I have an Omega 3 litre V6 model which has just had the air conditioning re-gassed everything fine however it appears that one of the two auxiliary electric fans (front nearside) in front of the A/C radiator is not coming on. Are both the fans meant to come on simultaneously as only one appears to be working? All fuses appear to be OK. The fan on the right side comes on immediately but nothing from the left one. The non operating fan does spin freely and is not seized. What's the best way to isolate the problem to the fan or its controller? I assume they are both meant to come on together. I should be grateful for anyone with experience of this. Mark
