When the a/c is on in my 2003 Legacy Wagon, a compressor kicks in every 30 seconds or so and runs for about 10-15 seconds. If my climate fan is on within the car, a loud whirring noise starts while this compressor is on and the noise builds with increasing engine revs (i.e., if I give the car gas). If I turn the climate fan off, no noise. If I turn the a/c off and just run the climate fan, I get only the normal climate fan noise.
This intermittent whirring when both a/c and the fan are on is driving me nuts - does anyone else have this??
