Check the heater/evaporator case for debris. Remove any debris present through the resistor block opening. If the debris is imbedded into the
evaporator core face and cannot be removed, the core will have to be removed from the vehicle and cleaned off the car. If a large amount of debris
is present in the heater/evaporator case, the air inlet screen will require sealing around the windshield wiper post holes and fender edges as shown
in Figure 1.

7.
Set the mode selector lever to vent, blower switch to low speed and temperature lever to full cold.

Open all windows and doors and exit the vehicle.
CAUTION:
DO NOT ENTER THE VEHICLE UNTIL CLEANING PROCEDURE IS COMPLETED TO AVOID EXPOSURE TO DISINFECTANT.
9.
Place drain pan with at least a two quart capacity below the heater/evaporator drain to catch the disinfectant and rinse water runoff.
