206 - fan not cutting in?

[Harlequin]

heya , my friends car has a problem - the fan isn't coming on!

its a 56 reg pug 206 , 1.4 petrol. she says the thermo sensor has been changed. any idea`s?

Some more information about driving conditions might help. My fan hasn't come on for ages, but then I'm never stuck in traffic.

pressing the aircon buttons doesn't start the fan spiunning (which it does on my synergie) - maybe a switch or relay?

Check the fan to make sure it turns freely and is not seized. A seized fan isn't unusual on a 206.

Had a similar problem on my old 206 HDi, except the air con did spin up the fans. Took the front panels off to find the fan relays themselves were fine, but some of the wires were completely corroded to the point where they had become tubes of copper oxide. Fixed up the wiring to the relays and it clicked on fine, so that might be something to consider.

thank you all - yes the fan did turn , and replacing the relay fixed it all!

thank you all for the davice

Glad you got sorted and thanks for letting us know what the problem was. This information could be of use to someone else.
