HELP - 02 Ranger - NO BRAKE LIGHTS

02 ranger 4x4 edge plus 3.0. no brake lights. I replaced switch at brake
pedal with no change. I don't know what else to look for.....

You can always start with something simple, like,

HAVE YOU CHECKED THE BULBS ??????????

POWER AND GROUND OK ?????????

POWER AT THE SWITCH ?????????

All are okay.....

So you have power to and from switch, power and ground at the bulbs, and the
bulbs are ok...........

Just posting to keep us busy ????????

your system should work, unless you're just guessing at some things.

yea, every other function works ie turn and tail, and the switch has power
(i can shift out of park, etc) but they still don't operate. all fuses are
good in the entire truck.

Check the hazard lights to see if they work (BTW, does the high mount brake
light work?)... if it appears that they do (from the indicators in the
cluster), physically look to be sure.

check for power on lg wire at the boo switch pin 4

Goes from boo switch pin 4 to connector c212 pin4 to multi function switch
pin 9

comes out MF switch pin 2 and pin 10 and are both going to connector c212
pin 10 and 11 to fuse box fuse f2.3 and f2.7

from there to connector c340 pin 35 and 36 to connector c421 pin 1 and 5 to
the tail lite

considering they are both not working i would concentrate on the wire
between the boo switch pin 4 and MF switch pin 9 and look for broken wire,
if ok look for no power on pin 2 and 10 out MF switch , if no power on 2
and10 and power on pin9 the switch is bad.

Also check fuse f2.9 / f2.13 / f2.10 / f2.21/ f2.3 / f2.7and make sure there
all ok

See that wasnt hard..........

good luck

Oh , i forgot, that $92 for diag

:-)

thank you i will try that

Okay, now that we've covered that, where is the MF switch and those
connectors, and are the fuses listed those that are located under the
hood?
