Summer weather has come to South Louisiana. Afternoon highs in the 90's can easily raise the temperature inside your car well above the 100 degree mark. If you're in and put of your car all day, this can make life miserable.  It's customary to crank up the air conditioning in an effort to fill the car with cooler air. I suggest you think in terms of removing heat instead. No matter how hot it is outside, it's hotter inside your car. If your key fob has a button that rolls your windows down, hit it as soon as you walk out the front door.  Start the car & turn the A/C up full blast, then start driving. Roll your windows up slowly, one by one, driver's window last. Leave it cracked 1-1/2 to 2 inches 'til you feel cool air on the back of your neck. You'll be surprised how quickly the temperature drops inside the car.
