Electrical system possessed.
The car seems possessed: horn toots, no lights work, cigar lighter no go. Most but not all problems can be linked to the LCM.
We had the LCM rebuilt. Nothing changed.
I bought the Electrical and Vacuum Troubleshooting Manual, FCM-12118-05. What I discovered is that there is no reliable voltage going to the small I/P fuse panel block depicted on the lower left of page 13-6 of the manual, fed by wire 38, which is BK/O (black with an orange stripe).
However, at the engine compartment fuse block, the Lamps fuse, 40A, which feeds wire 38 BK/O, does have 12V. I tore apart both the interior and engine compartment fuse blocks and the wires have integrity. According to page 13-6, between these two is a connector, C224 M & F. Looking at page 151-4, sector E10, C224 should be on the bottom of the connector bracket. In my particular car, however, it is not, instead, it is where C212 should be. But that's no big deal. What is a big deal is that there is no BK/O which travels through
