For your XLE's:
When you shift to defrost, the air will come in from outside the vehicle.
If the AC light is on, then the outside air will be conditioned. If you push the AC button off, the outside air will not be conditioned.
All the intake air (fresh or recirculated) enters the intake plenum after passing through the evaporator coil. This could give you cooler air even with the AC off.
