I have a 2002 Sienna. The temperature gauge operates normally. The problem is that eventhough the gauge shows normal operating temperature the air from the vents is only luke warm. It will take at least 1/2 hour of driving before the air starts to become comfortable. I have taken it to the dealer twice and they say it is normal. I have a Honda van also and warm air comes from the vents in less than 5 minutes. Any suggestions as to what might be the problem?
