NOTE: This procedure addresses water ingress through the trunk lid and not due to water entering the vehicle while the trunk was opened in the rain.

NOTE: Although the figures in this procedure highlight one side of the trunk lid, this procedure must be performed on both sides (LH and RH) of the trunk lid.

PROCEDURE

Remove the trunk lid trim (refer to TRIM - LID - TRUNK - REMOVE AND REPLACE ).
Remove the LH and RH rear fog/reverse lights (refer to LIGHT - FOG/REVERSE - REAR - LH - REMOVE AND REPLACE ).
Remove and discard the factory foams (x2) (Figures 1-4) located under the LH and RH lamp can panels inside the trunk lid.
CAUTION: Wear appropriate eye safety glasses and protective earplugs as Personal Protection Equipment (PPE).
Prepare the caulking gun (1939249-00-A) with the 5510 white sealant (1939248-00-A) (Figure 5). Cut an approximately 4 mm wide opening on the sealant dispensing tube (Figure 6) using a retractable blade knife.
Apply the sealant on top of the LH and RH lamp can panels located inside the trunk assembly (Figures 7-10), and then spread the sealant bead with your finger (Figures 11 and 12) while wearing a nitrile glove. Apply several sealant beads as needed.
CAUTION: Use nitrile gloves as PPE for the remainder of this procedure.

NOTE: Make sure to apply the sealant between the panels (Figure 12).
Apply the sealant on the sides and the back side of the LH and RH lamp can panels located inside the trunk lid (Figures 13-18). Spread the sealant bead with your finger while wearing a nitrile glove. Apply several sealant beads as needed.
NOTE: Use the dauber (1939250-00-A) in tight spaces (Figure 16).

NOTE: Make sure to apply the sealant between the panels (Figure 18).
Apply the sealant on the bottom side of the LH and RH lamp can panels located inside the trunk lid (Figures 19 and 20). Apply several sealant beads as needed.
NOTE: Use the dauber to apply the sealant in small spaces.

NOTE: Make sure to apply the sealant between the panels (Figure 21).
Inspect the trunk lid seams: Locate openings and pin holes in the highlighted areas (Figures 22-27).
Use a plastic trim tool to remove any previously applied non-factory sealants in the highlighted areas, if present (Figures 28-31).
CAUTION: Do NOT remove factory sealant. To differentiate between factory sealant and non-factory sealant, factory sealant is painted over and is harder to remove, and non-factory sealant is usually clear and easier to remove than factory sealant.

NOTE: Use adhesive remover, as needed.
Clean the trunk lid seams areas with Isopropyl Alcohol (IPA) wipes (Figures 32 and 33).
Apply sealant ONLY on the openings and pin holes found during the inspection (Figures 34 and 35).
CAUTION: Do NOT apply sealant to the entire trunk lid.
Remove excess sealant with a clean, dry microfiber cloth. Allow 1 hour for the sealant to fully cure (Figures 36-41).
CAUTION: Do not use chemicals to remove excess sealant.

NOTE: The sealant must be allowed to cure for 1 hour because touch-up paint will be applied onto it later in this procedure.
Apply sealant on the upper and lower panel mating surfaces for the LH and RH sides (Figures 42-45). Allow 1 hour for the sealant to fully cure.
NOTE: Apply sealant with your finger while wearing a nitrile glove, and then work sealant onto the factory sealant.

NOTE: Make sure to apply the sealant between the panel mating surfaces (Figure 45).

NOTE: The sealant must be allowed to cure for 1 hour because touch-up paint will be applied onto it later in this procedure.
Remove excess sealant from the upper and lower panel mating surfaces with a clean, dry microfiber cloth (Figure 46). Allow 1 hour for the sealant to fully cure.
CAUTION: Do not use chemicals to remove excess sealant.

NOTE: The sealant must be allowed to cure for 1 hour because touch-up paint will be applied onto it later in this procedure.
Apply touch-up paint onto newly sealed areas (Figure 47-50).
NOTE: Make sure sealant is dry to the touch before touch-up paint is applied.
Inspect the overall condition of the trunk seal. If the trunk seal is compromised (Figure 51), replace the seal (refer to SEAL - TRUNK - REMOVE AND REPLACE ).
Close the trunk.
Verify that the trunk seal fully contacts the trunk lid and that there are no visible gaps (Figures 52 and 53).
NOTE: With assistance, shine a flashlight from the exterior and make sure no light is visible on the inside. If light is visible, then replace the trunk seal and repeat this step. If light is still visible after the replacement of the trunk seal, then perform trunk seal adjustment, as needed.
Open the trunk.
Put the RH rear fog/reverse light upside down on a padded surface (Figure 54).
Remove and discard the gaskets for the RH light connector (Figure 55) and mounting stud (Figure 56), and then replace them with new ones (Figures 57 and 58).
Repeat steps 20 and 21 for the LH rear fog/reverse light.
Install the LH and RH rear fog/reverse lights (refer to LIGHT - FOG/REVERSE - REAR - LH - REMOVE AND REPLACE ).
Install the trunk lid trim (refer to TRIM - LID - TRUNK - REMOVE AND REPLACE )
