my a/c did this couple of times too. it works fine espeacially after recharge but sometimes it would blow warm and i have to restart the car and it would blow cold again. i were suspecting climate control unit since i replaced buttons on it and it didnt come out well because i had to incorporate w126 buttons in it but anyway i see that you have same problem so it might be something else. does anybody else have same problems? and anyone fixed it?
