I sent you the wiring circuit diagram , please prees on blue link to open diagram
there is no fuse in the circuit it goes from switch to lighter and the other wire on lighter is ground , now there is a 20 amp fuse as you can see
but if this out you want have the switch working at all not just the lighter , but that fuse will be under the hood box .
If you notice on that circuit , the wire goes straight from ignition switch to lighter and it is on constantly 12 volts .
you either have a broken wire or loose ground or just a simple defective lighter , check the power & ground to it ,if you have them replace it
An instrument panel mounted cigar lighter/power outlet receptacle (Fig. 1)is optional equipment on this model. On models equipped with the optional Smoker's Package, the cigar lighter knob and heating element are included. On models without the Smoker's Package, the cigar lighter receptacle is equipped with a snap fit plastic cap and is treated as an auxiliary power outlet. The cigar lighter receptacle is installed in the instrument panel accessory switch bezel, which is located near the bottom of the instrument panel center stack area, below the radio. The cigar lighter base is secured by a snap fit within the center lower bezel. This power outlet has a constant 12 volt battery feed.
Please let me know ,if that work for you
