Hi gents.........I have an issue with my 2006 3i with manual a/c-heat controls. The air recirculate switch is always on (led is on)!....no matter what position i select for venting. It does send the air flow to the floor, vents and defrost fine and the recirculate/fresh air button does select between the two but its always lit up even if i have it on heat...AND the A/C compressor is cycling all the time!.....any ideas why this is not shutting off?...i was told it is not suppose to do this when on heat side and selected floor vents.....?
