Doesnt heat up
SOURCE: focus 1.8 td 2000 ,no heated screen , cigarette lighter or horn
could be fusesm one maybe more
SOURCE: cigarette lighter won't work fuse ok lighter base ok
I would put a red volt meter lead on the middle and a the black lead on the outside. If it checks above 12 vols, the lighter itself is bad. If no voltage is present, you have to check all the positive wires back to the battery. If those are all working, you have a bad ground.
SOURCE: in my 1994 ford mustang the cigarette lighter
Check for power at the fuse on both sides of the fuse if there is power check the wire going to the lighter if there is power check for ground if all are there you may need a new lighter if either power or ground are not present trace the wiring to find a short or bad wire.
