I need some help diagnosing a strange thing my car did today.
It's a cold day (7 degrees) and I was running errands. After my last stop the engine temp was reading right in the middle of the guage, but the air was still blowing cold. (Last winter, by the time the air started blowing on high, it was always blowing hot.) This has been happening a lot over the last couple of weeks.
About thirty seconds after the air started blowing on high, something in the car suddenly smelled like it was burning, and then the air blowing from the vents immediately went from cold to hot. The burning smell then went away.
Does anyone have any suggestions for what this may be? My best guess is that my thermostat is sticking and needs to be replaced.
