Hi, I did check for the coolant reservoir and it's still up to Full level, I think it works in the morning when temperature is cold, but yesterday afternoon, outside temp was around 54 and I set for 72, I feel cool (not cold) coming out. How do I put it in Manual mode? I always have it at AUTO and 72 degree.

It's winter time and we have set Climate control to AUTO and 74 degree for both driver and passenger. Heat is not coming out but cold air. The car has less than 50,000 miles. Any idea of what it could be?
