1996-97 I30, MIL "ON" OR POOR DRIVEABILITY DUE TO A/C EVAPORATOR CONDENSATION LEAKING ONTO ECM
APPLIED VEHICLE:
All 1996-97 I30 (CA32)
SERVICE INFORMATION
If a 1996-97 130 exhibits a MIL "ON" and/or poor driveability such as engine hesitation or no starting, the cause may be A/C evaporator condensation
leaking onto the engine control module (ECM). A/C condensation can accumulate and leak onto the ECM if the A/C evaporator drain tube becomes
blocked by debris such as leaves, insect nests, etc. Such debris can enter the A/C air intake duct through openings in the cowl top cover and around the
windshield wiper pivot shafts.
To prevent debris from entering the A/C system, a new cowl top cover and wiper pivot shaft seals are now available. The new cowl top cover has foam
seals (mounted on its underside) that keep debris away from the A/C air intake duct. The new wiper pivot shaft seals have additional material ("flaps")
that prevent debris from entering the cowl top cover openings around the wiper pivot shafts.

CLAIMS INFORMATION
When applicable, standard claims coding applies.
Service Procedure
1.
Check for wetness and/or mildew on the passenger side carpeting around the ECM area and check the ECM for signs of water damage (see Figure
1 for ECM location).
A.
If the carpeting is dry and mildew free around the area of the ECM and there are no signs of water damage (wetness, water spots, corrosion,
etc.) to the ECM, use the service manual to diagnose the incident DTCs.
B.
If the carpeting is wet and/or mildew is present around the ECM and the ECM has signs of water damage (wetness, water spots, corrosion,
etc.), proceed with step 2.
2.
Replace the water damaged ECM with the correct service part number (see Figure 1).
