When replacing the HVAC actuator it will be necessary
to allow the HVAC control module to perform a
calibration process. When installing the HVAC actuator
be sure to perform one of the following:
NOTE
Do not adjust any controls on the HVAC
control module while the HVAC control
module is self-calibrating. If interrupted,
improper HVAC performance will result.
Preferred Method (w/Scan Tool)
1. Clear all DTCs.
2. Place the ignition switch in the OFF position.
3. Install the HVAC actuator.
4. Connect all previously disconnected components.
5. Start the vehicle.
6. With the scan tool, initiate the Motor Re-calibration
feature of the Heating and Air Conditioning Special
Functions menu.
7. Verify that no DTCs have set as current DTCs.
NOTE
Do not adjust any controls on the HVAC
control module while the HVAC control
module is self-calibrating. If interrupted,
improper HVAC performance will result.
Alternate Method (w/o Scan Tool)
1. Clear all DTCs.
2. Place the ignition switch to the OFF position.
3. Install the HVAC actuator.
4. Connect all previously disconnected components.
5. Remove the HVAC/ECAS fuse for a minimum of 10
seconds.
6. Install the HVAC/ECAS fuse.
7. Start the vehicle.
8. Wait 40 seconds for the HVAC control module to
self-calibrate.
9. Verify that no DTCs have set as current DTCs.

Leak Testing
Special tool
J 39400-A Halogen Leak Detector
J 41447 R-134A A/C Tracer Dye-Box of 24
J 42220 Universal 12V Leak Detection Lamp
J 43872 Fluorescent Dye Cleaner
J 46297 A/C Dye Injector Kit
J 46297-12 Replacement Dye Cartridges
Refrigerant Leak Testing
NOTE
This vehicle is now manufactured with
fluorescent dye installed directly into the air
conditioning (A/C) system.
The fluorescent dye mixes and flows with the
polyalkylene glycol (PAG) oil throughout the refrigerant
system.
Verifying some passive leaks may require using the J
39400-A, even though the A/C system contains
fluorescent dye.
The only time that adding additional fluorescent dye is
required is after flushing the A/C system.
Fluorescent Leak Detector
Fluorescent dye will assist in locating any leaks in the A/
C system.
NOTE
PAG oil is water soluble.
• Condensation on the evaporator core or the
refrigerant lines may wash the PAG oil and
fluorescent dye away from the actual leak.
Condensation may also carry dye through the HVAC
module drain.
• Leaks in the A/C system will be indicated in a light
green or yellow color when using the leak detection
lamp.
Use the leak detection lamp in the following areas:
– All fittings or connections that use seal washers or
O-rings
– All of the A/C components
– The A/C compressor shaft seal
– The A/C hoses and pressure switches
– The HVAC module drain tube, if the evaporator
core is suspected of leaking
– The service port sealing caps
The sealing cap is the primary seal for the service
ports.
• Follow the instructions supplied with the J 42220.
• To prevent false diagnosis in the future, thoroughly
clean the residual dye from any area where leaks
were found. Use a rag and the approved J 43872.
