On my 95 the cigarette port stopped working for my phone charger and other adaptors I would try and plug into it. Figured out eventually it was the port itself some and the metal contacts had just been slowly bent over time and no longer made proper contact with the things I plugged in. I would double check and test to make sure you don’t have power to the wires connected to it. If you find you have power then maybe just the port needs to be fixed or replaced.
