SOURCE: how do you replace a fuse for cigarette lighter in 1999 chevy mal

The fuse box for the 99 malibu is right next to the battery, under the hood. It is a 30amp "mini fuse". You can find a chart for which fuse to which circuit, by looking at the lid for the fuse box. This is one of the things I like about the car. If you are using the cigarrette lighter for smoking materials, clean the ashes and residue off the cigarrette lighter (when its cool) with a brass brush, outside the car. Do not let cigarrete material build up in the lighter or it will short.

The starter has one large cable from the battery positive, and a wire that goes to the solenoid (Part of the starter) that becomes hot when the key ignition is turned to start. This also passes through the neutral safety switch. (So it wont start in gear) Not sure if this is what you need, a little vague.
