Caddy AC programmer

[Scott=John=Mockry%Mktg%TM@banyan2.BV.TEK.COM]

Hello,

A friend who works at General Motors gave me the electric motor off  a Caddy AC programmer
and it worked great as a replacement for the one in my 86 5000CS T. I had to take the plastic
arm off my motor and put it on the caddy motor. 

My friend also recommended putting a 680K ohm resistor across the center to ground legs on the
motor potentiometer that is used to sense the arm position. Apparently Caddilac had a service
bulletin recommending the procedure. Sometimes the potentiometer wiper contact gets oxidized
and causes an open circuit going to the op amp used to make the motor move when a "new" 
temperature is chosen.
