HVAC Control Assembly

With the Ignition Switch in "RUN," voltage is applied through the CLSTR Fuse and CKT 541 to the HVAC Control Assembly. The voltage from CKT 733 is varied from Battery to approximately 1.5 volts by the Temperature Control Potentiometer. The Control Assembly provides ground paths for the Solenoid Box through CKT 150 and the control switches.
