SEOCONTENT-START
Bulletin No.: PI1408E
Date: Oct-2017
Subject: Musty Odor from HVAC Vents on Startup
Models: 2013-2016 Cadillac
ATS
2014-2016 Cadillac CTS Sedan (VIN A)
Attention: This PI also applies to any of the above models that may be Export from North America vehicles.
This PI has been revised to add the 2016 Model Year. Please discard PI1408D.
Condition/Concern
Some customers may comment on a musty or mildew odor coming from the HVAC instrument panel air outlet vents on startup. The odor most likely will dissipate after 30-60 seconds of operation. The odor generally occurs after the vehicle has been parked for 2–6 hours with sun load with temperatures of 21°C (70°F) or higher.
This may be caused by condensation building up on the evaporator core, which does not evaporate by itself in humid conditions. The odor may be the result of microbial growth on the evaporator core being released into the air stream by the HVAC blower motor.
Recommendation/Instructions
Follow all the steps below to reduce the HVAC musty odor:
Install the latest HVAC Control Module calibration and enable After-blow
Refer to Tis2Web and SI Procedures for enabling after-blow.
For 2013 ATS’s built prior to VIN 1G6AH5RX0D0142531, refer to the latest version of PIC5730: Enabling After-blow.
Drain Tube Inspection
1. Verify that the plenum area is free of any debris.
2. Inspect the drain assembly for the presence of a white or light blue plastic drain tube using the latest version of PI1160. If the secondary tube is present, replace the drain hose assembly.
Apply Oxyvap Cleaning Agent
1. Place the passenger seat in the full rearward position.
2. Disable the SIR. Refer to SIR Disabling and Enabling in SI.
3. Remove the instrument panel compartment. Refer to Instrument Panel Compartment Replacement in SI.
4. Remove the front floor console extension panel – right side. Refer to Front Floor Console Extension Panel Replacement – Right Side in SI.
5. Remove the right front side door sill trim plate. Refer to Front Side Door Sill Trim Plate Replacement in SI.
6. Remove the floor front air outlet duct – right side. Refer to Floor Front Air Outlet Duct Replacement – Right Side in SI.
7. Remove the blower motor. Refer to Blower Motor Replacement in SI.
8. Pull back the carpet and roll it back towards the passenger seat.
9. On the lower HVAC case, scribe an “X” in the area shown.
10. Drill a 3 mm (1/8”) pilot hole in the middle of the “X.”
11. Drill a 19 mm (3/4″) hole in the center of the air duct between the blower motor and the air distribution box. The use of a Uni-bit style bit works well. The use of a spade bit will produce excessive plastic chips and may cause the drain to get plugged.
Note: Use a vacuum to collect as many of the plastic chips inside and outside the HVAC case as possible. The blower motor removed helps gain access to the inside of the HVAC case.
12. Using the supplied ionizer bracket as a template, drill a 1/8” pilot hole as shown. Remove the bracket. It will be used at step 18 of the Ionizer Installation.
Note: Some HVAC cases may or may not have the shown case mounting bolt. If the case does not have one, use the supplied bolt in the ionizer kit to mount the bracket.
13. Using a 12.7 mm (1/2”) drill bit, drill the ionizer mounting hole.
Important: The use of a Uni-bit style bit works well. The use of a spade bit will produce excessive plastic chips and may cause the drain to get plugged.
Important: Remove all of the plastic flash around the ½” hole. Reach in through the blower motor area and use a mirror and/or feel to ensure that there is no plastic flash around the hole on the inside wall of the case.
Note: Use a vacuum to collect as many of the plastic chips as possible. The blower motor removed helps gain access to the inside of the HVAC case.
14. Reinstall the blower motor. Refer to Refer to Blower Motor Replacement in SI.
15. Connect the battery.
16. Close the face vents on the dash as well as the vents on the rear of the center console. Place a protective cover over the carpet under the blower to air distribution box duct and over the HVAC face (upper) vents. Set the HVAC temperature control to LO, air distribution to vent mode and blower speed to high (A/C off).
17. Insert the application tool into the drilled hole. Apply OxyVap™ at 65 psi (448 kPa).
• Apply the OxyVap to the evaporator core using applicator tool P/N 23372329. Move the wand up and down to obtain good coverage to the fin area. Turn the HVAC system to off.
• Allow the core to soak for 5 minutes.
• Rinse the empty bottle of OxyVap and fill with clean water. Rinse the evaporator core moving the applicator tool up and down with clean water until the bottle is empty with the blower turned on “High.”
• Using the applicator tool, blow compressed air on the evaporator core for one minute moving the applicator tool up and down to help remove excess water.
• Install the body plug, P/N 15632415, into the 19 mm (3/4”) hole with a thin coating of RTV.

4. Locate the violet/gray wire (circuit 539, K33 HVAC Control Module X2) in the instrument panel harness for power as shown and cut the wire.
Note: Within the same harness, there is a violet/white wire. Use caution to select the correct wire.
5. Using the supplied splice sleeves, crimp wire 1 from the supplied wire harness to the violet I/P harness and connect the other end of the violet wire to the connector.
Note: Stagger the crimps from the supplied wire harness to the instrument panel harness.
6. Locate the black wire (circuit 1450, K33 HVAC Control Module X2) in the instrument panel harness for ground and cut the wire.
7. Using the supplied splice sleeves, crimp wire 2 from the supplied wire harness to the black I/P harness and connect the other end of the black wire to the connector.
8. Apply heat to the splice sleeves to seal them.
9. Rewrap the I/P harness with the friction tape and seal with electrical tape.
10. Route the supplied wire harness (connector end) up towards the radio.
11. Connect the battery.
12. With ignition on, check for 12 volts at the Ionizer connector of the wire harness before connecting to the ionizer controller. (The Ionizer has no telltale signs that it is operational.) Also see item #31 for operational checks after installation.

25. Install the floor front air outlet duct – right side. Refer to Floor Front Air Outlet Duct Replacement – Right Side in SI.
26. Remove and install a new passenger cabin compartment carbon air filter.
27. Install the instrument panel compartment. Refer to Instrument Panel Compartment Replacement in SI.
28. Install the front floor console extension panel – right side. Refer to Front Floor Console Extension Panel Replacement – Right Side in SI.
29. Install the front side door sill trim plate. Refer to Front Side Door Sill Trim Plate Replacement in SI.
30. Enable the SIR. Refer to SIR Disabling and Enabling in SI.
Note: Check the ionizer for operation. There should be B+ available at the ionizer power supply (white wire terminal 1) with the HVAC system operating and the blower motor turned on. Also check the amp draw of the ionizer at the B+ available at the ionizer power supply (white wire terminal 1). Amp draw should be .03 +/- .005 amps.
31. If the condition is still present, and the musty odor condition has been verified, the evaporator core should be replaced. Part number 23375992 should be installed.
Note: Do not apply any coatings to the replacement evaporator.
