A/C Drain Tube - Water Leak In Passenger Compartment
NO: 24-16-94
GROUP: Heater & A/C
DATE: Nov. 4, 1994
SUBJECT:
Water Leak in Passenger Compartment Under Instrument Panel - A/C Drain
MODELS:
1995 (PL) Neon
SYMPTOM/CONDITION:
Water leak on passenger floor area on left hand turns. This condition is most likely to occur when the A/C system has been in operation.
DIAGNOSIS:
1.
Raise vehicle on a hoist to allow access to the A/C condensate drain tube.
2.
Note the orientation of the A/C condensate drain tube. The drain nipple should be pointing towards the ground at the 5 o'clock position. Remove
the drain tube and check for debris or restrictions. If the drain tube is clean, proceed to the repair procedure.
3.
If the drain tube is restricted, clear the opening and remove any debris and install the drain tube back on the vehicle with the correct orientation.
Further diagnosis will now be necessary to determine the cause for water entry into the vehicle and will not be covered in this bulletin.
REPAIR PROCEDURE:
This bulletin involves removing a blockage in the evaporator housing to A/C condensate drain tube nipple.
1.
Insert a long narrow tool, with a hook on the forward insertion end, slowly into the A/C evaporator drain nipple. The tool can be made out of a
wire type coat hanger, with a hook fabricated on one end not to exceed the diameter of the drain tube. The hook will be used to remove styrofoam
liner material.
2.
Force the tool carefully through the styrofoam liner that is inside the evaporator housing until the liner is punctured. Usually water will be
discharged from the drain nipple
NOTE:
WHEN FORCING THE TOOL INTO THE EVAPORATOR HOUSING, USE CAUTION SO AS NOT TO DAMAGE THE EVAPORATOR.
3.
Remove the tool while trying to remove all or any of the liner material causing the blockage. Insert and remove the tool repeatedly to remove as
much of the material as possible.
4.
Install the drain tube back on the vehicle with the correct orientation.

Reimbursable within the provisions of the warranty.
