I have no lights on my 94 crown vic fuses are good

1) you must connect the switch in series, in tha way you will not have this problem, and you must add of course the relais, for to avoid the spark, and arching by load .Now you have connected in paralell.

God bless you

The diagram is part of the owners manual, you can access a free pdf copy HERE.

No timing belts on a 94 Vic. It's timing chains and it's not easy.You'll need a manual and some skill. Good tools, too. don-ohio

First check fuse for brake light with test light if fuse is good test brake light switch under dash with test light if you dont understand how to do the above contact me at [email protected] title the message crown vic problem

Easy stuff first. Try replacing the #9 fuse on the interior fuse panel. This fuse protects the instrument panel, license, parking and tail light circuits. The panel is located under the dash to the left of the steering column. You will need to pry off the cover on the panel to access the fuses. The fuse you want is a 15 amp fuse located directly under the turn signal flasher. It should be easy to figure out which fuse it is because it will be 'blown' or open. This is easy to determine just by looking at the fuse once it's removed. And, if you aren't sure what's what, I'm sure you can find a diagram of this fuse panel somewhere on the Internets if you look around a little. I took this info out of the Owner Manual from my own '94 Vic. If this doesn't solve the problem I would suggest taking your Vic to a shop and letting them take a look at it.

since the fuses are ok i would try the servo this is the piece that looks like two face. it has a solid back on one side and a rubber front on the other it should be around your master cylinder. check to make sure that the wires arent frayed or have come loose.

look under the hood in the big fuse panel and look for High beam headlight relay the relay is more than likely bad

Easy. Does your Vic have a five number keypad above the driver's side exterior door handle? If so the you got key-less. If not, you do not.

They are changed from within the engine compartment... at the rear of the headlight bazels... if it's the side on the battery you may have to remove it.... also don't touch the bulbs with your fingers as that shortens the life of them.

Try checking all the grounds for the radio, over time they can weeken. If that doesn't work, put in a new ground wire with a heavier gauge, that should fix it. It sounds like a ground problem.

Good luck, Daniel
