I have a 2005 300C, and I want to keep my A/C in the automatic mode, however I want to be able to block out the outside exhaust smells by switching (and keeping) the recirculation on. Apparently, the system only allows the recirculation to remain on for about 10 minutes then it turns off. Anyone know how to get around this time limit? I know I can leave recirculation on for as long as I want in the manual mode, but in the automatic mode it's a real pain to start smelling exhaust fumes, then having to turn recirculate back on.
