The sensors in the radiator have one blue/white, live, cable, and one brown - earth via relay, fuse etc.
I have a problem that my fans do not start although they run OK if I connect the live cable to earth.
The manual on CD is of such low quality that the wiring diagram and the trouble shooting scheme are unusable.
Could someone help, please?
I have a 155 2,5 TD, but suppose the basic principles are the same for all 155s.
