OK the wife's VT comes up with 2 codes. 12 - System Pass (OK) 92 - Low Speed Radiator fan response signal The problem is the thermo fan switches on at startup sometimes (engine cold and A/C off) and stays on. If you turn the car off and on it's all good though. It's a V6, had a new radiator, thermostat and flush 10 mths ago and runs fine other than that. Any ideas?
