I have a 2005 Limited coupe and have had it for 6 years or so and 150,000 miles, drive it year round. I have been having some periodic issues with the blower motor just cutting out and not operating. There doesn't seem to be a consistent cause, timing, etc.. Now I am also getting a squeal from it at various speeds. Do I need to replace the blower and resistor or is there some other explanation? I am also experiencing issues with my seat heaters sometimes not operating, the lights on the switch don't stay lit and don't heat. Some days they work fine. Maybe it's just tired of this Wisconsin winter that doesn't seem to want to end.

Thanks in advance for your thoughts.
