Hey all, I've got a 2006 Prius package 4. A few weeks ago I noticed this really loud whine while the car was sitting idle in the garage (car powered on). I hadn't noticed this sound before and it definitely wasn't the usual whizzing and buzzing I'm used to. At first I thought it had been related to a charger that I had plugged into the power socket. I heard it again today and decided to pop the hood and take a look. Noticed it seemed to be coming from the front, on the left (standing in front of the car). I played around with the Climate control and noticed that the sound only comes on when the A/C is on. Turn off the A/C and keep the fan running, no noise. It seems too loud to be 'typical'. Has anyone had this issue? I did a search, but most of what I saw was on the 2004 models. BTW - the A/C seems to be working fine, frigid as usual.
The air conditioner compressor/motor does have kind of a whine to it; especially if it is running at high speed. It's not really noticeable unless you're outside the car. I've also noticed it when I've been driving in a parking garage with my windows down.
