On the GS, the CIG fuse covers more than one thing (the other lighter socket for instance) so if the other one still works, it is probably the socket fuse link. Again, on the GS, it also powers the display for the clock, if that is off, then the CIG fuse would more than likely be culprit. The LS may be different, but they tend to follow similar principles. Anyone confirm that who has LS wiring diagrams?
