    have you tried using a pipe cleaner to clean teh chanels in your weather stripping??? they can get clogged and stop allowing water the flow through them... another thing is to armor all them to keep them from dry rotting... other than that check window alingment...

    #00-08-66-001: Water Intrusion Into Rear Compartment (Replace Weatherstrip/Adjust Doors) - (Jan 5, 2000)

    Subject: Water Intrusion into Rear Compartment (Replace Primary Weatherstrip/Adjust Doors if Necessary)

    Models: 1999-2000 Cadillac Escalade
    1999-2000 Chevrolet and GMC C/K Utility Models (Tahoe Z71 and Limited, Yukon Denali)
    1999 Chevrolet and GMC C/K Utility Models (Tahoe, Suburban, Yukon)
    With Cargo Doors or Endgate (RPOs ZW9, E55)
    Built Prior to the following Production Dates:

    Condition
    Some owners of the above listed vehicles may comment on water entering into the rear compartment area.

    Cause

    Cargo Doors

    The following conditions may cause water intrusion:
    The weatherstrip carrier may be allowing water to enter at the upper radius of the door opening, traveling down to the sill area into the rear compartment.
    The rear door may be misaligned at the top, outer edge, causing "overcompression" of the primary and auxiliary seals at the left rear defogger (RPO C49) switch area.
    The rear door may be misaligned side-to-side, causing poor contact to the auxiliary weatherstrip at the top of the door.
    The left rear door vertical weatherstrip mucket (insulator) may not be horizontal on contact with the primary weatherstrip.

    Endgate

    The current weatherstrip may allow water intrusion at the electrical contact on the left and right side of the rear compartment.

    Correction

    Cargo Doors

    A new rear cargo door opening primary weatherstrip has been developed to correct this condition. This weatherstrip has a mastic (pastelike) sealer in the carrier that should address the water intrusion provided there are no other existing door conditions. Replace the primary weatherstrip on affected vehicles using the following procedure and the part number listed below. Some interior trim panels will need to be removed in order to replace the weatherstrip. Refer to the Interior Trim subsection of the Service Manual.

    Cargo Door Inspection and Correction

    Inspect the doors using the following steps and correct as necessary:
    Verify that the top outside corner of the doors are not tight to the body. Place a rubber mallet halfway between the upper hinge and the top of the door and attempt to close the door on the mallet. The gap between the body and the doors should be between 6-8 mm (0.24-0.32 in) at the top outboard corners.

    Notice: Do not apply too much pressure. This may cause the window to break under severe stress.
    If the doors are outboard, apply inward and downward pressure to the top inside edge of the door while in the open position.
    Verify that the left rear door weatherstrip mucket (insulator) is horizontal when contacting the primary weatherstrip. Adjust the mucket (insulator) if necessary.

    Endgate

    A new endgate opening primary weatherstrip has been developed to correct this condition. This weatherstrip has solid foam reinforcement inside the carrier on the left and right side, at the electrical contact area, that should prevent the weatherstrip from pulling away from the body. Replace the primary weatherstrip on affected vehicles using the following procedure and the part number listed below. Some interior trim panels will need to be removed in order to replace the weatherstrip. Refer to the Interior Trim subsection of the Service Manual.

    Weatherstrip Replacement (Cargo Door Models)

    Use the following steps to replace the cargo door opening primary weatherstrip:

    1. Open the back doors.
    2. Remove the spare tire. Refer to the Tires and Wheels subsection of the Service Manual.
    3. Remove the RH and the LH rear corner upper garnish moldings.
    4. Remove the RH and the LH rear corner lower garnish moldings and the rear sill trim as an assembly.
    5. Remove the rear upper body opening molding.
    6. Remove the back door opening surround weatherstrip from the pinchweld flange.

    7.1. Align the mark (2) on the weatherstrip to align with the center of the LH striker bolt hole (1).
    7.2. Push the weatherstrip onto the flange working outward in both directions (3). Ensure that the weatherstrip is secure in both corners.
    7.3. Push the weatherstrip down both sides of the outer flanges to the lower corners (4).
    7.4. Install the weatherstrip to the center of the lower door opening flange (5).
    7.5. Push the excess loops of the weatherstrip from the center, outward to corners (6).
    7.6. Push the weatherstrip securely around the perimeter of the door opening flange.
    8. Install the rear upper body opening molding.
    9. Install the RH and the LH rear corner lower garnish moldings and rear sill trim as an assembly.
    10. Install the RH and the LH rear corner upper garnish moldings.
    11. Install the spare tire. Refer to the Tires and Wheels subsection of the Service Manual.
