radiator fan

Hello, after starting the fan motor, it runs at full frequency. No reaction when the effect is turned on or occurs. Do you have any ideas L322 2007 3.6 TDV8

Jeśli przełącznik ciśnienia czynnika chłodniczego zostanie wykryty jako uszkodzony, wentylator będzie pracował z pełną prędkością, ponieważ nie można wykryć ciśnienia. Odłącz przełącznik i powinien zatrzymać wentylator.

I hope the translator worked OK!

the car has had its air conditioning serviced, so there shouldn't be too much pressure.

It's on the AC pipe on the (EU) passenger side near the fuel injectors. It's possible the system has been overcharged, this would also cause the problem, as would a faulty sensor indicating too much pressure.

The air conditioning pressure sensor is operational and shows 7 Bar in the system. No ideas. Should the replaced fan be attributed to the computer?

Do you mean the electric or the viscous coupled fan? both will work without programming but the diagnosis is different.

Hello, I'm talking about the electric AC fan, after starting the car it works at full power regardless of whether the air conditioning is on or not. After connecting the computer, it does not report any errors. It was changed because the old one didn't work at all.

You didn't mention that previously!
The thin black-green wire is the control wire, disconnect that and see what happens - if no change it could be a bad internal connection on the fan or a faulty fan, can you try plugging in a known good one?, the fan is controlled by the engine control module, not the climate control module, so it may not be linked to refrigerant, it may be a coolant temperature sensor problem.

I disconnected the cable and then the fan stops working, and the error appears as a break in the fan control. The engine temperature sensor shows that it is OK, there are no errors related to the air conditioning. The fan is the second one because the first one didn't work so I'm out of ideas.
