Wind Buffeting Noise With a Rear Window Down - keywords door glass open

This PI was superseded to update model years. Please discard PIT4355.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Some customers may comment of a helicopter type noise when a rear window is lowered. This is known as buffeting and it is a low frequency, high volume wind noise that may occur in a moving vehicle with a rear window open.

This is a normal characteristic of this vehicle, but the concern can be minimized by lowering a front door glass approximately 1 to 2 inches. Installation of accessory weather deflectors along the front door glass may also be effective in alleviating the buffeting noise.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
