I just bought my new 2015 WRX Premium about 2 weeks ago and I'm beginning to notice a bit of droning noise coming from underneath the glove box whenever the climate control is on. The noise persists regardless of any climate control settings I change. It sounds like a small electric motor or component operating underneath the glove box. It also has a bit of a fast-repeating click to it. It isn't terribly loud but it is somewhat annoying and doesn't seem like the system should be that audible when operating correctly.
The noise may have been going since I bought the car and I could have missed it since I've been so excited with everything else so it's hard to determine if something actually went wrong. Is this droning sound normal when the climate control is engaged on the 2015 WRX? If anyone else has noticed this and can confirm it to be normal it would be great to hear
