SUBJECT: I/P TOP COVER (UPPER) - POOR FIT TO I/P CARRIER (LOWER) (FILE 3-4mm OF MATERIAL OFF)

VEHICLES AFFECTED: 1990-91 'C'

Some 1990-1991 DeVilles and Fleetwoods may experience a large gap between the instrument panel top cover (upper) to the instrument panel carrier (lower) at the left A/C outlet. Refer to Figure 1. This may be caused by interference between the A/C valve housing and lower surface. To repair this condition use the following procedure:

1. Remove I/P top cover. Refer to Section 8C in the Service Information Manual.

2. Place I/P top cover upside down on a clean, non-abrasive surface.

3. Remove the two screws securing the driver-side A/C valve to the top cover. Refer to Figure 2.

4. Elongate the mounting holes to allow for tight fit of the A/C valve to the top cover. Refer to Figure 3.

5. File approximately 3-4mm of material off of the driver-side A/C duct shut-off valve in the area indicated. Refer to Figure 3.

6. Install driver-side A/C duct shut-off valve to upper cover. Refer to Figure 4.

7. Remove cluster filler trim.

8. Elongate the mounting hole approximately 2mm to allow filler trim to move upward. Refer to Figure 5.

9. Install filler trim to upper cover.

10. Position upper cover to instrument panel lower.

11. Install screws to outboard A/C outlets while holding top cover down tight to the carrier. Refer to Figure 6.

12. Install screws to inboard A/C outlets.

13. Install screws in the glove box.

14. Install screws to the windshield defroster grille.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
