Page 7 of 29 REMOVABLE ROOF WATER LEAKS AT A-PILLAR (FRONT UPPER CORNER OF DOOR GLASS) 1. Verify the water leak condition. For testing, use only normally pressurized tap water from a standard size garden hose. 2. Reset the power window short drop function. Refer to the Owner's Guide. 3. Retest for water leak. a. If leak is no longer present return the vehicle to the customer. b. If leak is still present then proceed to Step 4. 4. Remove the removable roof and check that the weatherstrip corners at the top of the a-pillars near the windshield weatherstrips are seated/positioned correctly (Fig 6 ). Fig 6: Weatherstrip Corner At Top Of A-Pillar a. If gaps are present, correct by pushing/repositioning weatherstrip as needed. Reinstall the roof and water test. If the leak is corrected return vehicle to customer.
Page 8 of 29 b. If weatherstrips were seated correctly, proceed to Step 5. 5. Water, which enters the vehicle between the side weatherstrip and the door glass near the top of the a-pillar, can be repaired by adding seal stuffer, part number 2W6Z- 76025B52-AA. The part package contains 2 stuffers. Install one stuffer on each side of the vehicle following Steps 5-9. NOTE: SOME VEHICLES MAY ALREADY HAVE THE SEAL STUFFER INSTALLED. IF SEAL STUFFER IS ALREADY INSTALLED VERIFY THAT IT HAS BEEN POSITIONED CORRECTLY PER STEP 9. IF SEAL STUFFER IS NOT POSITIONED CORRECTLY REMOVE AND REPLACE WITH A NEW SEAL STUFFER FOLLOWING STEPS 5-9. 6. Remove the roof from the vehicle and place in the removable roof storage cart. 7. Dry all moisture and clean all dirt and debris from the weatherstrips on the roof. 8. Apply 3-4 small evenly placed dabs of Ford Trim and Weatherstrip Adhesive, part number TA-14, to one side of the seal stuffer. Do not coat the entire stuffer with adhesive. 9. Position the seal stuffer behind the secondary seal approximately 20 mm rearward from the front edge of the seal. For best results have an assistant open the weatherstrip so proper placement can be obtained (Fig 7 ) (the primary weatherstrip has been removed in the figure for clarity).
Page 9 of 29 Fig 7: Positioning Seal Stuffer Behind Secondary Seal 10. Install the roof and water test to verify the repair. 11. If water leak continues in the same location, the weatherstrips may require adjustment or the door glass may not be fully rolling up into the weatherstrip, Proceed to REMOVABLE ROOF LEAKS AROUND DOOR GLASS WEATHERSTRIPS. REMOVABLE ROOF LEAKS AROUND DOOR GLASS WEATHERSTRIPS Adjusting or repositioning the weatherstrips may repair water, which enters the vehicle between the side weatherstrips and the door glass.
Page 10 of 29 1. First, reset the power window short drop function. Refer to the Owner's Guide. Verify that the weatherstrips along the glass are uniformly pressing against the door glass. This can be done by moistening the weatherstrips with water and closing the door. The wet weatherstrips will clearly show their contact pattern against the glass. 2. Where no contact pattern is present, firmly grasp and pull the weatherstrip to the desired location to achieve a uniform seal against the glass. The weatherstrip is attached to metal flanges on the roof, which will bend slightly. a. If leak condition is corrected return vehicle to customer. b. If adjustments do not correct the condition, the door glass may not be fully rolling up into the weatherstrip, proceed to Step 3. 3. Make certain the windows are capable of completely seating into the weatherstrip. a. Open the door and manually trip the door latch closed. This will raise the glass with the short drop function. b. Measure the distance between the peaked edge on the rear of the door glass to the top of the belt molding seal. If greater than 9.5 mm (3/8"), the glass is not rolling up fully into the weatherstrips, proceed to Step 4. If 9.5 mm (3/8") or less, the glass is lifting properly. Verify weatherstrips are still positioned correctly (Fig 8 ).
Page 11 of 29 Fig 8: Measuring Between Door Glass & Belt Molding Seal 4. The glass may not mechanically roll up far enough to seal. a. Keep door open, and the window in the raised position from the short drop feature. b. Remove the door trim panel to access the rear glass adjustment nut. Refer to Workshop Manual, Section 501-05. c. Loosen the rear 10 mm regulator clamp bolt and pull upward on the glass until a maximum of 9.5 mm (3/8") can be measured between the peaked edge on the rear edge of the door glass and the top of the belt molding seal (Fig 8 ).

FOLLOWING THE STEPS IN THIS ARTICLE THAT PROVIDE ADJUSTMENT DETAILS CAN REPAIR MOST WATER LEAKS. 5. Roll down the windows and operate the convertible top down and back up. Once the top is at the windshield header and the pump motor begins to "stall", keep the button depressed for 2-3 seconds additional before latching the top. If the top is not completely positioned up, the top frame and weatherstrips will not be positioned correctly. Roll the windows up and water test. a. If leak condition is corrected return vehicle to customer. b. If leak is not corrected proceed to Step 6.
Page 24 of 29 6. Check for excessive gaps between the weatherstrips on the convertible top. Adjust the position of the weatherstrips on their mounting flange, or bend the mounting flange as needed to correct (Fig 15 -Fig 18 ). a. If leak condition is corrected return vehicle to customer. b. If leak is not corrected proceed to Step 7. 7. Lower the convertible top and check that the weatherstrip corners at the top of the a-pillars near the windshield header weatherstrips are seated/positioned correctly (Fig 19 ). Fig 19: Weatherstrip Corner At Top Of A-Pillar a. If gaps are present, correct by pushing/repositioning the weatherstrip as needed. Raise the roof and water test. If leak condition is corrected return vehicle to customer. b. If weatherstrips were seated correctly proceed to Step 8. 8. Make certain the windows are capable of completely seating into the weatherstrip.
Page 25 of 29 a. Raise the roof. Open the door and manually trip the door latch closed. This will raise the glass with the short drop function. b. Measure the distance between the peaked edge on the rear of the door glass to the top of the belt molding seal. If greater than 9.5 mm (3/8"), the glass is not rolling up fully into the weatherstrips, proceed to Step 12. If 9.5 mm (3/8") or less, proceed to Step 9 (Fig 20 ). Fig 20: Measuring Between Door Glass & Belt Molding Seal 9. Lift the outside door handle and trip the door latch open, which will drop the door glass. Close the affected door and measure and record the distance between the silkscreen on the door glass and the top of the belt molding seal. The measurement distance is not critical. The rule in the figure is for reference (Fig 21 ).
Page 26 of 29 Fig 21: Measuring Between Silkscreen & Belt Molding Seal 10. Open the affected door. Exert light hand pressure against the outside of the glass. Shut the door with normal force and keep pressure on the glass until the short-drop function raises the glass into the weatherstrip. Again measure between the silkscreen and the top of the belt molding seal (Fig 21 ). 11. If measurement is now greater than observed in Step 8, proceed to Step 13. If measurement stayed the same, proceed to Step 12. 12. The glass may not mechanically be able to roll up far enough to seal. a. Raise the roof. Open the affected door and command the system to roll the glass up with the short-drop feature. This is done by manually tripping the door latch. b. Remove the door trim panel to access the rear glass adjustment nut. Refer to Workshop Manual, Section 501-05. c. Loosen the rear 10 mm regulator clamp bolt and pull upward on the glass until a maximum of 9.5 mm (3/8") can be measured between the peaked edge on the rear of the door glass to the top of the belt molding seal.
Page 27 of 29 d. Torque the bolt to 12 N.m (9 lb-ft). e. Assemble the door trim panel; flip the door latch open to drop the glass and water test. f. If leak condition is corrected return vehicle to customer. g. If leak is not corrected proceed to Step 13. 13. The window motor may be stalling before the glass can properly seal. Strike "down and in" along the stitch bead on the edge of the convertible top, starting from the a-pillar area back approximately 50 cm (20") with a rubber mallet. This area is where the top of the glass penetrates a U-shaped channel in the weatherstrip. If the weatherstrip flange on the convertible top is not rolled inboard enough, the door glass will not properly enter the weatherstrip (Fig 22 ). Fig 22: Reshaping Weatherstrip Flange With Mallet 14. After the adjustment in Step 13 is made, normally open and close the door checking that the glass is rolling all the way up into the weatherstrip then water test. a. If leak condition is corrected return vehicle to customer. b. If leak is not corrected proceed to Step 15. 15. If the glass is still not fully entering the weatherstrips, adjust the channel in the rear portion of the second weatherstrip "up" to allow closure. This area of the weatherstrip is
Page 28 of 29 where it transitions from the channel along the roof to a compression seal along where the b-pillar would be present. Use the handle of a rubber mallet to bend the weatherstrip and convertible top flange "up" then water test (Fig 23 ). a. If leak condition is corrected return vehicle to customer. b. If leak is not corrected proceed to Step 16. Fig 23: Weatherstrip Transition From Roof To B-Pillar 16. Check that the weatherstrips are uniformly pressing against the door glass. This can be done by moistening the weatherstrips with water and closing the door. The wet weatherstrips will clearly show their contact pattern against the glass. This is critical along the rearward slope of the glass (b-pillar). 17. The weatherstrips are positioned on metal mounting flanges that are part of the convertible top frame. These flanges may be bent slightly to improve the weatherstrip pattern. To adjust, simply grasp the weatherstrip and move it inboard or outboard to improve contact against the glass.
