Freelander 1 Electric Fan behind LHS headlight, 2005 Td4 Auto.

An Electric Fan behind/below LHS headlight runs continuously even with key not turned on and engine cold, only pulling the fuze stops it (& boot barn door lock offline). Not sure if it AC related as it still operates normally.
Neither of the big electric fans on the radiator are running at the same time.
Also, just had the thermostat replaced at very expensive $ & a friend suggested maybe it sensor tripped caused by a vapor lock. Engine temp rises normally & sits at tad below middle

FYI update error correction,,
Turns out it is the Trans oil cooling thermo fan module,, activator or sensor must be fused in on position.
What is needed to fix this please?

FL1's in warm climates had an air blast fan fitted to the auto. We don't hear of many of them. It's covered in the rave disk. Link in my sig below.
