Sam,
Most of the fuses are the originals (25 year old and aluminum). I've ordered the new style brass ones and will replace all as I clean terminals.
The CCU was resoldered about 3 years ago.
I've got low vacuum and a noisy pump - replacing it this weekend and then checking for vacuum leaks.

I've got a plan and I'm sure I'll get it fixed.
Question is:
"Why does killing and restarting the engine make it work"?
Often if the system is working and you stop and restart soon, it will quit working. This is the baffling part that my wife is so smug about because her method works and I can't explain why.

PS: What's the trick for removing the plastic fan without breaking to replace the motor? The entire assembly new is too expensive. The motor is reasonable but it looked like I would probably break the fan trying to remove it.
