TJ brake light problem, Help needed please.

A friend has a 98 TJ and the brake lights don't appear to have power.

The signals work and the emergency flasher works but the brake pedal
doesn't.

I haven't crawled under myself because I am not able, but from the
schematics (I only have the 2003 TJ wiring schematics, not the 98 one)
it appears the pink wire should be hot all the time from the fuse. My
friend says he sees .5 to 1.0 volts there with my meter. None of the
other wires are hot and the switch is dangling now (removed) so it
should be 'on'.

The fuse appears to be fine.

Is there something else I am missing that might crap out the power to
the switch?

Thanks for any ideas,

What type of bulbs are installed? Gene

The front signals have those push in style, didn't open the rears.

I was checking the front one for heat damage due to a fender bender at
one time crushing the fixture. The wiring looked perfect up there so I
went looking elsewhere.

the white with tan wire at the switch is the one that sends a signal to
the rear lites but not before it goes thru the multifunction switch if i
remember correctly
i also have seen the lite covers on the rear lites cause a bad ground

That is the trick, there isn't any power coming to the switch on the
pink wire so nothing going out the white/tan.

I have heard of the flasher and multifunction switches interfering with
brake lights which is why I first checked a previously damaged front
socket's wiring for heat damage from a recent accident. It seems fine.

I am looking for something else on the power side.

Hmm, front impact. I wonder if the wiring harness behind the fuse panel
could have pulled the wire loose behind the fuse or when they changed it
they pushed too hard or the suckers just fall out like the recent door
switch thread. Have to check to see if there are two sockets I guess.

Thanks, any more ideas are welcome.
