    I have a 1988 accord with no heat when the gets hot the hose to and
    from the heater core gets hot but i still have no heat. the heater
    cable does move butterfly valve. thermostat works fine, car does get up
    to normal temp.

    blockage or insufficient coolant. for blockage, try a reverse flush.
    for leakage, check inside radiator for fluid level - if there's a leak,
    the expansion bottle won't show it because air sucks back through the
    leak rather than fluid from the bottle.

  3. In my daughter's 1993, it was the adjustment of the mixer box, at the very
    bottom of the center console. I know yours may be different, but see if
    these directions apply...
    Remove the cover on the passenger (right) side of the center console. You
    need to move the carpet out of the way, and the cover is mostly comprised of
    a duct, but it comes off easily. IIRC there are one or two screws, and it
    sort of pops off. You will see two cables; one goes to the temperature
    control knob and the other goes to your heater control valve in the engine
    compartment. Turn the heater control valve and watch things move. It will be
    obvious what is or is not in adjustment; the adjustments are done by
    unclipping the cable housing restraints and reclipping when the cable
    housing is in the right position. (It really is easier to see than to

    If the cable to the heater control valve doesn't want to move, you can try a
    spray of silicone lubricant on the top of the valve (near the firewall) and
    exercise the valve with your fingers. If you have to replace the valve, be
    smarter than I was and pad the edge of the catalytic converter heat shield
    before prying the hoses off. I almost needed stitches for that one. If my
    wife had been here, she would have insisted on them :-( I was just happy I
    hadn't cut any tendons. Anyway, be smarter than that.
