My daughter bought a ‘98 Beetle as a project car. The previous owner cut a number of wires and portions of the chassis electrical system don’t work, like the fuel door release and the power windows. While we hunt down the cut wires or whatever is keeping this from working, is there a way to manually release the fuel door?
There should be a plastic access panel in the boot (or "trunk" if you're in the US) near the rear light cluster behind where the fuel filler door is, pop that off and you should be able to see the cable and you can pull that down and it should release the catch and open the door.
Alternatively you can use a credit card to wedge in where the catch is and release it that way but tbh it's fiddly to do that way - pulling the cable is much quicker and easier IMO.
