SERVICE INFORMATION

To improve the time to clear heavy condensation or frost from the inner or outer surfaces of the windshield during periods of high humidity/low temperature ambient conditions, the owner should be aware of the owner's manual operating instructions regarding the use of the ventilation, heater and air conditioning system. It is particularly important that the air-source select lever usage is fully explained, since improper use of this lever can cause a complaint condition.

In the event of the complaint condition existing with the correct usage of the heater controls, the right and left hand defrost ducts (nozzles) should be replaced using the 1987 components following the Shop Manual procedures:
