5. Lubricate all 10 module compensators/attachments areas with GM Super lube (P/N 12346241 [in Canada use P/N 10953474]) prior to
reinstallation of the headliner (refer to figure 7).
Caution
Be cautious when spraying GM super lube. To avoid any damage to the interior trim, cover all exposed areas before spraying. While spraying, use
a shop towel with the other hand to catch any drips and pat the sprayed area to remove any excess lubricant.
6. If the vehicle was built before May 9th, 2007, verify that the flock tape is in place on the headliner as described in Condition #10.
7. Test drive the vehicle to confirm that all noises have been eliminated.
8. Reinstall the headliner.
Condition # 2
Condition #2
Some customers may comment on wind noise coming from the glass panel areas of the sunroof. This condition could also be reported as a HVAC blower
motor whistle type noise that changes with HVAC blower fan speed.
Cause
This condition may be caused by one of more glass panels out of adjustment and not sealing properly.
Correction
VERIFY THE CUSTOMER CONCERN - Windnoise and/or HVAC blower/whistle type noise can vary depending on the blower fan speed setting.
Higher fan speeds increase cabin pressure allowing more air flow out of the cabin through marginal sealing areas. To properly diagnose, it is important to
know at what vehicle speeds and/or what fan speed settings the windnoise occurs. Another diagnostic method to detect panel to panel air leakage, while
the vehicle is sitting in the service stall, is by tracing the perimeter of each glass panel with the open hose end portion of a stethoscope-type tool with all
the vehicle doors and windows closed and the HVAC blower speed on high.
