Thermostat and/or heater core may be defective
Can be a thermostat stuck open. Replace the thermostat and service the cooling system. Can also be a heater control valve malfunction.
this is not an answer just an update. coolant is filled
Could be a plugged heater core. Check the engine temp guage. if it is getting warm, your heater core could be plugged or restricted.
it is more than likely it is your heater blend door, it opens up to allow warm air to circulate. It cost me 350 to have the dealer fix it.
if the heater does not blow out warm air change the setting.
one because it is set on air only .. u need to shift it to warm first the RED mark...Secondly your heater wire must have come loose in the electricals. you should check out blendor store.com we had the same problem with our jeep, very helpful.
Engine will overheat or not get warm enough. As in the heater will only put out warm air. When you suspect that the thermostat may be defective, just replace it. Very inexpensive part.Engine will overheat or not get warm enough. As in the heater will only put out warm air. When you suspect that the thermostat may be defective, just replace it.

Isn't a heater supposed to blow warm air?
How long it takes a car heater to warm up depends on the temperature outside. In cold weather the heater can take several minutes to warm up.
