- ignition key at STOP;
- set temp (1) knob at MAXIMUM HEAT;
- set fan (2) speed knob at 0;
- set placement (3) knob to FACE (furthest anti-clockwise);
- turn ignition to MAR (don't start engine;
- operate fan (2) speed knob in following sequence:
AUTO-0-AUTO-0 (allowing AUTO time to turn on fans)
- move ignition back to STOP

If this doesn't work you've switched from 0-AUTO etc too quickly. The fans MUST turn on before you return to 0 each time.

To return to auto setting just repeat the above method.
