Brake and tail lights not working, probably a fuse but we don't have the owners manual to determine which fuse to check

You can see fuses in diagram, hope it's large enough to read. The B at bottom right, brown wire carries voltage for tail lamps. At the rear, brown wire is voltage and black wire is ground for tail lamps. You can use test light to check voltage and ground, both. If the other rear lamps work, ground is probably ok. As you can see, the main light switch signals the Lcm. Your owners manual should tell you which fuse is which. owner.ford.com should have your owners manual, it's free to read online. good luck

There is a separate fuse for the tail lights. Check your owners manual if available for it's location. Usually under the dash on the driver's side. If you don't have the owner manual, you can look it up online or check the fuses individually, looking for the one that is blown.

Hi Jimmy.

Most every circuit in a car goes through a fuse. if you look in your owners manual for the particular vehicle you drive, you should find a listing for a fuse for brake light or brake lights. The tail light being OK should not have anything to do with the brake light. They'll be different bulbs, or, at worst, different filaments in the same bulb, and on different fuses. The brake and tail lights are distinct because otherwise, if you had your tail lights on at night, no one could tell you were pressing your brakes.

If you were meaning that the bulb for the brake light in the tail cluster is good, that also will point to a blown fuse. Check there first.

Good Luck

the tail lights and brake lights are on a different circuit so if one goes out you still have the other was your car serviced recently the mechanic might have taken it out so you can come back to spend more$$$ check the owners manual for the fuse value EX. 5amp -15 amp? and put it in the open fuse space in the power distribution box behind the battery this will probably fix your problem and unmask a rotten mechanic if you don't have the owners manual you can search it on the net and look at the power distribution box diagram it will tell you the fuse value that should be there LATER MAN!

Blown bulb.

Look in your glove box for the owners manual, Check the manual for the location of the fuse box and check the head light tail light fuses.

First let's determine which brake lights are not working. Does the high mounted brake light work? Do both left and right brake light not work? If none of the brake light work, the problem could be the brake light switch at the brake pedal OR fuse #12 in the underhood fuse panel.
If only the bake lights at the corner lamp assembly don't work, check fuse #34 in the rear fuse panel.
The module your are referring to is the circuit board located in each of the corner lamp assemblies, check on website www.compnine.com for the part number of this item. I don't believe this is your problem though.

Why would it be a fuse?
You have front parking lights? Then no fuse

If it was a fuse ---would that fix it -- NO it wouldn't
Why do fuses blow?

Have you even removed the tail light housing & checked the bulbs,
or checked the sockets for ground or under truck for wiring
harness issues?

Don't need a manual to check all fuses under the dash &
in the box near brake booster

Look at fuse #18, a 15 amp fuse, in the fuse block. This fuse powers both the tail lights and instrument cluster lights. Usually both of these light systems are powered by the same fuse so when your cluster isn't lit up you'll know right away that your tail lights aren't working as it's not safe to drive without tail lights. Your brake, turn, and head lamps are powered by different circuits. Hope this helps and good luck!

CHECK ALL LIGHT BULBS IN THE BACK. PROBABLY HAVE A FEW BAD BULBS THAT ARE BURNT OUT COMPLETELY. CHECK LICENSE PLATE LIGHTS ALSO. CHECK FUSES TOO TO MAKE SURE THE TAIL LIGHT FUSE IS GOOD.
