2005 Honda Civic EX heat is only hot while driving

Asked by Jan 01, 2015 at 11:32 PM about the 2005 Honda Civic EX Special Edition

Question type: Maintenance & Repair

As soon as I stop at a light, stop sign or at an idle it is freezing cold air.  I have had the
thermostat and water pump replaced but still not fixed.  (My check engine light has also
come on and was told the O2 sensor needs to be replaced- not sure if this is related)

your heater core needs to be flushed or changed

Have the computer scanned at your local auto parts store and post the trouble codes here. Most stores will do it for free. No, an O2 sensor (oxygen sensor) problem will not effect the heater operation. I suspect that the heater core is restricted. When you accelerate the water pump spins faster and pumps more coolant. This increases the pressure of the flowing coolant and is able to force the coolant through the partially clogged heater core. When you stop no coolant is able to get through the heater core so the heat stops. HTH. -Jim
