LIGHTER FUSE

Location: Instrument panel fuse block

Type: 20A Minifuse

Feeds: Circuit 740

If one of the following Systems is operating normally, the fuse is most likely good:
^ Cigar lighter

If the fuse is blown determine the cause of the blown fuse and repair.

Replace fuse as needed.

GROUNDS
Before checking the ground circuit from the faulty component all the way to the ground stud, check the circuit from the splice pack to ground by testing some of the other subsystems grounded by the same splice pack. If the other subsystems function properly, it is most likely that the path from the splice pack to ground is good (or at least one of the paths is good with redundantly grounded splice packs).

I/P SPLICE PACK #1

Location: Taped to harness behind I/P cluster.

The systems grounded by I/P Splice Pack #1 are grounded redundantly with I/P Splice Pack #2 at ground point location D (I/P chassis ground). If one of the following systems is operating normally, the ground circuit is most likely good.
^ Transaxle shift program switch
^ I/P dimmer
^ Cruise control
^ Headlamps
^ Cigar lighter element

Check for OPENS/SHORTS.

Repair as needed.
