Hello, i have this trouble with my 04 XC70, the cooling fan stays on even in a cold start, it starts at full speed about 3 or 5 secs after start the engine.
I think this could be for:
1.- Fan control module and ECU problem.
2.- Faulty wiring.
There's no error reported on the car computer, what could you advice?
Is there a way to test the wiring? voltage readings?
As far i know this fan has 3 speeds, how can I test if the ecu is commanding the fan to stay on at full speed?
Thanks in advance!
