Look inside the trunk and there is a ring that you can pull directly on the wall of the trunk on the inside of where the fuel tank door is located. Our Volvo had electrical problems in cold weather and the fuel cap door sometimes sticks when the vehicle is unlocked.
If the gas cap on your 2002 Volvo V70 won't release, try pressing the fuel door release button located inside the vehicle, near the driver's seat. If that doesn't work, check for any obstructions or ice in the fuel door area. If the issue persists, you may need to access the locking mechanism from inside the trunk or consult a mechanic for assistance.
To open the fuel filler door on a 1999 Volvo V70, locate the fuel door release lever inside the vehicle, typically found on the driver's side near the seat. Pull the lever to release the door. If the lever does not work, you can manually push the fuel filler door to open it. Always ensure the vehicle is turned off and parked before refueling.
The fuel door release switch on a 1995 Volvo 850 is typically located on the driver's side, near the floor, to the left of the driver's seat. It is a small lever or button, often marked with a fuel pump icon. To open the fuel door, simply pull the lever or press the button. If the fuel door does not open, it may be stuck or require manual assistance.
Either the fuel filter wont let the gas come in or the fuel pump is broken.
