# SUNVISOR TO MAP LIGHT HOUSING INTERFERENCE

1989 DE VILLES AND FLEETWOODS

Some 1989 DeVilles and Fleetwoods may experience a condition where the sun visors may rub or interfere with the map light housing and/or the sun visor may "rollout" from the map light housing jaw when cycling up and down. To improve sun visor interference use the following procedure:

1. Remove visor from car at A-Pillar. Disconnect visor hot-lead from body harness. Refer to Figure 1.

2. Set visor on clean and protected work surface.

3. Remove rubber roller tip from tip pin.

4. Grasp tip pin firmly with pliers while holding visor, wiggle tip pin to loosen, and pull tip pin out.

#### IMPORTANT: Grasp tip pin in rubber tip area to prevent scratching tip pin body.

5. Using hot air gun on medium setting, warm nose area of visor directing air toward seam on visor tip pin area. Watch fabric for signs of discoloration or melting. Stop immediately at first signs of discoloration or melting.

6. Using a flat-head screwdriver untuck fabric along entire tip pin edge, refer to Figure 2.

7. Pull fabric back to expose approximately 1/2 inch of plastic core.

8. Measure 3-4mm from inboard edge of visor and cut this amount off with a band saw or hacksaw, refer to Figure 3.

9. File all edges including tip pin hole.

10. Trim excess fabric material while leaving enough to tuck back into seam, approximately 3-4mm.

11. Stretch fabric over plastic core and tuck into seam with flat-head screwdriver.

12. Push remaining fabric into tip pin hole.

13. Reinsert tip pin by firmly pushing into tip pin hole.

14. Install rubber roller tip.

For warranty purposes use Labor Operation T6362 at .4 hour for both visors.

To improve sun visor retention at the map light housing jaw use the following procedure:

1. Loosen three sun visor retaining screws and remove outboard screw.

2. At outboard screw, place a 1/8 inch thick washer or shim.

3. Tighten sun visor retaining screws.

4. If visor is still angled downward, add another shim using steps 1 through 3.

For warranty purposes use Labor Operation T6363 at .3 hour for one or both.
