Ford 7840

On a small number of vehicles, the ground connection for the heating, ventilation and air conditioning (HVAC) blower motor may not have been secured properly. As a result, the defroster could stop working, and you may not be able to defog or defrost the windshield.

Ford 7840 problem arrived as it would not go into gear and then would not stop lift arm from lifting. Both problems seemed to have been fixed with a recalibration. However once put into reverse the fault 27 arose againand lift arm calibration undone it seemed. After checking for bare wires , top up oil and other simple checks, the tractor drives again , lifts up and down but does still seem to not let off pressure at the top end of the lift arm. Also fault 12 appears. Any insight in where to start to get theses issues fixed would be greatly appreciated , thanks
