#4018 of 4019 Gas Saving Tip by using Air Conditioner less
Jul 30, 2010 (1:01 pm)
I found a way to use the AC less often even during hot days. Say your car is parked in the garage than the car it is still cool. You can run the front windshield defroster with the recirculating option on and the air hitting the windshield will become very cool. It will keep the car very cool for a long time so you do not need to turn on the AC. I did this trick and was able to drive to Vegas in a July morning without turning on the AC. Sometimes even if the car is hot you can cool off the car with the AC first and once it is cool turn on the front wind shield defroster and when it is cool turn off the AC.

Unfortunately, most cars built in the last 15 years run the A/C automatically when the defroster is running, to dry up the mist on the windshield. This is true even though the green A/C light on the HVAC panel is not lit. It is likely that this is true for your car, which is why it stayed so cool that day out in the desert. You actually were running the A/C (even though the A/C switch may have been in the 'off' position and the A/C light was not lit), and directing the cold air to the windshield where it then dispersed around the interior of the car.
