Problem with the GMC Yukon 2005. DTC is P0480. When ignition is off the radiator electric cooling fans run continuously until the battery is run dead. When key inserted and turned to ON the fans turn off when weather is cold outside (~35 deg) and seem to run normal when engine is running. Where should I start looking?
have the same problem?
