Blower motor

[Otwobme]

Do you have any air flow? If yes it could be a stuck open thermostat

is your carpet wet and smells like coolant? If yes your heater core is the issue

can you switch back and forth to cool and hot? if no than it could be your blend doors.

if no air flow it could be your blower switch.

check your relay as well.
