Cherokee, Wagoneer, and Truck Air Con­
ditioner Operation
For maximum efficiency follow these instructions:
Before Starting Engine:
1. Close air vent, 1f open.
2. Open side vent windows to allow warm air to escape from
vehicle.
After Starting Engine:
1. Put the FAN Control Knob in either the HI or the PC (pre­
cool position) to pre-cool the evaporator. The FAN Con­
trol should not be kept in the PC position for more than
15 to 30 seconds before switching to the HI position. The
purpose of the pre-cool feature is to permit quick cooling
in the hottest weather conditions by preventing entry of
warm air into the vehicle until the evaporator has cooled
2. Put the TEMP Control Knob in the MAX position
3. When most of the hot air has escaped from the vehicle,
close vent windows.
4. Ad Just the four air outlet louvers to obtain desired
airflow distribution. Airflow can be adjusted for quick
delivery to a specific spot or for gentle diffusion of air
throughout the vehicle
5. When the interior of the vehicle has cooled down to the
desired temperature, the TEMP knob may be rotated to
decrease cooling. Turning the knob counterclockwise will
decrease cooling.
NOTE: It may be necessary for you to experiment with the
TEMP knob to determine the settings best suited to var,ous
driving conditions.
