Replace radiator fan control module

[alloy]

Radiator does not come on when needed and engine may overheat. Performed workshop manual test by replacing thermostat by 100Ω resistor, in which case fan does come on, so fans are ok.

Get a range of 10-100Ω resistors to find the resistance needed to simulate normal heat, so that I know the module is actually kicking in at normal use.

Or find a very low resistance potentiometer instead, although these all seem to go into the kΩs very fast.

I had to take out the battery, the air filter box, and the air intake:

Then I was able to easily access the module:

And finally take it out:

After replacing the module, I turned on the AC on max and the fans came on! \o/

I still have to test it on the road when the engine actually becomes hot, but I have good faith.
