Air con noise
When switching on air con there is a noise coming from engine compartment. Its like a whirring sound, and changes with engine speed.
Air con is working fine, it is just noisy, is something on the way out do you think?? |

Noisy compressor.
Radiator fan MUST be running with AC on. (notorious) Adding PAG oil cures 50% of noisy compressors if cooling fan hasn't been duff for too long.
