I have used the search function for the past few days. I appologize if this issue has been covered. I can't find it anywhere.
I have an 08, EATC, 200K miles.
Over the last month, the climate controls work normally in auto or manual. Then after a period of time (never the same frequency), air stops coming out of any vents. I can select any combination, no appreciable air flow.
This is with heat or a/c, auto and manual - same results.
I have to turn the flow up to high and rely on air that is leaking by the closed vents to warm or cool the car. It seems like there is a main damper or something that is preventing discharge from the fan from entering the cabin.
After a period of time, I get back in the car and everything works correctly again (for a period of time).
I can hear the fan running at all times.
