AC was cold yesterday, hot today. I hear some hissing sound.
Like the title says, the AC was absolutely freezing the last time I drove the car, today it blows out warm air. I hear a hissing sound, seemingly from behind the dash, and only when the car is set to vent. If I set it to the floor or defoggers it doesn't hiss, but still blows out warm. The hiss also goes away if I hit the AC button. I figured by 2006, which is the year of my 300, that they'd be done with vacuum controlled AC switches, but am I mistaken? This is a 300 Touring, no dual climate control. Any ideas or do I gotta pull the dash and look for broken/disconnected vacuum lines? Can anybody link me some service manual pages?
