Hi,

First, this vehicle isn't offered in the US, so my technical information is very limited. However, I will try my best to help.

Since the fan motors are good and you replaced the ECT already, I need you to follow the wiring from the ECT to the control module. Also, follow it from the fan motor back to the control module. From what I've read, the wiring on these vehicles for the fan is very susceptible to damage.

Let me know if you find any issues. Also, confirm the connector at the ECT to make sure it isn't damaged and shorting when you connect it.

Here is a link you may find helpful:

Take care,
