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

Buick has many models, and not all models have the same way to open the fuel tank cap. For most models, press the fuel tank cap when the vehicle is unlocked to open it, then there is an internal knob to twist open. More details about the fuel tank cap of Buick cars are as follows: 1. The fuel tank cap of Buick cars is divided into an inner cap and an outer cap. The outer cap is generally opened by an electronic control or cable control, and very few can be opened with a key. The electronic control button or cable control lever is usually located on the left or right side of the driver's seat, with a fuel pump icon on it. Just press or pull it, and the fuel tank door will open automatically. 2. The inner cap can only be seen after opening the outer cap. The inner cap is made of plastic material; turning it to the right tightens it, and turning it to the left opens it.
I've been driving a Buick for several years and noticed that the fuel tank cap switch is usually located on the inner side of the driver's door, either below the door handle or near the floor, featuring a small button or pull tab. For example, in my old Regal, it's right next to the left leg—just a gentle pull opens it. Newer models like the Enclave might require selecting the fuel filler option on the touch panel. Buick's design is quite reasonable, making it convenient to refuel without leaving the car and ensuring safety by preventing accidental opening from the outside. If you can't find the switch, first check if the key fob battery is dead, or try manually pressing the fuel tank cap, as some models support keyless operation. Regularly lubricating the switch can prevent it from getting stuck, a habit that saves a lot of trouble. In short, don't panic—most of the time, it's not a big issue.
