What is this for....
On the A/C vent below the middle glove box are two buttons...one is red and the other blue...obviously..hot and cold....but what for? Turning on the A/C...system is cold without pressing the blue button...anyone care to explain what it's purpose is? Thank you!




my e320 has a blue roller knob which can be set to off which makes the center ones blow the same as the sides vs when i put it up all the way to max blue, it becomes very cold. this was removed for the E cars for 2005.
