Control or system failure
You must know the importance of the heater/defroster always being available for keeping the windshield clear of condensation, and that a vehicle has this minor defect when the heater/defroster system operates incorrectly.


    • Turn on heater/defroster fan for all directional controls/ positions and ensure the system operates correctly in all positions.
    • When applicable, ensure the defroster keeps the windshield clear.
