In most cases when a vehicle heater that has been working properly in the past begins to blow cold air the cooling system is low on coolant.
It could also mean that your heater core is clogged. A good coolant system flush might take care of this, otherwise you may have to have it replaced.

Jeep Cherokee heater does not blow hot air?
with any no heat complaint the first thing to check is going to be the coolant level. then make sure the vehicle is reaching proper operating temperature and that the thermostat is not stuck open or anything. from there check and see if both of the heater hoses are getting hot, those are the coolant hoses going into the firewall towards the passenger side of the vehicle. if one is hot and the other is cold that means you have a restricted heater core. you can try to backflush the heater core by taking a garden hose and connecting through the outlet side of the heater core and spraying out the inlet side. if that does not work you will have to replace the heater core. hope that helps.

Sticking thermostat could cause this. If the thermostat is stuck open, it never gives the engine a chance to fully heat the coolant. Follow the top radiator hose to the engine, remove the hose and remove what it hooks to and there's your thermostat.
