Fan Speed Increase/Decrease
1995 Oldsmobile Aurora V8-4.0L VIN CSECTION Fan Speed Increase/Decrease
The Buick fan speed increase/decrease switch is used to manually change fan speed. Pressing the increase end of the fan speed switch once, increases the fan speed one level. Holding the increase end of the switch, increases the fan speed until the switch is released or maximum fan speed is reached. Pressing the decrease end of the switch, decreases fan speed in the same manner.
The Oldsmobile fan speed control knob is a rotary switch without mechanical stops. In the manual fan speed mode there are nine speed settings, which are selected by rotating the knob clockwise or counterclockwise. The corresponding LED will be illuminated in relationship to the blower speed. By pressing the fan speed control knob, the fan will operate the "AUTO" mode where the programmer selects the appropriate blower speed.
If the system is operating under "AUTO" fan speed control, moving the fan speed switch causes "AUTO" fan speed control to stop and manual fan speed control to begin. Fan speed remains constant, unless the increase/decrease switch is rotated again.
With the system in "OFF" mode, pressing either end of the fan speed switch causes the system to turn on in the "AUTO" mode with "AUTO" fan speed control.
