Hi All When I put the car heater on and don't use the fan, warmth comes through the vents when on the fresh air mode. However when I put on the fan the Air Conditioning (A/C) light comes on and I feel the loss of power that happens when I am using the A/C. It appears that when the fan is on, the A/C is also on and I therefore cannot opperate the car heater with the A/C automatically comming on. Does this sound right? Thanks David
