TSIB
IntroductionA musty odor may be emitted from the air conditioning system of some vehicles which are
usually operated in areas with high temperature and humidity. It is most noticeable when
the air conditioner is first turned ªONº after the vehicle has bee\
n parked for several hours.
The odor could result from one or more of the following conditions:
1. Blockage of the evaporator housing drain pipe, resulting in the build up of cond\
ensation.
2. Microbial growth in the evaporator, arising from dampness in the evaporator housing
where the cooling air flow is dehumidified.
To address excessive air conditioning evaporator odor, check the evaporator housing drain
pipe for blockage. If no problems are found, the evaporator and housing\
should be cleaned
and disinfected using the general procedure given on page 2, and the model \
specific
procedure on the pages indicated in the Table of Contents at the bottom of this page.
Affected While this procedure may be used on any Lexus vehicle, this bulletin giv\
es details
Vehicles specifically for the '92±'96 ES 300, all GS 300, '93±'94 LS 400, all SC 300/400 and the\
