did you check the heater core because my truck did that and that was what was wrong
Cold air blowing out of the heater is a sure sign of low coolant. Antifreeze running out of the front of the motor _could_ be a bad water pump. The two go together like ham & eggs.
find out what is wrong and then correct it. if you ask vague questions you are going to get vague answers.
The heater core is leaking. GEt a manual from DISCOUNTAUTOREPAIRMANUALS.COM and replace it.
Thermostat stuck open, clogged heater core, heater flow valve not functioning, or low of coolant.
most likely thermostat stuck less than $ 15 part
Have you checked the thermostat... Sound like a blocked radiator .................PS
Low coolant, stuck thermostat, blocked hoses.
I assume your car heater is blowing cold air, when the heater is on. It seems that, you have air on your coolant. that air pockets blocks the cooland to travel through your heater. it may be a sign of a bigger problem such as blown head gasket in the old cars, such acura legend
Is it water or coolant? If it's water, you probably have a leaky windshield seal. If it's coolant you could have a heater control valve leak.
I own a 1994 acura integra and the heater/air conditioning blower is not working, I can not defrost my windows and the heat does not blow. What is wrong and how can the problem be fixed.
if engine temperature ok, either air lock/blockage in heater exchange matrix or problem with heater control cable. in my case it was the headgasket on its way out. from dom coolent level stops it to if too low!
