A/C Control Head Assembly (Controller)

The controller consists of three electronic printed circuit boards housed in a plastic box attached to the instrument panel. Fourteen soft touch key pad switches on the flat surface membrane faceplate are used to address the MPU. Eleven of these low current switches each contain a yellow light emitting diode (LED) annunciator.
