enter the front foot well areas through a gap between the body and the sealing surface of the drain hose.

Production Solution
Improved condensation drain hoses and improved installation process in production.
Service
1. Expose both condensation drain hoses and inspect for incorrect installation, kinks or
obstructions that could compromise proper removal of the condensation from the A/C
system water drain. Refer to ElsaWeb >> 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. An
incorrectly assembled condensation
drain hose is one where the locating
tab is pointing up as seen in Figure
1. The correct orientation for this
locating tab should be pointing
down.

locating tab pointing up.

When the snap ring is installed
upside down, it allows condensation
to leak out through a hole at the
bottom of the snap ring (Figure
2). The water can then migrate into
either of the front footwell carpeted
areas.
Figure 2. Hole in snap ring.
3. Should the snap ring have been incorrectly installed to the body of the vehicle, do not
repair the condensation drain hose assembly. Replace the hose using the repair
procedure in ElsaWeb >> Heating, Ventilation and Air Conditioning >> 87 Air Conditioning
>> Removal and Installation >> Condensation Water Drain Hose. Improper installation at
the factory may have damaged the snap feature (opposite the locating tab), thus creating
a poor seal to the body.
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).

4. If the locating tab on the new part is in the wrong position (pointing up), then use a small
set of needle nose pliers to gently pull the snap ring 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 A/C system water drain. 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 A/C system water drain. Ensure that when installed
there is no kink or twist in the hose. If necessary, install a tie wrap at the A/C system
water drain end of the hose if a more secure connection is required.
9. Repeat for the other side.
