volvo xc 90 d5 radiator fan not working
 

Hi I have a march 2006 xc90 d5 miles 184000 miles.I have had car for 16 months and have done 14000 miles since I have owned this car.
My problem is my rad fan not working.
I have tried 3 rad fans the one on now was tested and worked fine on a frainds xc90.
When I put my diagnostic in .icarsoft it reports control mod not working.
Now I now it works as tested on a different car,I have tested voltage and getting 12 volt plus earth fine.Pink wire is 7.2 volt but does not change.
temp gauge working fine.
Fan not coming on with ac either..
Thinking back I have never heard my fan kick in and on the odd occasion IE when I climb long steep hill engine service light comes on orange and goes out once I get on flat.
Temp gauge once warmed up sits just past middle never gone higher.
Anybody can help before I put a universal fan on and never have ac working.:confused:Many Thanks..
