SUBJECT: ASTRO ROOF WINDNOISE

MODELS AFFECTED: 1985-88 ELECTRA/PARK AVENUES WITH ASTRO ROOF OPTION

FIGURE 1:

If a comment is received regarding an 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 1985 thru 1988 production.

FIGURE 2:

SERVICE PROCEDURE

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

The new deflector has an actuator arm with an offset leg (See Figure 2). This deflector can be used without modification on 1985 into early 1988 production; these use the offset leg. Later 1988 production does not use an offset leg, and require cutting off offset (See Figure 2, dotted line).
