Allure/Lacrosse Wind Noise/Road Noise Conditions
Allure/LaCrosse Wind Noise/Road Noise ConditionsRoad test the vehicle in order to verify what condition(s) apply.
Condition #1
Wind rush around the door appliques.
Cause
The door applique may not be seated all the way. The leading edge of the applique should not gap to the glass run channel seal.
Correction
Press on the applique in three locations (top, middle, bottom). There should be no click sounds. A click indicates that the tab on the applique was not fully seated into the clip on the reveal molding.
Condition #2
Wind rush from the hood to the grille.
Cause
There may be too much gap between the hood and the grille.
Correction
Refit the hood to ensure contact to the seal. There should be light contact between the hood seal and the hood. Also, make sure that the grille is flush and even across.
Condition #3
Road noise or wind noise around the inner belt seal.
Cause
The inner belt seal may be installed too far forward or too far rearward. There should be no gap or hole between the run channel and the inner belt seal.
Correction
Remove the door trim panel and reposition the inner belt seal as necessary.
Condition #4
Wind noise around the window run channel seal.
Cause
The run channel may not be seated all the way.
Correction
Fully seat the run channel to the door frame.
Condition #5
Wind rush from the wipers or the cowl panel.
Cause
The wiper arms may not be installed low enough on the windshield or the cowl panel may not be seated to the windshield
Correction
Check to make sure the tip of the wiper blade is resting on the white or black dot on the windshield. The white dot will be a painted dot on the windshield and if the white dot is not present there will be a black dot in the windshield. If the cowl panel is not seated to the windshield check to make sure the clips on the underside of the cowl panel are under the windshield.
Condition #6
Wind noise or wind rush from the "B" pillar.
Cause
The door secondary seal may not be in contact with the front door.
Correction
Adjust the door for proper contact. Place a piece of paper (such as a dollar bill) on the seal and close the door. There should be a constant drag when pulling the paper between the seal and the door frame.
Condition #7
Wind rush from the front of the door.
Cause
The front door may be outboard of the front fender.
Correction
Make sure the front fender is outboard of the leading edge of the front door. Adjust the front fender outboard of the door.
Condition #8
Wind noise or wind rush around the top of the door frame.
Cause
The door upper auxiliary seal may not be in contact with the body.
Correction
There should be no gap between the upper auxiliary seal and the body. Place a piece of paper (such as a dollar bill) on the auxiliary seal and close the door. There should be a constant drag when pulling the paper between the auxiliary seal and the body.
If the lip is bent in a local area, try a heat gun to straighten the lip out. Otherwise, the molding will have to be replaced. If the lip is not bent, refit the door by raising the door so the molding lip makes contact with the roof.
Condition #9
Wind noise or wind rush from the inner belt seal.
Cause
The inner belt seal may not be in contact with the door glass.
Correction
Check if it is due to a localized bulge in the door glass and replace the glass if a bulge is present. Otherwise, try a heat gun on the inner belt molding lip. Replace the inner belt molding if required.
