Hi guys!
I ned Your help, I am not sure 100% what could resolve my problem.
Firstly the parameters of my car:
Peugeot 407 sedan
2.0i RFJ (EW10A)
2006
About the issue:
The cooling fan does not kick in at low speed at all. The high speed operates as expected.
I checked the car with pp2000, no fault codes.
I tried to test if I can turn on the low speed with the pp2000, but without any success. However during the highs peed test the cooling fan kicks in as expected.
When I turn on the A/C the pressure switch clicks and the cooling fan start operating.
I checked also the measured engine temperature and the cooling fan speed command field.
When the A/C is on, the cooling fan speed command value is about 50-60%.
When the A/C is off and the engine coolant temperature is above 98°C the cooling fan speed command field in the pp2000 shows 0%, and the low speed does not kick in
When the engine coolant temp reaches 105-108°C, the high speed fan kicks in and keep operating for about 10-20 sec.
I also checked in the ServiceBox when should kick in the low and the high speed stage of the cooling fan:
low speed at 98°C
high speed at 105°C
I checked the connectors around the cooling fan. the connectors and the relay seemed to be OK, no corrosion at all.
The wiring diagram is attached here:
I assume the fuse Nr. F1 and MF01 are fine as well as the relay, because the cooling fan kicks in at high speed and when the A/C switched on.
Other guys say the cooling fan itself is the fault and it should be replaced.
I am thinking about accepting thier suggestion and replacing the cooling fan unit could resolve the issue.
But i am not 100% confident about it and that is why I really need Your help.
A new cooling fan is not a cheap thing, so I do not want to find myself in a situation where I buy a new cooling fan for 300Euro and replacing it does not fix the issue.
I would really appriciate if You could help me with your knowledge and experience.
Thank You for reading this post and for making effort to help me out
Best regards,
Matyas
