Moisture in the driver or front passenger foot well.
Technical Background
The drain hoses were incorrectly assembled by the supplier, thus allowing condensation from the evaporator to
enter the front foot well areas through a gap between the body and the sealing surface of the drain hose.
Production Solution
Optimized evaporator drain hoses.

Technical Service Bulletin
Service
1. Uninstall both drains hoses at the center console as indicated by the repair manual in
chapter Heating, Ventilation and Air Conditioning >> 87 Air Conditioning >> Removal and
Installation >> Condensation Water Drain Hose.
2. Inspect both drain hoses to identify if
they are incorrectly assembled with
the locating tab pointing up as seen in
Figure 1. The correct orientation for
this locating tab should be pointing
down.
Figure 1. Incorrectly assembled drain hose, with
locating tab pointing up.
When the snap ring is installed
upside down, it allows water to leak
out through a hole at the bottom of
the snap ring (Figure 2). The water
can then soak into either of the front
footwell carpeted areas.
Figure 2. Hole in snap ring.
3. Install new service parts; do not repair original drain hoses. Improper installation at the
factory may have damaged the snap feature (opposite the locating tab), thus creating a
poor seal to the body.

Technical Service Bulletin
Service parts have been checked, but
it is still possible to receive
unchecked parts. Corrected parts will
be marked in white on the locating
tab. This tab must be pointing down
(Figure 3).
Figure 3. White mark on locating tab.
4. If the locating tab on the new part is in the wrong position (pointing up), then use a small
set of needlenose pliers to gently pull the snap wring out of the rubber hose and align it in
the correct position (pointing down). Dipping the end of the hose in soapy water may make
the process easier.
5. Reinstall the snap ring in the correct
position indicated by Figure 4.
Figure 4. Snap ring installed in the correct position.
6. Connect the hose to the body before connecting it to the HVAC unit. Insert the locating tab
(bottom of the hose) into the body hole and press the top portion of the snap ring into
place.
There should be an audible click to indicate the hose has made a firm connection.
7. Inspect the seal by gently tugging on the hose to ensure it is completely seated.
8. Connect the top of the hose to the HVAC unit.
