Does anyone know of a good source for a rebuilt programmer?  I know
about Mountain Automotive, but they're pricey, and Blau only has new

What's wrong with yours? Usual problem is oil in the solenoids. These can
be replaced - the solenoids are from some GM cars (see your local
junkyard), and solder in.

Quick diagnosis - remove programmer, remove cover (pay attention to
position of fragile actuator arm), shake PC board. Solenoids that rattle
are OK, solenoids that are quiet are oil soaked and need to be replaced.
Change the little filter and the hoses, too. Use parts from the $10 donor
box you bought from junk yard (mid 90's GM big cars - Olds, Buick, many
Caddys use same climate control system. Mounting tabs, brackets, etc. are
different, but components are the same.)
