Hello,

My 2013 GS air circulation suddenly sopped working. It used to notice when there are exhaust fumes coming and the light used to switch from fresh air to inside air automatically.

I took the car to Lexus service and they changed the smoke detector but it had no effect.

Have someone else had this issue before?

Interesting. Quick question, is the rest of the HVAC acting normally? Is it resetting all temps to 75*? Do you have third zone climate control or just the fronts?
