HEATER DOESN'T WORK WHEN IDLEING

2005 Toyota Sienna

Heater problem
2005 Toyota Sienna 6 cyl Front Wheel Drive Automatic 57000 miles

My problem is that when my van is at idle the heater blows cold air. Whether the van is in Park or Drive. When the van is in motion it does produces heat. It does not produce heat like it should though. Thanks

Check and test the thermostat could be sticking open and also the coolant level and for restricted heater core
