Condition
Cause
Some customers may comment on hearing a tapping,
clicking or ticking noise at the windshield area. This
condition occurs more frequently while driving at
highway speeds and could be exaggerated on vehicles
with front bug guard deflectors.
This condition may be caused by air/wind causing the
windshield side reveal moldings to move, generating a
noise.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
