07 Grand Prix Heater works perfect one day then doesn't at all the next?

What is your question?

No smell inside the car of coolent, no leaks iv noticed, the coolent was just replaced and is full, I just would like to know what that is most likely a sign of.

How long has your 2007 Pontiac Grand Prix had this problem?

It just happens last week so 1 time it stoped working for 2 days and now it’s back to normal
