No heat blowing.

Perfect timing by my car to start doing this. What is the remedy for this? I was thinking heater core but I'm not sure about it.

is the fan blowing? Check the plug behind the glovebox.

More than likely its your blend door actuator. You have to take the dash apart to get to it. Not an easy job but if you can turn a wrench you can have it done in less then 4 hours.

A temp fix vvvvv
