Question about 2006 Toyota Sienna
The hot air blowing from my heater turns cold when I stop driving (it was blowing fine while driving). Once I start driving again, it turns back hot.

You have a broken wire connection between the temperature control knob and the circuit board behind the center dash console. Vibration causes the failure and once the control knob gets loose the solder connection fails.
For someone that knows how to remove the dash unit and can re-solder a couple of new wires this fix should take no more than 1 hour. Make sure that you apply loctite to the heat control knob spindle nut when you re-assemble it.
The dealer quoted me 750 dollars to fix this issue and I found out that it's a common failure for this year. I fixed mine virtually for free but it took some tools and about an hour of my time.

If the engine temprature does not reach the normal level as it used to, it may be the coolant thermostat.
Iif it does, it could be air diverter gates not working properly, cold air blowing at a a light could point to that. The diverter gates are located under the dash.
It also coul be the valuve that controls the water to the heater core, but unlikely cause of the cold air at a light.
