Reduced Dash Airflow With Heat On?

If you own a 2024 Tacoma, could you please try this and let me know what happens:

1. Turn the temperature control to full-cold (“Lo”) and the fan speed to full fast.

2. Set the blower location so that air is coming out of the upper dash vents only—the ones that blow on your face. (No defroster, no feet, etc.)

3. Turn the temperature knob to full HOT.

What happens to the airflow coming out of your vents? Mine drops off to a fraction of the airflow that I get when the temperature knob is full cold.

If I change the air location to defroster or feet, I get a ton of airflow again. I just get very diminished airflow from the main/front dash vents when the heat is full on.

Wondering if they’re all like that or if I need to go chew Toyota out.

 

Yup mines the same way
