Just the other day I had multiple issues pop up. heat/cooled seats stopped working(switches do nothing), auto headlights stopped working, power locks fail to automatically lock, the door ajar indicator fails to display when any door or hatch is open. courtesy lights fail to come on when door is unlocked or opened. the radio started working after a year and a half vacation. i took the fuse panel out and tested all fuses and checked for cracked solder joints. im leaning towards the smart junction box, but wasnt sure if that had any affect on the seats. its a 03 eddie bauer expedition. thanks.

get yourself a service manual
Ford workshop manual on DVD. Can be obtained from seller "morpheousking" on e-bay. Cost about $15.00 Much better than Clymer, Haynes or Chilton and also includes wiring diagrams
Don't waste your money on a Clymer, Haynes or Chilton Manual.
It is well worth the $15.00 just make sure you get the DVD for your year as the seller has different DVD's for different years

Possible loss of power in one of the circuits that go thru the ign switch

Hey bedrck46, do the 2nd gens have the GEM? I'd look through "my" diagrams but I'm currently installing flooring in the computer room and it is a mess. If it does it sounds like he may have a GEM issue.

No GEM in the second Gen's
I looked at the prints and his issues and many of those issues get power thru the Ign switch

now the back wiper stopped working. it still sprays fluid. and today with our wonderful minneapolis snow, i switched it into auto 4x4, and it didnt seem to ever want to engage. im thinking the fuse panel with so many unrelated failures. but the newest version is around $280, so i may just wait till it doesnt start at all.
i swapped out the fuse box, and no change. am thinking its in the PCM. i have spent hours going over the wiring diagrams to find a common tie, but that seems to be the only one now. going to bring it in tomorrow for the $95 diag from ford to see if they can confirm or pinpoint the exact issue.
i got the dvd manual, where on the diags are you seeing feeds from the ignition switch? my eyes got buggy from spending hours looking through them.

Look in the power distribution pages 13-14, 13-15, 13-16

Ask yourself this, why would the powertrain control module have control over the seats?
