08, LTD with auto front and rear climate control.
outside temp 85 degrees, car sitting in sun all day long, inside temp must be about 100 degrees. Air is on recirculate when engine turns on. Why?? Doesn't it make more sense to pull fresh 85 degree air then to recirculate 100 degree air?
Driving with AC on, outside temp 85 degrees, temp for driver, pass, rear set at 73 degrees. For no reason, pass. setting goes to "max heat"
Another time, rear temp goes down to 68.
(did not touch any of the controls).
Any explanation or solution to this??
Yeah, your scenario 1 has been my frustration with my 09 since the warmer temps came around. I have the exact same problem. AUTO off, AC off, and I turn the RECIRC off, yet I can turn the car off, and then on again, and the RECIRC automatically comes on again and blows the steaming hot interior cabin air in my face. I spent C$40 K to have to push the recirc every time I get in the car???
This only occurs if the temp setting is colder than interior cabin temp. I can understand the recirc coming on IF I have the AC on, because recirc'd AC air will cool the interior much more quickly. However, I am more a fan of fresh air than AC, so I often have the AC and AUTO off, and therefore find myself driving a minute or two before realizing that the temp is rising and have to push the the recirc button. If Toyota wants the recirc to be automatic, then it should only come on if the AC is on, not if the AC is OFF! OR, it should only work automaticaly in AUTO mode.
Anyway, I have my first appt with the dealer Thurs, and besides the rotten egg smell that I am getting every time I accelarate (even if I have windows closed, AC on and recirc on, believe it or not), this recirc isssue is at the top of my list.
We'll see if they have a fix, but I'm not holding my breath.
