I came here for the same problem. After several trips into the cold I found it. If it is the same as the 2000 Leganza, it is black, located on the drivers side, right knee, pointed down, and attached to the dash,

A non-operating heater could result from a thermostat that is stuck open, keeping the engine from getting up to normal operating temperature; but if that was happening then you would probably have a check engine light on too.
More likely you have either a stuck or broken temperature control for the heater. Temperature controls are either cable-, or vacuum-operated. Find yours in the heater hose somewhere and see whether you can move the linkage on it. If that causes the heater to work, then you have found your problem. If not, then you may have a clogged heater core, which would probably mean replacement (much more expensive than a thermostat replacement, unfortunately).
Btw, your mechanic does not sound too interested in figuring out what the problem is.
