Hello,

I have a problem with my pusher fan on e46 328ci 1999.When I turn the AC on the pusher fan kiks on full speed even when the engine is cold in the morning.
I have changed the coolant sensor and re-charged AC gas and checked all fuses and they seems ok.
Have anyone had this problem and what else i can check is there any speed relays etc that regulates the fan speed.

Thank you for your help.

You see that module built into the shroud of the fan?



That is a built-in final stage (resistor/switch) and the signal to run is provided by the DME. My guess is that it is not functioning correctly.
