    A friend at work has this car (I think I go the year right),
    and she says that the heater isn't working well, even with the
    climate control cranked up to max. What are usual suspects for
    this car? Heater control valve? Climate control thermostat? She's
    had the coolant changed regularly.

    First thing I would check would be whether the engine is reaching
    proper operating temperature. If not a bad engine thermostat is a
    possible cause.

    The temp guage is in the normal range.

    If the engine is reaching normal operating temperature then my next
    choice would be one of the vacuum operated doors within the heater
    assembly.

    The temp gauge is not a real temp gauge. It's designed to read normal
    over a wide range of temperatures, to stop people from whining about
    normal temperature fluctuations. Start with a new thermostat.

    Replace tt with t (twice!) and remove parentheses to email me directly.
    (But I check the newsgroup more often than this email address.)
