so my 1995 850 187000 miles auto base model died as I was getting home yesterday then when I turned the key there was nothing about 2 minutes later it started , and it hasnt died since , starts right up , for the last few weeks there was a noise that is gone now like a loud buzzing behind the AC controls , when the car died there was a faint smell of something burning , I read this about the Ac evaporator making that kind of noise , but will it make the car die ad will it smell like burning?? any ideas and help much appreciated

thanks
