Lighter quit working - 2003 Ford Explorer Sport
I've found the most common problem when a vehicles cigarette lighter stops working is the circuits fuse has blown. Fuses fail from high usage or a power spike in the system. Check your owners manual for the fuse box location and for the layout of which fuse protects witch circuit, and check to see that the fuse has not failed. An easy (but not foolproof) way to check is to pull the fuse out and see if the metal conductor inside has been broken or looks burnt. If your not sure pull out another like fuse and compare them. Sometimes a fuse will fail but you will not be able to visually see it so you can check the continuity of the fuse with a ohmeter or circuit tester or you can replace the fuse and see if the problem is fixed. If the fuse fails again you have a larger problem (I don't reccomend you install the like fuse in the question circuit or the circuit that you borrowed it from now doesn't work and doesn't have a replacemant) It may just be that the cigarette lighter itself has worn out or you might have a problem with the circuits wiring in which you will need to have it checked out by a mechanic with a good knowledge of automotive electrical systems.
It is probably a blown fuse, this happens alot with new cars when a device such as a GPS is plugged in. They arent meant to have that much power drawn.
