What must i do for tail lights and dash to work on F150 2006

SOURCE: no tail lights or dash lights

It is possible that they are not grounded properly. The ground wire could have become disconnected when replacing the battery or alternator.

Probably either a bad ground (broken wire, rust) or a bad headlight switch. The brake light circuit goes from the stop switch (Located up above the brake pedal) through the headlight switch, through the light bulbs to ground. The tail light circuit goes through the headlight switch, through the bulbs and to ground. The only things that are in common are the headlight switch (Is this the switch you replaced?) and ground.
Not much, but hope this helps.
Have a super day!

You may have a bad light switch or a bad wire at the light switch.
Only way to know is to remove the switch.

The dash lights and tailights are on the same fuse link. everything else will work like brake lights and turn signals but this one fuse causues alot of problems. Sometimes this fuses isnt marked on your cover so you might have to look in the maual to find the right fuse . some will be under the hood some will be under the dash .

Good luck to you all on finding this little fuse hope you find it before the cops pulls out behind you when its dark :)

you have to check all fuses with a test light both fuse boxes under hood and under dash... if good next to look for is the light switch itself... has any radio work been done to the lately... if so alot of times hooked up wrong will blow park fuse as one of the wires to radio is the park voltage to tell radio to dim down some
