[87#184saleen]

i have a 2004 cayenne s im having problems with my fan it doesnt turn on it runs cool like 180 on the freeway but when i start sitting on traffic it starts to heat up and the main fan doesnt turn on i just chage my water pump thermostat and water temp sensor i wonder what it is fuse relay or what if anyone could help o by the way i upgraded the cooling pipes a while back

My first thought would be to check the wiring and/or the temp sensor to make sure it is the correct one if it isn't working. The fans are fused also, check your manual as mine is a '06 so it is most likely a different fuse.

Yeah checked for fuses but cant find none related to the fans I don't know in what temp does the fan turn on

Do the fans operate at any speed when the A/C is operating??

[87#184saleen]

yes wvicary they do only the small one when the ac is on

the temp gos over 200f and i dont hear any fan on

[wvicary]

There is a fan control module located on the fan housing. Are there any fault codes?

i havent checked if theres a code i need to take to a place were they have a Durametric scanner do they have a part number or i have to buy the fan also
