My fan heating and defrost not start when the car is cold at(-15 degree)and
under. Nothing open on the heater control unit no reading just light around
casting. After e time  engine adjust températur and it works. Where is the
problem.

Could this be an explanation for what you are observing?

Delay Mode
The delay mode is used to prevent the vehicle occupant's breath from fogging
the windshield when the outside temperature is low and the engine is cold.
The heater-A/C control will set the doors so that airflow is directed to the
windshield with low blower operation. The system will stay in the delay mode
until engine coolant temperature reaches 49°C (120°F) or after four minutes
whenever comes first. The heater-A/C control then operate normally in the
selected mode.

Even when the car is hot the heating does not function more, it there has
to you it a means of knowing or where is the origin of the problem, a
resistance a bad ground or a programation. The belt broken before and the
engine come hot just a moment, one week later the disorder appeared.
