About a week ago I noticed that my A/C seemed to come on after I'd parked and shut off engine. It stopped after a moment though,so thought maybe just a fluke. But, the other night it did it after my husband had driven it over an hour before and the fan was on then. Second time, the air blowing was not cold, just like recirculated. Now everytime I us the car, it stays on a good 2-5 minutes...

Other recent issue that may help in diagnosing- my Low Coolant light is flashing intermittently. Owners manual only indicates a steady light on as an issue to take action with radiator/antifeeze, no blinking. Hubby addressed coolant and possible issues with antifreeze to no avail.

Any idea? Wiring?

Thanks all!

some confusion on my part.... are you talking about the HVAC blower motor running, forcing air out of your dash vents?

or are you hearing the engine cooling fan running? if so your problems are more then likely related. you are probably loosing coolant making the engine run hott and after you shut the car down the electric fan is running to bring the temp down

Hmm? I think there's a blower relay that can stick and blower will continue with car off - keys out - that's the blower for inside cabin - right?

Low coolant light: Sensed on tank of radiator usually. This may not have a cap on the radiator to check fluid level actually in the radiator but a recovery tank that may be showing proper level and with certain problems it doesn't indicated the real level in the radiator/cooling system itself. If it's that type you might (engine cold and off) just squeeze the upper radiator hose and see bubbles at the recovery tank as a clue that rad is in fact getting low - the reason why is more important than just being low,

The air is coming on inside the car. When the air stops in side, there is no extra fan noise heard in the engine itself.

No indication on temp gauge that the car is hot or over heating... does that help?

Ok: That's the blower motor. There's a relay for it to check and or replace,
