Even when engine is warmed up to running temp, only cold air comes out of vents when heater is on.

Are both the hoses hot. Are they both hot if so check the blend door. If not if one or neither is blled the system of air and do a radiator/heater core flush.

My heater was working fine. Then one day it would only work on high and nothing else. Now it doesn't blow air out at all. But if I put it on defrost it will defrost the window with no noise and you can't feel the heat. What could this be?

Sounds like your switch is going bad,
test for voltage at blower motor connector
with switch in various places, if theres
voltage it may be time for a new blower motor.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
