Subject: Correcting Complaint of Failed Fan Control/Fan Resistor
Application: Certain 1992-1995 9000 Models
On certain cars the fan control (ACC) or fan resistor (manual A/C) can overload and break. This is caused by a ventilation fan that is too sluggish. A
sluggish fan consumes more current in maintaining the speed set by the ACC control module or fan control. This higher current draw may be enough to
cause overloading of the fan control or fan resistor.
Manual A/C system: To rectify the fault, change the fan resistor and check the fan using the method described below. If the fault is due to excessive
draw, the fan should also be changed.
ACC System: To cure a fault, a new fan control with automatic overloading cut-out has been developed. The overloading cut-out turns off the ventilation
fan under certain driving conditions. The ventilation fan should also be checked by the method described below. If current draw is higher than the
permissible limits, the fan should be changed.
Modified fans consume less current than fans of earlier types, but have the same part numbers. Stock of earlier design fan have been scrapped.
