Basically, they had problems with ground cables somehow connected to the
self-destruct system. My guess is that this is some kind of
communications system. Vandenberg has a lot of moisture and that is
probably the ultimate cause.
The satellite is DMSP satellite Flight 16. DMSP is a low earth orbit
weather satellite. They are basically similar to NOAA Tiros birds--they
have a few different instruments. This satellite is replacing a satellite
launched in 1995. The satellites have a 3 year design lifetime and the
1995 one is therefore past its design life (I don't know why their design
life is so short, but I guess that it's because the sensors degrade fast).
Eventually both the NOAA and military systems are supposed to be merged,
with Europe joining in. I don't know the specifics and wonder why it has
not happened yet, since the decision was made around 1993 or so. But it
is still in the cards.

A very brief history of the program is here:

A detailed history of the DMSP and its spooky predecessor will be
published in Quest in the next year or so (not by me).
