HEATER

1999 Toyota Camry • 2.2L 4 cylinder 2WD Automatic • 388,000 miles

I have to start car and let temp go to normal. My Heater only works when car is not moving. Once I start moving temp goes back to c, and heater blows cold. Can You please tell me what the problem is?Thanks

First thing is to check the coolant level.
As the coolant leaks out and the level drops the heater will lose its ability to heat because the system doesn't have enough coolant. Let me know how this checks out. Another problem could be a faulty heater control valve, but lets take it one step at a time.
