Lighter not working.what fuse is - 1999 Ford Crown Victoria

Check for battery voltage on the cable at the lighter, If ok replace lighter , if no voltage check fuse and connection from fuse box to lighter.

door locks and cig lighter ARE NOT on same circuit. Maybe lighter is broken and blowing fuse.

the cigarette lighter fuse is usually the radio,clock ,instrument panel illumination fuse as well .If these other items are working ok i'd have to say the cigarrette lighter heat element is burned out or there is a loose /disconnected wire to the cigarette lighter socket

Hi Jal, I would think all 3 lighter are on the same fuse. There must be another fuse box inside the vehicle,possibly in the kick panel area.

The lighter socket or the element.
Check the element for burn marks and the socket for debris blocking the contacts.

check all the fuses with a test light at the fuse panel as you may have more than one fuse bad.replace the fuse and operate the rear hatch and if it works then and the fuse isn`t blown then you probably have a lighter assembly that is blowing the fuse.to find out which one activate each one separately and check the fuse after trying each one before trying another one.the lighter that blows the fuse you may have to replace the lighter element or the lighter socket to stop the fuse from blowing.

When your lighter lit on fire it could have melted the casings on the wires shorting them together. This would cause the fuse to blow every time you use the lighter. Also it is the same fuse for both the lighter and obd (which in your owners manual will be called Data Link Connector, or DLC). Replace the fuse but don't use the lighter. When you plug in the DLC it should work just fine then try the lighter. If fuse blows you have to fix the wiring to the lighter or possibly the lighter socket.

check the wiring behind the lighter and recheck fuse panel for a designated lighter fuse or the lighter housing may be bad if u have power to the lighter than replace lighter unit any auto store sells them

The fuse box cover should tell you which fuse controls the lighter. Also, I've seen it where the people forget to hook the harness up to connect the lighter unit

The front lighter is powered by fuse 24(20 amp) in the interior fuse panel and the other lighter or power point is powered by fuse 12 (20 amp) in the under hood fuse box
