ive had 2 fix a few lighters already... one in a baja & one in a legacy gt. first look at the fuse make sure that's not the problem then acsess the wiring harness behind the socket to make sure its not stock wireing that is bad. if ur all clear up to there the problem is in the cigarette socket itself. u can eather get a new one, or fix it like did. if u look at the back of the socket theres a small black wire connecting the "tip"(from the back) this is small wire connectong the possitive side of the lighter. due to all the current used to heat up the lighter heating element this small wire would be melted. u can us a ohms reader to see theres no connection from the "tip" to the contact where the cars harness plugs in. simply replacing this wire should fix u up just fine.
