Show me the right fuse to replace for the parking lights, dash panel light, and tail lights on a 1999 crown Victoria police interceptor


More then likely the lighting control module is bad , But testing would be a good idea. Look at a wiring diagram at http://www.bbbind.com/free_tsb.html .Do you know how to test solid state electronic componets . Testing basic automotive electrical circuits ? The lighting control module supply's power to turn on the lights. Your best bet , take your vehicle to a ford dealer .

dash light fuse dodge sportsman 1978 location


whoa. A 37 year old Dodge. Would that be with the old style Buss brand fuses with the glass cylinder between two metal ends? The fuse panel location should be under the driver's dash. I don't think dodge was too different in locating most items, and that's where it usually was found. Don't be surprised by the small number of fuses, my '79 Datsun has only 5 or 6 fuses on the whole truck.

Why haven't you bought an automotive test light to check your fuses? You don't have to pull them out to inspect, a test light will tell you immediately if the fuse is good or bad while still inserted. Plus you can tell if the fuse is getting power as it should when checking circuits.
To test any fuse with a test light, clip the tester lead to a good ground screw or metal bracket- be absolutely sure the ground is good or the test is invalid-now for a dash light, turn the head/park light switch on. Now one end of the fuse will be hot- use the test light probe to touch one end of the fuse or just the metal clip surrounding the fuse- your test light should light up. Test the fuse by touching the other end. If fuse is good tester will light on both ends of fuse. If fuse is blown, tester will only light on one end of the fuse. If your wiring to the fuse panel is good, you know some of the wires to it will be hot. Some are hot all time (brake lights, horn), some are hot with key in on, run, or start. You just follow the circuit that way, and use a test light or voltmeter, you can't go wrong...well, you can, but you can also learn from your mistakes. Incidentally, you can test all the modern fuses for today's cars in the same way. All of these modern molded fuses have slots called test ports on them, one at each end of the tops of the fuse. No more pulling them out to eyeball, whoops.
