P'UP (KB) AND TROOPER II (KT) BLOWER MOTOR WATER ENTRY
Water entering through the fresh air intake into the blower motor may damage the blower motor. A blower case guide can be installed to divert the water.
This Service Bulletin describes the installation procedure for the blower case guide.
For vehicles with air conditioning (factory-installed or AIMI air conditioning), a redesigned evaporator drain hose is also available to prevent water
build-up in the evaporator.
Install the blower case guide as follows:
Remove the blower motor and its cover.
Copy the template in Figure 1 (shown actual size) and cut a template from a piece of cardboard.
Position the template on the bottom left side of the blower case, over the air cooling hole as shown in Figure 1.
Trace the template hole outline onto the case with a pencil.
Using a file, enlarge the air cooling hole according to the outline markings.
Apply a thin bead of silicone sealant to the flange of the guide.
