Idle and cruise, Help please.

[randrews@post.cis.smu.edu (Robert Paul Andrews)]

OK guys,
My cruise has now stopped working.  I checked for the vacuum hoses, all
seem to be alright.  Now, A week or so a go, it rained, and I had my fuse box
cover off, (I know, pretty dumb, but I forgot) and it rained in there.
When I got to my car, my fan was running on high and the fuel pump was running
all the time.  I pulled the fuse for the fan, and well, had to leave
the pump on.  It dried out and everything seemed fine.  But now, my
cruise ain't working.  The fuse for it is alright.  What could be the
problem and how would I go about the diagnosis for it?

And idle problem that is REALLY WEIRD.  The valve I have taken apart
and cleaned.  my car idle's alright sometimes but then occasionally
it'll hunt between 1000-1400.  NOW, get this one.  I can pull the electric
connection and plug it right back in and it will be fine for the time
being.  BUT, this is stanger yet, I pull fuse 12, the one that 
controls instrument cluster, ABS, etc. and when I push it back in, it GOES 
AWAY!!  What is up with this?!  THis is to weird for me.  Any ideas?  
Please help, I'm running out of em!  Thanks
Rob
