Heater problem

why does the heater not work, the AC is cold, the temp gauge shows 190degrees, but very little heat comes out, plus where is the radiator drain plug

Check the coolant level then turn around and replace the thermostat and see what happens-lets do this simple ones 1st-before I get technical.

If its hard to find just disconnnect the bottom hose to drain the Rad-
