Fan Module UPGRADE(W203 radiator electric fan)

Read many suffered with low reliability and high cost to replace the whole fan when module has failed....( think some other models like ML and S-class also have this same setup)

The module is not sold separately.

The motor seems(I may be wrong) to be running on AC(alternating current) and require the module to run(I tried connecting DC to two of the three thick wire to the motor. It doesn't work regardless of permutation available) > (the fan blade moved about 30deg and stopped when connected to DC). There are 4 cables from the motor(3 single core thick wires(should be for supply) and one with several colored thin wires inside)

I wonder if fan modules from the older or other models (with module not integrated into the fan assembly) can be connected to replace this module?(like those on SLK with module not attached to the fan housing).

(I intend to convert this fan into a, I don't need to worry about sensing(sensor signal), if any from fan motor back to module or ECU)

Thanks in advance.
