I just picked up my new to me 355 today. This is the worst possible day - it is rainy and cold. On the drive home the window was super foggy and I had to keep wiping it. I also turned it to full heat but it kept blowing cold air even after the car was fully warmed up. My past Maserati had a pretty weak cooling system on hot days, but the heat at least worked. Is there something I can check? Or should I stop by the dealer tomorrow?
