We have a 2000 Villager which blows cooler air while idling, and then warms up when the engine speed increases. I talked to our mechanic and he thinks the cooling system may need to be flushed - the heat comes from warm engine coolant circulating through the heater core. If the cooling system is flushed and the passage ways in the heater core are reopened allowing warm coolant to flow freely, that may solve our problem. I'll have this done, and do a second post with the results.
