon as I select the Windshield vent, it appears the A/C compressor kicks in, as the temp starts dropping. There is a separate set of front & rear defroster buttons on the main lower panel. I was hoping that as long as this front-defroster button remained disabled, I could keep the compressor from kicking in. Instead it just appears that enabling this main button is just a "shortcut" that quickly selects a preset that selects the windshield vents, cranks up the blower, etc... Has anybody discovered a way of doing what this? Thanks.
