I wrote to the board last week about a buzzing in the climate control that happens occasioally. I thought it was the fan and wrote the quesion as such. Turns out, the fan is fine, functions fine, and is not rubbing or making any noises, as I can turn the fan up or down independantly of the noise I hear. The noise that I am hearing sounds kind of like a stuck servo motor or something, thats the only way I can discribe it. Happens only occasionally and will stop within seconds if I turn the climate control OFF or turn the ECON button on. AC compressor perhaps? Its cold as **** here, but maybe its conditioning the air anyhow to remove extra moisture or something? Anyhow, it sounds like some kind of an acuator or servo of some kind, maybe the AC clutch. Any incite would be great. Thanks!

AC clutch I doubt because the noise is faint and can be heard in the cabin so ill go for relay noise or vent sensors

Thanks, though the noise is not faint, its pretty loud. Like about as loud as an electric drill, and more mechanical than electrical hum. Its so subjective saying "hum" or what ever, i guess its a loud humming/groaning noise about as loud as a drill.
