Omega Electrical and Audio Help / Another radiator fan topic
« on: 26 June 2017, 19:32:24 »
I've searched the forum for 3 days before posting so I am positive this is a new one.
Skiping the radiator fan test, the 2.2 dti has a different layout in the relay box or I can't identify the test connector, one or the other.
So, measuring at the fan connector (car side) I have negative and 13.2V on both power wires, never in the same time. Exterior power wire on connector has power until 95 degrees (C), midle over 95. So we have power at the connector. Testing the fan directly with battery power shows that only one pin reacts to power, and that is the outside pin. With power on the midle (+) pin and negative pin the fan has no reaction. Again, on the outside pin it does go full power while connected to the battery.
So, power on the connector, at least one stage of the fan working. Plug in the connector, nothing happends, at any temperature. The only fan kicking in over 95 C is the AC one in the front.
Changed all the relays with ones from a working car. Measured everything that came to my mind. Right now I am out of ideeas.
So. What do I do next?
