Cigar lighter not working in 05 ford focus 1.6 diesel the fuse seems alright is there an inline fuse as well ?

In the diagram, you can see cigar fuse. Should be interior fuse box.

Ciggy lighters generally have an independent fuse. Either in the engine fusebox or more commonly under the dash as an inline fuse. Normally directly behind the fitting. Fuse No 12 @ 20amp mate.

No you must get behind the lighter element to remove the large screw on barrel nut that retains it to the dash.

usually at bottom os steering wheel behind a panel about knee level

the fuse will be 1 of 3 auxpwr cig radio
if your radio is not working also try the radio fuse, some older vehicle have the cigar lighter tied into the radio fusable link

1. Check the fuse #41 in the cab fuse panel.
If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :

2. Are you using a device ( MP3 player, GPS, etc ) to test that it is not working, or a meter ?
- Could be the fuse in the tip of the DC adapter for the device is blown.

Focus 1998-05 fuse 46
Focus 04-07 fuse 39

yes their is a fuse and its clearly marked on the back of the fuse panel cover

I'm not familiar with that car, but you might be certain they have a proper ground. Also, many cigar lighters have a fuseable link on the back where the power plugs on. I've seen the links corrode up and quit working. You merely crimp where they attach and it will work again. Some stereos (after market) have a separate fuse inline (not only the vehicle radio fuse). You might also just change the fuse. I've seen some that looked good, but had a hairline fracture and therefore did not conduct. I hope this helps you find your problem.

I think there should be another fuse box located inside the vehicle possibly under the dash panel on the Nearside.
