Cigarette lighter fuse

The one the cigarette lighter is attached to is the Courtesy group 20 amp fuse.

I think the abbreviation is crtsy on it.

However, is more out that just your cigarette lighter.

If that fuse is blown, your dome light should not work, nor your radio. If those work it is not the main crtsy fuse. You may have another problem within the cigarette lighter wiring.

Hope this helps.
