Heated/Cooled Accessories - Vented Seats - Operation

VENTED SEATS

The vented seat assemblies are located internally to both front seats. The driver and front passenger vented seats are turned on and off by two separate switches located in the U-Connect Touch(TM) screen module. The vented seats will only operate when the engine is running, and will always stay off unless a vented seat switch is pressed. The vented seats are controlled by the Heated Seat Module (HSM), also know as the comfort seat wheel module. The HSM provides variable analog voltages that drive two 12 volt Direct Current (DC) motors. One motor is located in the seat back and the other motor is mounted to the seat bottom pan. Each press of a vented seat switch will cause the vented seat fan to change speeds from off to HI, HI to LO and LO to off. Both vented seats operate separately from each other and will not operate at the same time as the heated seats.

The vented seat system is diagnosed using a scan tool Testing and Inspection.
