Hello,
It sounds like you might have a faulty radiator cooling fan control module.
As the module is basically telling the ECU that the engine is too hot and the fan keeps running.
This was a common issue among these lancers. There was even a recall to change those modules out.
This was a common issue with the Lancers that were in a humid climate, as moisture would make the circuit board on the module for bad.
The fan control module is located right behind the fan (see diagram).
There is a quick way to test the module. I have attached the testing instructions.

I have attached diagrams for your reference.
Please let me know of any questions.
Thank you.
