8. IMPORTANT: Wind/whistle noise, air leaks and possible water leaks on the C3Y panoramic sunroof when closed. The easiest way to identify
the location of the air leak is to use a rubber hose against your ear in order to listen for the air leak. Using a rubber hose, 1/2 inch diameter 3 feet
long, listen around all the sunroof window sealing locations while all the door, windows and the sunroof window panels are closed, with the
HVAC blower on high. It should be note that some leakage will be heard at the "T" (1) joints on vehicles without a customer complaint.
Perform the air leak test, as noted above.
9. Inspect the operation of the sunroof window.
10. Raise and install the headliner. Refer to Headlining Trim Panel Replacement.
