Air vents blowing too warm when AC is off

[spookybathtub]

Hi everyone.
I recently bought a 2007 Hatchback Yaris. I try to avoid using the AC whenever possible, to boost fuel economy. One really annoying thing I have noticed is that when the AC is off, the air from the vents is always much warmer than the outside air. I live in beautiful southern California, so summer evenings are commonly 60 - 65 degrees (F). But the air from my vents is uncomfortably warm - probably around 80 but I haven't actually measured it.

I know this makes sense, because the air is passing through the hot engine compartment, but it just seems more extreme than any other car I've driven. Does anybody else notice this, and has anyone come up with a solution?

Of course I could just open the windows, but I prefer having them up for audio reasons.

you've got strange priorities

There MIGHT be a problem with the heater circuit that is not really turning the heating off. You can also make sure that the temperature adjustment is at the maximum cool position and then make the checks on your system, that it is actually setting those controls at the devices to the lowest positions. The outside air passes into your cabin from the intake behind the hood and would not be all that warm through the vents. you could also try slightly opening at least one window in the back to allow more of the cool air to enter the cabin.

turn the switch to recycle...itll drop the temperature a bit.
