I think you have drawn a LOT of invalid conclusions here.

1)Anytime the AC is enabled, the compressor and the associated fans WILL run intermittently because part of the function is humidification.

2)A simple little fan will not draw enough power to have any measurable impact on your fuel mileage. (The compressor might.)

3) You might just be AWARE of what is happening.....that has been happening since day one. As things age, they tend to make more noise.

If this really bothers you so much, why don't you just turn the AC OFF ????
