Well, I pulled the dash pod out of the Westy and fixed my clock.
It turns out that the flexible circuit board had a trace broken
somewhere (never did find it).

With a little care, the circuit board CAN be soldered successfully.
I soldered a jumper wire from one end of the broken trace to the other
without any difficulty. It'll be nice to have the clock working again.
It's not that I care so much about what time it is. It's just that the clock
is SO right in front of me when I drive, and was SO obviously broken.
