I have a 2002 C5 SX 2.2 which has done just over 43000 miles. This morning, after not moving the car for 3 days, I found that I have no air blower. On startup the LCD display shows the fan at its previous setting but within 30 seconds the display shows as though I have turned the fan off. I cannot alter this usingeither the Auto button or by manually pressing the fan switch. After startup I can press the fan switch and it shows on the display as speeding up but there is no air flow. I can adjust both sides of the climate control and can feel te temperature differance, I can also adjust the direction of airflow (screen, feet etc). The aircon button does not work nor does the windscreen clear. Any help would be gratefully appreciated. I have checked 3 fuses, 2 in glove box and one in engine bay. Thanks Rob
