I have a 2006 Toyota Sienna LE and even though I set the heater dial to the hottest setting, no warm air comes out. What does this mean? I would appreciate it if you could advise me if you know what is going on.

I guess I would check the fuses first.

I don't have a car maintenance shop that I always go to.
If you're familiar with them, they're flexible.

The information is vague ～
"No warm air comes out at all, even with the heater dial set to the hottest setting."
Does it produce cold air ？
or does it not even blow air ？?

It's a maintenance shop run by a Mexican.
They are familiar with my face, so they are flexible when I ask for help.
Oil change is $30 cash if you bring your oil and filter.
By the way, if your computer goes crazy, this is a Mexican maintenance shop you can walk to.

The cooling system is perfectly fine; when the AC is turned off, the cold air stops but only blows air at about the same temperature as inside the car. The temperature does not change at all no matter what position I turn the temperature control dial to. It is cold in the mornings and evenings.

#9It's Cold Mr.

If the airflow is always there regardless of cold or hot, then the airmic damper is most likely still closed or the heater valve is still closed.

Also, if you have recently changed the coolant or replaced the radiator in an accident, it is possible that the air pocket can't get out of the heater core, but if you first check and see if the airmic damper and heater valve are working ？.

For that year and model, it is very likely that the HVAC Blend Door Actuator component is malfunctioning.
If you disassemble it, clean the contact brush, and apply silicon grease, it will be almost restored.
The difficulty level is not so high, so it can be done if you have enough skills to replace car speakers. If you send it to a dealer for repair, it will cost at least $ 350 including labor charge.

If it's a 2006 Toyota Sienna LE,
take it to a Toyota dealer for service and ask.

While having the oil change done,
the heater dial is set to the hottest setting, but there is no warm air at all.
Ask if it needs to be repaired, and if it's a set problem, they can do the service on the spot.

It's probably the actuator. It's under the passenger dash, so you could turn the heater control to see if it's working. It's probably slowing down, so you might be able to push it with your finger to see if it works ？ I don't know if you can do that. You might have to remove the undercover to see it.

Thank you all. It is now fixed.
I found a number of videos on Youtube, so I did it while watching them. I was very impressed when I saw that the arm started to move after the repair.
However, it did not go as smoothly as in the video, and I had a hard time. I was exhausted, but it was a great feeling of accomplishment.

crack crack crack ！ Good for you. Cars are basically designed with repair in mind, so if you learn a little and get the hang of it, you can do repairs that would be considered quite difficult even for an amateur.
