There is a buzz, moan type or a sound similar to that of a Kazoo or a Reed. This condition usually happens at highway speeds with temperatures below 4°C (40°F) and more pronounced if there is a good cross wind.
The primary door weatherstrip lip may vibrate against the "A" pillar reveal molding.
Pull the primary seal weatherstrip back, clean and apply two-way tape 130 mm (12 in) long to the weatherstrip lip. Refer to the illustration above. Clean and then seat the primary seal to the "A" pillar.
Road noise, windnoise or the windshield fogs up on the right hand side.
A foaming operation may have been missed at the bottom of the "A" pillar. Open the hood and look for the foam in the illustration shown above.
From the inside of the vehicle, place duct tape horizontally in the hole so that when the foam is applied, it doesn't drop down into the dash. Apply Kent Ure-foam™ Expandable Foam, P/N P10630, or 3M™ Automix™ flexible foam, P/N 08463, to the bottom of the "A" pillar. Refer to the illustration above. Apply a second tube from outside the vehicle. Refer to the foam in the illustration under the cause.
There is windnoise from around the top of the front doors.
The primary seal might not be making good contact to the door surface. Check the seal contact with the dollar bill method.
Pull the primary seal down and measure the distance between the door surface and the body. Refer to the illustration above. Adjust the door striker to achieve 15 mm (9/16 in) between the door and the hem flange.
There is windnoise from the sliding side door.
The sliding side door may be outboard of the front door.
Adjust the sliding side door inboard 1 mm of the front door.
There is windnoise from the sliding side door glass.
There may be a gap in the sliding side door glass urethane.
Clean the leak area and reseal with urethane.
There is a windrush from the sliding side door glass.
The sliding side door glass is sticking outboard from the sliding side door outer sheet metal too far.
Tape off the glass to verify. If that corrects the condition, it will be necessary to remove the glass and reset it in the opening.
There is water running down the "A" pillar.
Pull the primary seal back at the top of the door and make sure that the piece of tape is attached to the hem flange.
If the piece of tape is loose, try and press it down or apply weatherstrip adhesive under the tape. Refer to the illustration for tape location.
There is water at the bottom of the front door.
The bottom of the water deflector may not be sealed to the door frame. Refer to the illustration above.
Look at the seal on the water deflector to make sure it is not dirty. Clean the door surface and reapply the water deflector to the door. If the deflector does not stick, it will be necessary to install a new one.
Water settles in the trim around the rear door striker. Refer to the illustration above.
The lift gate emblem studs may not be sealed. Refer to the illustration above.
Clean the studs off and seal with weatherstrip adhesive.
The headliner is wet or water is coming out of the "D" pillar trim to rear quarter trim.
The rear door wire pass through grommet may not be seated to the body. Refer to the illustration above.
Reseat the end of the grommet.
Water may be dripping from the "D" pillar trim to rear quarter trim or the rear carpet is wet.
The rear door primary seal may not be seated to the body. Refer to the arrow in the illustration above.
Fully seat the primary weatherstrip.
