Default Fan problems driving me crazy :(

Hi everybody!
Another problem on my car,the fan doesnt come on (both),i tried with the key "ON" position and A/C turned on,and the fan doesnt work,i tried with engine running and when the temp reaches ,the fan doenst come on,i disconnect the antifreeze temp sensor and it turns on (both),i replaced the sensor for a new one,and the same thing .
I checked for a grounded wire,and all the harness is fine,no grounded wires,what else could it be????
the wires are pluged right on the ECM.
Also i checked the fuses.

Any suggestion??
