'96 ford Crown Victoria....No hazard or brake light no turn sigal

It is usually located near the fuse boxunder the dash on the driver's side. Simple way to find is go buy a new one and ask the counter peson to show the diagram showing its location. Cheaper than have a mechanic do it.

This is normal, your car is equipped with Daytime Running Lights so just the headlights will be on at all times. Its a pointless safety feature.

you never said if you have a good ground to the taillights, check the sockets

you must replace the multi fuction switch! also known as the turn signal switch! its common on ford crown vic!

The fuse for these lights sound like it may be blown. Find you fuse panel, your owners manual will tell you exactly which one it is, sometimes it is printed on the panel cover. Replace with the same size fuse.

If all other lights are working properly (brakes, hazards and tail lights) there is a good possibility that it is a flasher unit. The flasher unit is usually near or in the fuse block and is usually a small round about an inch in diameter - can be plastic or metal covered. Grasp it firmly and pull straight out on it. There are 2 contacts at a 90° angle that fit into the board. A new unit should be under $10. To reinstall it - just align the contacts with the slot and push it firmly back into place. On most vehicles the hazard flasher unit is the same device but a separate unit. If you turn on the hazard switch and those lights are working you will be able to hear a click as it turns on and off. Once installed - activate the turn signals with the key on to see if it clicks.

Check all the bulbs at tail end for parking and brakes, test grounds and harness for trailer. Check fuses. clean batery terminals, Re instal head light swich properly and make sure all wires conect.

well makes no sense turnsignals are on ignition switch fed fuse and brake lights are on 24 hour fuse.. to me sounds like bad turn switch... it handles turn signals also hazzards. and brake lights have to go through the turn switch also... it is common problem.. combination switch is what they call it.. not hard to replace either....let me know

The hazards are on a seperate fuse to the indicators, on the inside of the fuse box cover it will tell you which fuse it is, simply replace it with one of the same rating and your hazards should work, if not come back to me

check the plug in the trunk lid mine did that and the plug was completely disconnected, yours may just be loose, or have a broken wire
