Rear Climate Control - Overview

The rear climate control system operation is determined by the settings on the Touchscreen, front climate control panel selection or from the RHVAC control panel selection. The rear climate control components are hard wired to the FCIM. Air is cooled and dehumidified by the rear A/C evaporator core only if the front (main) climate control system is operating in a mode that requires A/C compressor operation. The rear climate control system air can be heated at any time.
