Moon Roof - Won't Close/Wind Noise
83ford9 Article No. 83-18-2MOON ROOF - WINDNOISE - ROOF CONTOUR HIGH - WILL NOT FULLY CLOSE
LINCOLN-MERCURY 1983 CONTINENTAL
Some 1983 Continental's equipped with a power moon roof may exhibit one or more of several symptoms, such as windnoise, high roof contour, moon roof will not fully close or rear guide pins become disengaged, from their related (cam blocks) lifter assemblies.
These symptoms are most generally caused by overcrowned roof or marginal engagement of the rear guide pins. When performing a service for any of the abovementioned symptoms, the roof contour must be checked and corrected first (Steps (1) through (8) of the following procedure) before proceeding with the appropriate service procedure.
Procedure to Correct Power Moon Roof Overcrowned Roof Panel/Rear Guide Pin Engagement Continental - 1983
1. Overcrowned Roof Panel.
The following steps one to eight, inclusive, are required in the procedure because marginal rear guide pin engagement may result from previous glass panel adjustment attempts to correct a windnoise condition caused by an overcrowned roof panel.
1. Move the moon roof (sliding glass panel assembly) to the closed position.
2. With the sliding glass panel assembly in the closed position, inspect for an overcrowned roof panel at the rear of the moon roof opening (i.e., the roof panel contour mismatches the glass panel contour).
a. If an overcrowned roof panel condition exists, perform service steps #3 through #8.
b. If an overcrowned roof panel condition does not exist, perform service steps #9 through #16.
3. Remove the sliding glass panel assembly in accordance with the appropriate Body Car Shop Manual, Section 46-05. Lay it on a protected surface.

4. Through the opening in the roof panel assembly, grasp both the roof panel (outer) and the roof trim panel (interior side) in the dome lamp area and overbend (reshape) the sheet metal by applying downward pressure, as shown in Figure 2.
CAUTION: THIS OVERBENDING PROCESS REQUIRES A JUDGEMENTAL TECHNIQUE; THUS IT
MUST BE DONE CAREFULLY, AS INDISCRIMINATE OVERBENDING COULD RESULT IN PERCEPTIBLE DISTORTION OF THE ROOF PANEL SHEET METAL, REQUIRING COSTLY METAL REFINISHING SERVICE.

5. Install the sliding glass panel assembly.
CAUTION: DO NOT USE THE LIFTERS AS HANDLES OR THEY WILL SPREAD OUTWARD CAUSING A RECURRENCE OF THE SUBJECT CONDITION.
6. Adjust the sliding glass panel assembly, as described on Figure 3.
7. Check to ensure the roof panel contour matches the glass panel contour. In the event contour mismatch still exists, repeat steps #3 through #7 as required.
8. After achieving an acceptable fit, road test car.

II. Rear Guide Pin Engagement
9. Repeat step #3 except invert the sliding glass panel assembly as shown on Figure 4.
10. With the sliding glass panel assembly in the inverted position, and using a grease marker and the fourth retaining nut and washer assembly as a centerline locater, mark the glass surface in two places (one mark opposite each integral lifter bracket). Refer to Figure 4.
11. Measure and record the distance between the locater mark and the top of the lifter front bracket.
12. Repeat step #11 for the lifter rear bracket.
13. Repeat steps #11 and #12 for the opposite side.
FIGURE 5:
14. If the measured distance exceeds 446.0 mm (17-9/16"), move the affected bracket(s) inward as shown on Figure 5 until the correct dimension is achieved.

CAUTION: DO NOT USE THE LIFTERS AS HANDLES OR THEY WILL SPREAD OUTWARD CAUSING A RECURRENCE OF THE SUBJECT CONDITION.
^ Adjust the sliding glass panel assembly, as described on Figure 3.
15. Cycle the sliding glass panel assembly several times to ensure proper operation.
