Question about Cars & Trucks
It depends on the problem. The system uses a programmer to control blend doors and the blower. The blend doors are controlled by vac and-or electric motors. When the temp flashes it is detecting a problem and may go into default mode.
You may need a scanner to access the body computer to diagnose it.
One of the blend doors is behind the glove box.

Ii had the same problem, fixed it temporarily by detaching the battery for a moment, this reset the blinking temp display. Nevertheless, the solution to the problem was filling the air condition up with coolant.

Check the temp of the heater hoses going into the heater from the engine in the engine compartment.
If you have a temp gauge on the dash does it go at least 1/3 the way up the gauge from cold in normal driving.
You can take a garden hose and flush the heater....both ways back and forth then reconnect heater hoses and check for heat.
But.....The # 1 cause of no or low heat is the engine thermostat.
It needs to close tightly to force the engine coolant through the small heater core.
