If none of the fan settings work, then the motor has had it.

Easy to fit, it's right under the steering column.

Ideally you should buy a new motor, aftermarket should be fine or OEM if your wallet allows.

the only other possibility is a burnt out resistor pack.

If it was a fuse, something else in the car won't work as there are no single fuses.

It could be as simple as a blown fuse or other problems...you would have to test for power and a good ground at the fan motor and go from there. Or run a jumper wire from the battery positive terminal to the motor positive wire lead and see if the motor works to test it . There is a resistor by the fan motor which also controls the fan speeds in conjunction with the heater control fan switch...any of those items could be bad...motor , resistor or switch... or the ground wiring is bad.

Hi here again we have a worn out old car with problems as Citroen never made a car to last beyond ten years the problem is part of the make.

so yes it could be a heater blower that needs to be replaced but as we have seen earlier with yet another one a blower heater motor from a scrap yard is just as likely to be faulty.

there is only one real answer a newer car sunshine.

You of course have an instantaneous short to floor. you will ought to discover and fasten the fast to repair this project. First, confirm the blower motor via using working a jumper twine out of your effective battery terminal to the flexibility terminal, if this would not energize the fan, the motor is burnt out. you will ought to song backwards from the fan motor to the fuse panel to discover the source of the fast. talk over with the link under for info on troubleshooting an electric powered short:
