ISSUE:
Condensation may drip from the floor duct when the A/C is operating. This occurs because the location of the evaporator core inside the housing allows
high velocity air to carry water droplets from the core face beyond the sump area in the housing.
ACTION:
Replace the evaporator core and housing assembly with a new assembly which has a relocated evaporator core that allows the condensate to drain into
the sump area of the housing rather than into the passenger compartment. Refer to the following procedure for service details.
NOTE:
USE PROCEDURE # 1 FOR 1994 MODELS ONLY AND USE PROCEDURE # 2 FOR 1989-93 MODELS.
CAUTION:
