AC programmer ?s

What the ?

OK so I get up at the crack of dawn, perfect weather in CT this weekend and
I drop a new set of lifters in the girlfriends '87 5kq.  All goes fine. 
The car is now silent once again.

While I'm under the hood I put in the 80amp fusable link for the fan.  I
had disconnected the battery for this.  So I hook the battery up and hear
the flaps under the dash do their thing and the cd pops out of the Kenwood.
 

Fire up the car and now it is behaving as if the programmer is shot. 
Everything comes out the defrost vents whether it is AC or not.   Turn the
cc to OFF, restart the car and it is back to AC.

Now you ask, was it bad before.  Well I don't drive it.  It has been
sitting a month while waiting for her to get the title mailed to her after
paying the car off, and then we got busy and it has been sitting.  

So maybe the programmer was dead but I don't think so. No I'm sure
everything worked fine before I undid the battery.  Is there a procedure
for reseting the programmer?  Something buried deep in Bentley I can't
find?

I know that vacuum leaks can also switch the thing to defrost only but
again I think everything worked fine when we parked it and I only undid the
vac. line to the cruise when I did the lifters.

Ideas?

Thanks

Neil
