Affected: 1987-88 BONNEVILLE

FIGURE 1:

If a comment is received regarding air noise with the Astro Roof glass fully open at 35-55 mph, a new air deflector, Part Number 16605193 with three slots (see Figure 1) may be installed to minimize air noise..

The new deflector is currently being installed in production and will fit 1987 thru 1988 production.

FIGURE 2:

SERVICE PROCEDURE

Installation of the deflector requires the removal of the sunroof housing, per the 1988 Bonneville Service Manual, Section 8C-54 - Roof.

The new deflector has an actuator arm with an offset leg (see Figure 2). This deflector can be used without any change on 1987 into early 1988 production; these use the offset leg. Later 1988 production does not use an offset leg, and requires cutting off the offset (See Figure 2, dotted line).
WARRANTY INFORMATION

Use applicable labor operation and time from the Labor Time Guide.

If necessary to remove offset leg, list .3 hour in "Other Labor Hours" Column.
