Evaporator Case: Customer Interest
A/C - Evaporator Drain Tube Water Leaks to Interior
No: TSB-02-55-006
DATE: August, 2002
MODEL
1999-2002 Galant
SUBJECT:
A/C WATER LEAKAGE AT EVAPORATOR DRAIN TUBE OPENING
PURPOSE
Customers may complain of A/C water leakage onto the driver side floor. The leakage may be more noticeable after the air conditioner or front defogger
has been operated.
This condition may be caused by drain tube blockage, or the heater unit not being properly sealed to the bulkhead. The bulkhead silencer pad may be
positioned between the evaporator foam pad and the firewall, causing an improper seal. This could cause the evaporator drain tube foam to become
deformed and allow water to drain onto the floor.
To eliminate this condition, first check for drain tube blockage. If no blockage is found, install a new evaporator foam pad as described in this bulletin.
Also, inspect the heater assembly for cracks or other damage that could cause leakage. If cracks or other damage are observed, replace the heater
assembly.
