My Impala's heater does not start blowing hot air when the car is turned on,
instead it blows hot air only after it has run a mile. Please suggest what needs
to be done.

Sounds normal too me, usually it more than a mile to warm up enough to start blowing warm air out of the heater. They are not electric, they are warmed up by the coolant heated by the engine and then it flows into the heater core to provide heat inside the car. HTH

That's pretty good heating I think. At -5F here in Montana, I'm happy if the heater works in 3 or 4 miles.
