I have a 1995 Maxima with Automatic Climate Control. I recently had a new AC compressor installed. I just noticed that when I turn on my AC, that my radiator fans come on immediately and stay on (even when the engine has been sitting in a garage overnight and is cold). I recall in the past that my radiator fan came on only when the temperature reached a certain point (regardless of whether the AC was on or not). By the way, when I don’t turn on the AC, my radiator fans work fine – they come on only when the engine gets hot. But again, turning on the climate control automatically turns on (and keeps on) the radiator fans. I see this as an unnecessary electrical current drain when driving at highway speeds with the AC on. Also, I’m guessing that in the winter when I turn my defroster on, the radiator fans will also unnecessarily come on (since the defroster turns on the AC compressor). Any thoughts or suggestions are appreciated.

My fans turn on when I turn my AC on as well.

It's normal.

The a/c won't be cold without air flowing through the condenser to pull the heat out. That's why the fan turns on with the a/c on.

As stated, this is completely normal.
