For the past month or so my AC hasn’t been working. The light blinks a couple times and then turns off. I have replaced the compressor which was in bad condition and it worked for about 10 seconds said my mechanic. And then it turned off and then kept blinking. I have seen that Mercedes has a AC reset function but I haven’t been able to get it to work on my car. I haven’t been able to locate it in the manual either. Is there even this reset function on a 2009 C300? Or am I just really stupid?
