Driver kick panel FB01 CPU circuit
I'm trying to find out what all is on the CPU circuit that sits behind the kick panel at the drivers left foot.
I'm finally driving and learning issues on the 91 vert I bought from my father. Drove it yesterday for the first time and found the interior lights do not work (door light, dome light), the idiot cluster blinks dimly and constantly, the fog lights do not work. My father told me the dome and door lights didn't work due to a bad door switch. I swapped the door switch from my project turbo vert with no change. I haven't checked fuses yet and my shop manuals and wiring diagrams are buried in storage. I've done some searching and also from experience I know that CPU controls a lot of the lighting and accessories. I'm hoping everything wrong with mine is due to that CPU going bad. I have a 90 vert project car sitting right next to it and can swap them out.

Found the 7.5 Room fuse blown and the fog light switch is bad. Swapped the switch from my project car and I'll try cleaning up the bad one with no continuity.
Strangely the fuse replacement has the idiot cluster behaving much better. No longer dimly and slowly flashing. Clock is keeping time. Airbag idiot light is dimly lit. I'll pull that fuse and see what's what.
Drove the car for a good portion of the day and the fuse never blew again. Hopefully it was a fluke thing.
