From another forum re. same fault .
CITROEN C5 AIR CON BLOWER MOTOR?
I HAVE AN 2003 C5 2.2HDI EXCLUSIVE WITH AUTO AIR CON. THE BLOWER WAS WORKING FINE ON AUTO SETTING, THEN SUDDENLY WENT OFF WITHOUT ANY WARNING WHILE STILL DISPLAYING AS ON. IS THIS LIKELY TO BE THE MOTOR OR AN ELECTRONIC ISSUE.
A new control module cured mine. No fan power at all was the fault. Price 58 +Vat.
99% chance its the fan control module it's located in the heater unit ,to gain access remove the shroud under the steering wheel the fan control module has 2 seperate plugs one with a thick red and black cable the other with a thick red and black cable and 2 thinner cables it is held in in place with 2 hexagon screws the top one is difficult to see without a torch it is very easy to remove, it can only be obtained from main dealers and costs about 58 quid inc vat just changed mine with same symptons and now works perfectly a very common problem on all french cars
