2003 Mountaineer, 48,000 miles. Daughter got into it to come home from work. No radio, instrument cluster, message center, memory seat or windows. She drove to an advance auto parts, they ran a diagnostic. Only thing that comes back is 'faulty fuel level sensor'.

She got home, I checked fuses, found nothing blown in either panel, in the manual, I don't see a fuse that would connect all those anyway. Any ideas or help would be greatly appreciated.

 

Check for coroded wire/cable close to + battery connection (inside rubber casing)

 

I ran out and checked. The + cables look brand new. Either it has been recently replaced, or was meticulously maintained before we bought it. Wondering if it could be a relay. Also, now that it's dark, we find there are no interior lights (map, dome). The cluster panel lights work, even though the cluster itself is dead. No puddle lamps either, on the mirrors. However, the power mirrors themselves do still work. The headlights work but the auto on/off of the headlights does not.

Thanks for taking the time to reply. Every possibility is worth checking.

 

Time to break out the VOM and do some continuity testing

 

Apparently it resolved itself. Went out rechecked fuses, relays breakers, everything looked good. Locked the door, thought I would try the door pad to see if that was out as well. Input the code, puddle lamps came on. Opened the door, lights came on, started it up, instrument cluster worked, radio came on. So in short.... I dunno.
