Do you use the water heater when you use just cold water?
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 However, if water is drawn from the hot faucet- even for a few seconds- hot water IS withdrawn from the heater, and fresh cold water drawn in to be heated- even if the hot water did not make it all the way through the pipe to the faucet- and the water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.

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.

Ac lines are all cold and sweaty but blowing only hot air inside what causes this?
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.

How do you fix a heater that wont blow air in a 94 Nissan Sentra?
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.

Where is the defroster in a car?
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.
What makes your windows keep fogging up even with the defroster on a 1992 Bonneville?
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.
