Instructions for Internal Fan Adjustment

Model: Vauxhall Vectra Vectra C, MK 3 - Years 2002-2008
Part: Air conditioning

If adjusting the speed of the internal fan does not change the airflow, there may be an issue with either the speed controller or the fan itself. To access the internal ventilation system, remove the glove compartment on the passenger side: open the door and unscrew the three screws along the upper inner edge; then move on to the two screws underneath and remove the glove compartment after disconnecting the internal light bulb connector. At this point, you can access the rear of the centre tunnel and remove the speed controller: it is a plate located just below the motor; once removed, check its functionality by inserting a bulb into the connector that goes to the motor: the brightness should increase as the fan speed setting increases. If the result is positive, then the problem lies with the fan: remove the front cover and check if the rotation is free or slightly obstructed; in the latter case, lubricate the fan until it rotates freely.
