AIR CONDITIONING

DESCRIPTION AND OPERATION

82-25

Blower
The blower controls the volume of air being supplied to the distribution outlets. The blower is an open hub, centrifugal 
fan powered by an electric motor. A dust filter is installed over the fan inlet. The blower switch on the control panel 
and the resistor pack control the operation of the blower, which can be selected to run at one of four speeds.

Resistor pack
The resistor pack supplies reduced voltages to the blower motor for blower speeds 1, 2 and 3. For blower speed 4, 
the resistor pack is bypassed and battery voltage drives the motor at full speed. The pack is installed in the air outlet 
from the blower fan, so that any heat generated is dissipated by the air flow.

Distribution system

Air ducts
Ducts connected to the rear evaporator/blower motor assembly distribute air to five vent assemblies in the roof.

Vent assemblies
The vent assemblies allow occupants to control the flow and direction of air. Each vent assembly incorporates a 
thumbwheel to regulate flow and moveable vanes to control direction.

Rear control system
The control system operates the blower to control the operation of the rear A/C. The control system consists of two 
control switches and a rear blower relay.

Control switches
A rear A/C switch and a blower speed switch are installed on a control panel in the roof lining. The A/C switch is a 
latching pushswitch with an amber indicator lamp which illuminates when rear A/C is selected on. The blower speed 
switch is a slide switch with a positive detent at each of four speed positions (there is no off position).

Rear blower relay
The rear blower relay controls the electrical supply to the blower.
