Leaving windows open just a crack lets hot air escape and keeps the interior from reaching unbearable temperatures, as long as it's not going to rain.
Cool Down Your Car ASAP With These 10 Nifty Tricks

You open the car door on a scorching day and it feels like stepping into a sauna. Here are ten nifty tricks to cool it down fast without breaking a sweat or the bank.
1. Crack the Windows
2. Use a Sunshade
A good windshield sunshade reflects sunlight and drastically reduces heat buildup; side and rear window shades add extra protection.
3. Park Smart
Park in the shade whenever you can, under a tree, a carport, or near a building, even a little cover keeps the car much cooler.
4. Cover Your Steering Wheel and Seats
A towel or a reflective cover over the steering wheel and seats means you won't burn your hands or legs when you hop in.
5. Use the "Fan Trick"
Before starting the engine, roll down one window completely, open the door on the opposite side, and swing it back and forth several times. It pushes hot air out and draws cooler air in.
6. Blast the AC Correctly
Start with windows down and the fan on high to flush out hot air, then roll up the windows and switch to recirculation mode once the air inside is cooler.
7. Keep a Cooler of Ice Packs
Toss ice packs or frozen water bottles in a cooler, then place them in front of the air vents when you return to speed up cooling.
8. Tint Your Windows
Window tinting blocks a good portion of the sun's heat along with adding privacy, just make sure the tint is legal in your area.
9. Invest in a Solar-Powered Fan
These sit on a window and circulate air using the sun's own power, not a replacement for AC but helpful for reducing overall heat.
10. Avoid Black Interiors
Black interiors soak up heat; lighter materials reflect sunlight and stay cooler if you're choosing a new car or seat covers.
These tricks aren't just about comfort, they can also protect your dashboard and electronics.
