Normal Operation
The climate controlled seat module (CCSM), based on the setting of the climate controlled seat switch, outputs voltage on circuit 1256 (WH/YE) to illuminate the COOL icon on the climate controlled seat switch or circuit 1255 (WH/RD) to illuminate the HEAT icon on the climate controlled seat switch.

Possible Causes
One or more climate controlled seat switch LEDs inoperative can be caused by:
- wiring, terminals, or connectors.
- climate controlled seat switch.
- CCSM.
