'01 lw300 electrical problems

I have had a few intermittent problems with the electrical system in my 2001
LW300. First the rear dome light stopped working and then the HVAC blower
started getting flaky. Comes down to poor electrical connections.

The rear cargo light traced back to a bad connection on the diode in the
left side inside fuse panel. Took the diode out and put it back - the light
worked.

The blower motor problem was a burned connector (black 12 cavity hvac
intermediate) located behind the radio. Four cavities were so burned that
they were almost shorting to adjacent connections.

Before I start ranting to Saturn (and trying to repair the connectors
myself), does anybody know if this is covered by any recall?

Looks to me that the contact materials oxidized and developed a resistance
that heated up. It's also a bit strange to put a 40 amp fuse in the
under-hood fuse panel for this circuit and then distribute the power with
some fairly under-sized connections. (I am an electrical engineer)

Thanks for any input
