Press up or down on the blower motor control to select the blower motor speed.
Note:
Lights on the control illuminate to indicate the blower motor speed.
Note:
When you switch the blower motor off the air conditioning turns off and the windows could fog up.
Note:
In certain conditions, for example, when the vehicle is travelling at a higher speed, the blower motor fan may change speed due to the air pressure built up near the windshield cowl area. This concentrated air is forced through the A/C vents into the cabin resulting in a change of blower speed. This is normal operation.
