C300 2023 model
I have a C300 2023 model — all is working great but since my last service last week the car has been blowing/venting warm air while parked. It used to be while off and parked there was a low ventilation happening but never blowing hot air. A quick google search is telling me that it might be a faulty ac unit at some level. Am wondering if anybody got the same problem before and could give me cues as to what might cause hot air to circulate when the car is off and parked. I’m gonna contact the dealership that did the servicing first thing tomorrow am but I thought I’d check here in the meantime. Thanks for any lead!
