Hundy is being a cold hearted B$&#%: No air flow from center vent

[cardyjones]

Hi guys,

She's so cold, she's so coooooold.

02 w/ nav and digital climate control.

So for a few days, with heat set to 75 and manually set flow to center/floor, fan to medium, I notice a little issue.

1st ten minutes of drive, air flows out of center vents, then it stops flowing. Blower is running, just no air from vents.

Thought this system was electronic, not vacuum
Based.

Is there a way to reset climate control brain?

It's probably thinking it's reached it's temperature and done. When I leave my climate on "auto" it does all kinds of odd things. Try turning it up to max.

Have you check your rear thermistor? My front thermistor wasn't hooked up and the heat didn't work up front. (Rear worked fine) Hooked it up and the climate control works perfect now.
I found the info in the "anemic heater" thread. Sorry no link, I'm on my phone.

Hmmm,
So the climate control is set on manual, not auto.

Auto setting doesn't help matters. Can feel warmth from vents, just not airflow from center vents while blower is running set to "upper body"

Does a vacuum leak affect climate control system?

Even hi fan setting, just a little flow out of vents....

Again, airflow is fine when she is first started, but ten minutes of driving and it's barely blowing....

FYI used auto setting for heat this am, seemed to work better at heating cabin. Guess I will just trust Mr, Toyoda from now on.
