what is the make and model and can you hear the blower motor running
When you have the heater on, does it just blow any air at all? or no air?
first of all i hate to say an obvious answer but does the heater motor even turn. Does it blow air at all. The first thing i would check is if the fan motor is blowing any air at all. If not u need to put in a new heater fan motor. first of all i hate to say an obvious answer but does the heater motor even turn. Does it blow air at all.

Because that's the way there made to blow hot airbecause it's not like a heater and it's not like something that makes it cold it blows any kind of air .
Your front blower motor has gone out. There is a front and a rear blower motor.
Any heater that only blows luke warm air isn't getting warm or hot water to the coil. This sounds like a problem with the thermostat not closing, and allowing the engine to heat the water properly for the heater.
your heater core hoses could be plugged up and not letting much hot anti-freeze into the heater core then when you try to blow alot of air through it it cools the warm air off too much and you get not so warm air. try a cooling sytem flush
that heppend to my car i had to finaly replace the heater blower so it could be the same thing
A vacuum leak, or one of the doors is sticking/bad vacuum motor in the heater box.
You need to first check that you do not have any vacuum leaks and then check the a/c / heater door operations, if all are working then its possible that you have a slightly clogged heater core.........
indoor air fan is not functioning. for that, there are many possibilities.
No. It can be a blown fuse, bad fan motor switch, bad fan motor, bad fan motor resistor pack, or a loose or disconnected wire.
Any of the following can cause this......... 1. Bad a/c - heater controller.. 2. Bad a/c - heater controller inside door operation.. 3. Bad, broken or cracked vacuum line/lines..
