SERVICE INFORMATION
Some air conditioning units may exhibit white flakes blowing from the vents for a short time when the air conditioning is first turned on. The flakes are 1
mm or less in diameter and fall on interior surfaces like a light snow. This incident can be resolved by replacing the evaporator with an improved unit
according to the procedure below.
SERVICE PROCEDURE
Use the appropriate Service Manual instructions to replace the evaporator with the countermeasure unit listed on the following page (there is no new part
number -- check for the proper date stamp indicated in the Parts Information section). When installing the new evaporator into the vehicle, make sure
that the evaporator case drain tube is correctly aligned to the drain hose and that there are no obstructions.
NOTE:
To minimize the flakes remaining in the heater and air conditioning system, vacuum or blow out with compressed air any visible flakes in the heater
assembly before reinstalling the new evaporator assembly. Warm soapy water may be used to clean the inside of the evaporator case, heater case, and
all ductwork.
