noticed a while back that the AC fan is not coming on when I switch on the ac. as far as i know the fan should come on whenever the AC is on, regardless of the temperature (i usually set it to 16 or LO)?

I think it may be an issue with the engine bay fusebox as when i connected the earth from the AC clutch to the FAN the fan is starting. From nanocom I can see that there are some related errors. Any ideas before i remove the fusebox? :

You dont know far enough :) ... actually it's not the best setup by LR cos for aircon it should work more that it was designed to based on outside temperature(from 28*C or above), the inside setting has nothing to do with it hence i hacked it to kick in every time the A/C is on otherwise the pressure in the system is always at the upper limit when it's let's say 26*C outside and it kills the compressor in time

though those a/c related open load fault codes can be due to bad contact or "tired" relays... the ECU monitors the relay's coils
