Correct. The brown wire goes from the fuse panel directly to the A/C switch, unless a previous owner did something to it. The wire connection at the fuse panel could be corroded. Another possibility is that someone may have moved that brown wire to another fuse.
quote:So couldn't I then just bypass that brown wire all together and make my own wire from the fuse box prong directly to the AC switch
Yes.
quote:No way I can trace that brown wire all the way because goes up under the dash somewhere.
It's buried in the wire loom. You would have to cut the black tape wrapping and hurt yourself again.
