one more thing, could the squeeking also be if your AC is going out?
since it feeds from the alternator belt, and I remember last year I watched some videos how to tell which pully is making the squeeking and I think when I tested with the screwdriver method that the AC pully was the one most likely doing it.
also my AC isn't always properly working on full blast, most of the time when you press the AC button the button turns green and all works well, but from time to time when you press the AC button the button doesn't turns green- but the AC still works-however with less power and less effective, would that indicate that there is fault with the AC since the button doesn't turns green when you press it and the AC isn't as effective as when the button turns green when pressed?
Quite expensive part if have to change it all
