Subject: Headlamp Opening Interference

Number: 69-T-31, Section I
Date: May 6, 1969
To: ALL CHEVROLET DEALERS
A condition could occur on 1969 Corvettes which would restrict the opening of the headlamp doors. This is caused by wind pressure distorting the plastic headlamp shield enough to allow interference between the shield and the lower lip of the headlamp bezel at highway speeds.
The driver is aware of this problem when the red indicator warning lamp does not go out informing him of a headlamp problem. Reduction of speed and switching headlamps of and back on again will allow full opening of the headlamp doors.
This problem may be corrected in the field by replacing the present headlamp shields with a new shield which has revised trim lines to clear the headlamp bezels.
