I'm a little late with thoughts on this one but here's my input......I  
think you may have two issues....1) the fuse block and 2) the blower  motor.
 
Fuse Block - while they are not cheap to buy, they aren't terribly  
expensive either and the amount of grief and turmoil that an old fuse block can 
 
cause is, in my experience,  just not worth saving a few bucks and getting  
out the sandpaper when things go screwy.
 
Blower Motor - since your trouble initially began when you turned the  
blower motor on during a rain storm, the culprit may have been (or still is) a  
blower motor that is pulling too much current when it operates (regardless 
of  whether it's raining or not). 
 
One quick way to prove this would be to remove the fuse from the white  
wire/green wire fuse slot and connect an ammeter in place of the  fuse.  Start 
the car (or turn the ignition to "on") and operate the blower  motor.  Dan 
Masters states on page 26 of his Electrical Maintenance  Handbook that the 
"green fuse" (the fuse between the white wire and green wires)  should see a 
total of 16.7 amps when every load on that circuit is on or  working.  In 
particular, he says that the blower motor should draw 4 amps  when working.  
Given that the temp & fuel gauge will draw about .4 amp  when you turn the 
ignition on, the blower should add another 4 amps when you  turn it on.  If the 
blower motor is drawing significantly more than 4 amps,  you've got at 
least one culprit.  The fuse block may still be  partly at fault; a heavy 
current draw from the blower may just be  the trigger.
 
The only way to really get to the blower motor is to remove the  heater box 
which is really a pain!  I think I'd try to find a simple  cause for the 
high current draw like bad ground, crossed up wires...heck,  maybe the problem 
is in the blower switch??
 
Good luck,
