Where is the fuel tank cap switch on a Buick car?

On older Buick models, the fuel tank cap switch is located in the main driver's cabin, between the A and B pillars, near the pedal area. Press the switch to open the fuel tank cap. For newer models, simply approach the fuel tank cap and press it to open. The Buick GL8 inherits the brand's signature vertical waterfall-style front grille and features three-dimensional LED combination headlights for a sharper look. The body lines are more streamlined, and the elimination of the B-pillar design provides a wider field of vision and easier access for passengers. The body sides also feature chrome metal trim. The front doors open outward, while the rear doors use a sliding track mechanism for opening.
When I drove out to refuel, I couldn't find the fuel tank cap switch for my Buick. After checking the vehicle manual, I finally understood. Usually, the switch is located on the driver's side door panel, near the door handle, where there's a small button or pull ring with a gas station icon, making it very convenient to operate. The car I was driving was a Buick Regal, and the button was right next to the window control switch—just press it to open the fuel tank cap. Remember to ensure the vehicle is turned off or unlocked; otherwise, the cap might not pop open. Additionally, the location may vary slightly depending on the model. For example, in some newer Envision models, it might be hidden in a small compartment under the seat. I recommend carefully checking the gaps on the door panel. This design is actually quite smart, preventing accidental opening and making refueling safer. During regular maintenance, it's also important to check if the switch is stuck to avoid delays when refueling.
