White smoke coming from air conditoner vent. When a/c turned off, smoke stops. Normal engine temperature. No electrical smell. Nothing apparent under hood that I can detect.

This is normally fog, have the A/C drain tube check for blockage, there is excessive moisture in the A/C as a precaution get a cooling system pressure test done just to prove there is not a problem in the heater core as well.
