ISSUE:
Water droplets in the air conditioning system may become airborne. Condensation forms into droplets which would follow the airstream as it flows
through the system and out through the floor ducts into the passenger compartment. This occurs because there is a build-up of localized high velocity air
in the evaporator case which moves water droplets toward the floor ducts.
ACTION:
Rework the evaporator case and install a baffle to prevent the build-up of high velocity air. Refer to the following procedure for modification and service
details.
BAFFLE INSTALLATION
1.
Using aluminum plate stock about 1/16" (1.6) thick, make the baffle shown in Figure 1.
a.
The bend between the 5 1/4" (133mm) and the 1" (25.4mm) sides of the baffle is about 90 degree
b.
The two 3/16" (4.8mm) diameter holes in the 1" (25.4mm) side of the baffle are provided for attaching the part to the evaporator case.
2.
Squeeze the sides of the glove compartment assembly toward the center of the compartment to gain access to the evaporator case. This will free
the attaching tabs at the upper rear corners of the assembly and allow it to be hung free.
3.
Working through the glove compartment opening, cut a 1/16" (1.6mm) wide by 2 1/2" long slot in the evaporator case.
