    Default 2002 Nissan Altima/NO HEAT

    The temp gauge registers at halfway (normal), the upper radiator hose is hot
    and lower hose is cold. I turn the temp up high and turn the fan on high -
    but only cold air! Any help or suggestions will be most appreciated
    thanks to this fine group

    Could be the coolant control valve - looks like a thermostat.

    Replace the Thermostat.
    The lower radiator hose should be warm compared to the hot upper hose,
    not cold. Radiators are good, but not that good

    Why does everyone automatically condemn the t-stat, a plugged radiator could
    cause the same symptom.

    hmmm, something to think about.

    Default Could be stripped temp control gauge on the console

    my altima was doing the same thing and after spending 175.00 for analysis and troubleshooting at the dealership determined that the temp control gauge that is used to adjust from cold to hot - was stripped. Even though you turned the knob to hot (red) it was still blowing cool air.

    You have to take apart the display console and remove the entire component.

    It could be that.....

    I agree it could be a clogged radiator, but in a 2002? Last year I
    replaced the water pump in my 94 maxima and there was not a single trace
    of rust or deposits in the cooling system.

    Thanks to each of you - felt an update and report was in order It ends up
    being air in the system. A neighbor had experienced the same thing on A
    Volkswagen Vanagon a few years ago. After getting the air out of the
    system gradually, refilling after each small trip and getting a new radiator
    cap, the problem is solved and the heater works fine. thanks again to this
    fine group.
