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 any of these connectors in that area of the car. (Yes, C224 has eight pins, and the other colors match the drawing on page 150-6.
So here are my questions-
1. Does my vehicle have a connector between the engine compartment wiring and the interior wiring for this wire? The answer is probably yes, because they always make the harnesses in several pieces....
2. Where is this connector? Is there a change order which mentions it?
3. How do I fix this? I'd rather not run another wire, but if I have to, I will.
Thanks! I really look forward to some help- I could have fixed this if the manual had been accurate.
Wire 38 Black and orange also comes off of the voltage regulator and goes into two fuse links (gray plastic on wire. Check to see if you have voltage to both sides of both links, one may be blown.
Check it out and let me know your results when you can.
