Lexus RX330 Heater problem

2005 Lexus RX330 Heater problem
My heater works fine when the car is moving but when idling at a stop light cool air comes from the vents. When I start driving again it heats right up. What is causing this?

Check your antifreeze level, not just in the expansion tank, but in the radiator as well.

Also inspect the sides of the radiator for evidence of leakage. There is a fix for radiator leak done via warranty due to defect.
