I need some ideas...

1) I keep running low on coolant. I haven't seen any smoke coming out of the exhaust.2) If I don't have the air running, it'll be about a week or two before my light comes on and I'm low on coolant. HOWEVER, if I do have my air running, the next day the light comes on and I'm low.

Any ideas? Heater core maybe? Blower? Water pump leak?

if you are runnign your air your engine will tend to run a bit hotter as the condensor heats the air before the radiator gets it, you migh have a pinhole leak at or near the radiator, try getting ahold of a cooling system rpessurizer that'll make finding any leaks a lot easier
