Replace the heater core. It is leaking.
If water is only drawn from the cold faucet, then no, the water heater is not involved. However, if water is drawn from the hot faucet- even for a few seconds- hot water IS withdrawn from the heater, and fresh cold water drawn in to be heated- even if the hot water did not make it all the way through the pipe to the faucet- and the water heater will work to heat that fresh cold water.
heater switch needs replaced
Thermostat stuck open or heater core plugged. CONSIDER THE POSSIBILITY YOUR HEATER VALVE IS CLOSED/CABLE RENDERED INOPERATIVE BY A BROKEN PLASTIC SLIDER HOUSING,AS IS OFTEN THE CASE ON OTHER MODELS/MAKES,SHOULD IT NEVER WARM UP.
The first thing that you need to check will be to see if the controller in the dash is working the a/c and heater doors under the dash................
why is my 2006 Altima blowing cold air when not in motion , example stop light or as soon as it is idling even when it has ran for a long time and the engine is warm. The controls for the "doors"(vent covers that direct the air)are run by vacuum. There cold be a vacuum leak of one of the doors is stuck.
The blend door is probably stuck.
No. Even in a strong wind, 70 degrees would still feel warm.
Hot water is lighter then cold water so it would stay up on top of cold water till both waters naturalize to the same temp. a good example is a water heater and (if its not to old) open your drain at the bottom of the water heater and if your dip tube is still good you should always get cold water out of it even if the water heater is on and your water heater pressure is on.
first of all i hate to say an obvious answer but does the heater motor even turn. Does it blow air at all. The first thing i would check is if the fan motor is blowing any air at all. If not u need to put in a new heater fan motor. first of all i hate to say an obvious answer but does the heater motor even turn. Does it blow air at all.

Your heater core is leaking in it's housing box and blowing moist air through the heater/defroster. Try bardall radiator stop leak. If no help, install new heater core. Chuck.
the defroster is actually your a/c. it doesn't run much when it's cold outside but it works with your heater to remove the moisture from inside the car. blowing warm dry air on the windshield. just like it removes the moisture (humidity) from inside the car in the summer. the difference is the temp. you have it on. even if the a/c don't work, the heater will still do the job, just not quite as well.
I have a 2002 Jeep Grand Cherokee Laredo that was doing the same thing. The problem was a faulty ac/heater switch. You put the switch on ac, compresser engages, lines get cold and frosty, but only hot air is coming out of the vents, because the switch has changed back to heater even though it shows ac. The cure is to have the center panel which contains the ac/heater switch, fan speed switch and temperature control replaced.
Sell the car! Mang
Is is blowing hot air on the drivers side, or nothing at all? If it is blowing hot air even though you have the thermostat set on cold - it could be the heat actuator. It will occasionally do this after about 75000 miles or so. Mine started at 114000 miles and if you turn it off and turn it back on - it will start blowing cold again...$400 repair. Hope this helps.
Not necessarily. Your nose actually may even get a little more irritated, because of the constant contact of your nose, but it will get all of the snot out
I would say that your heater core is ok...it sounds like you have a bled door promlem in the dash.
Not really in any big way. Being out in cold weather does not cause the common cold. While a noticeable increase in the numbers of common colds and the flu season happen during the winter, it is the microorganisms that cause the common cold and flu and not the temperature. However, cold weather could make certain symptoms worse. For instance, a runny nose can be worse when out in the cold even if you don't have a common cold viral infection. Being out when you have a cold adds to the constant blowing and wiping of your nose. That can cause the skin to become raw and dry which allows the cold temperature to accentuate the soreness.
thermostate stuck open need new thermostate
Maybe you have a bad heater core and it's causing the ac to blow hot air in instead of blowing cold air inside your car that's what's wrong with my 91 Chevy Caprice and we put freon and checked it and it blows hot air like what you are saying i was told that it was something with the heater core so to my knowledge it sounds like the heater core is bad in your car or cars try replacing it or having someone replace it and see if that works it worked for me now i have cold air again hope i was able to help you with your questionAnswercheck your airflow valves, also check the heater valve it could be stuck open, could even install a manual valve(s)
it may be that you need to replace your thermastat, or coolent level is low wrong mixture
Heater core (radiator) needs to be cleaned or changed
Low coolant? Heater core restricted or plugged? Heater core airbound? Water pump not circulating coolant? Heater control cable not adjusted properly? With mine it was Heater matrix clogged with radiator sealant. The workshop cleaned it and it's start working fine!
It is called homeostasis (internal environment maintained at a constant level) or thermostasis (internal heat maintained at a constant temperature). The overall name for the processes by which temperature is controlled is thermoregulation.
Homeostasis is the maintenance of a constant internal environment in organisms even when there are external changes. For example, the body is able to maintain its same temperature of 98.6 even when it is really cold.
