W126 AC wheezing
Strange I know but today with the ac set to 20c I turned the stereo all the way down and could hear the ac wheezing. Almost sounded like someone breathing in and out. Also the sound seemed to get louder as I accelerated. There didn't appear to be any pattern to the timing of the sound. I have had the car in for an ac inspection about a week earlier and they said everything was fine and just blew threw an anti bacterial spray. Appreciate anyones thoughts on this, this is definitely a new sound that has developed over the last few days.
