Location of Sunshade, Air Deflector, Shield.
Isolation of Sunshade, Air Deflector, ShieldTo isolate components and eliminate rattles in the rest of the sunroof assembly, complete all of the following steps on 1988 and 1989 vehicles. Add loop material (soft loop half of hook-and-loop fastener system, such as Velcro or Scotchmate Hook and Loop Fastener, 3M P/N 06480) in the following locations as required:
1. Remove sunshade. Open glass panel part way.
2. Add loop material (40 mm long) at the front of the glass panel on the underside. Refer to Figure 4 for locations. This prevents air deflector rattles against the bottom of the glass panel.
3. Add a small pad (10 mm) of loop material at the top front corners of the track. Locate pad so deflector rests on it when closed.
4. Add loop material, approximately 70 mm long, on the top (back side) of the sunshade in the area of the reinforcement. Refer to Figure 5 for locations.
5. Add one piece of loop material at the rear of the sunshade, approximately 50 mm long, wrapped around the edge at the center.
6. Reinstall sunshade.

Sunshade "Ticking" Noise
Some sunshades on 1988 through early 1990 may exhibit a "ticking" noise when traveling over bumps or due to road vibrations. This sound may be caused by a loose attachment of the sunshade reinforcement.
To determine if the sunshade is the cause of such a noise, carefully remove it from the vehicle. Holding the sunshade on either side, gently twist back and forth while listening for the sound at the rear of the reinforcement. If a "ticking" sound is heard, perform the following procedure:
1. Place the sunshade upside down on a clean surface.
2. Using a chisel and a hammer, restrike the 12 toggle locks located at the sides and along the back of the reinforcement. Strike each toggle area twice, in an "X" pattern, as shown in Figure 6.
3. Apply a small bead of standard, black weatherstrip adhesive along the rear edge of the reinforcement.

Note:
A new sunshade with a welded reinforcement was implemented in production in October, 1989. Welded sunshades are easily identified due to the lack of the toggle lock "bumps" around the reinforcement.
