The engine fans on my Amica are kicking in far too much, they come on as soon as I turn my engine on, even if the engine is cold. As a result of this my cars fuel consumption is getting ridiculous. I have taken my car into the Hyundai garage several times with this problem, and they've tried re-******* the air-con and replacing a relay, but these have only ever been a temporary fix (lasting 1-2 months). The last time my car went into their garage they insisted that they could not find a problem, is there anything we could try replacing to fix this problem?
