Can Anyone explain why my Mystique would run cooler with the A/C going.

Without the A/C on the temp gauge points to the "M" in NORMAL.

With the A/C on, it points to the "O"... one would think it would run hotter. I'm confused confused !

With A/C on, Secondary cooling fans runs constantly, cooling the A/C condenser and the radiator. This tends to cool the radiaotr more than needed especially on cold days.
Without A/C on, the primary fan is temperature controlled so goes on and off based on temperature.
Most cars are like this.
