# 6 - # 12
Condition 7Third door waterleak to the primary seal.
Cause
Third door waterleaks are generally caused by insufficient compression at the top of the door or by an improperly seated third door weatherstrip.
Correction A
Repair insufficient compression by adding an additional piece of itch tape behind the secondary weatherstrip. Refer to the illustration shown. A double thickness is supplied at the factory in this location. Adding one more thickness will stop some leaks. If adding itch tape does not stop the leak, bend the top of the door slightly so that it contacts the secondary seal.
Correction B
Third door weatherstrip related leaks are caused by the bottom push pin not being seated (refer to the illustration shown), or by a gap anywhere along the vertical surface of the seal. If the bottom pin is seated, remove the seal and reinstall using the following sequence.
^ Seat the upper weatherstrip pin.
^ Seat the lower weatherstrip pin.
^ Seat the vertical portion of the weatherstrip onto the third door flange. Seating the vertical portion of the seal before installing the bottom pin will allow the seal to stretch, which causes a gap just above the bottom pin.
Condition 8
Carpet wet in the rear.
Cause
Sealer under the roof molding may have a void in it. Refer to the illustration shown.
Correction
Test for a leak before removing the roof ditch molding. For pickups, remove the trim and insert air into the inside "C" pillar corner while applying soapy water to the suspected area of the roof. Dry and seal as necessary. For utilities, test for a void using air forced from inside the vehicle while spraying soapy water along roof seam. Air can be forced up the "D" pillar behind the trim panel, or through the top weatherstrip attachment hole in the "B" pillar for two-door utilities and behind the trim on "C" pillar for four-door utilities. Refer to the illustration shown. Clean the area with one of the cleaners listed and seal the area with one of the sealers listed.
Condition 9
Carpet wet in the rear and or in the corners at the base of the "C" pillar.
Cause
There may be a void in the body seam below the window. Refer to the arrow in the illustration.
Correction
Clean, dry and reseal with one of the sealers listed.
Condition 10
Rear floor wet.
Cause A
There may be a void in the roof seam sealer.
Cause B
There may be a void in the urethane around the back glass (Pickup).
Cause C
The vent window may have a bent flange or it may be mispositioned.
Correction A
For utilities, test for a void using air forced from inside the vehicle while spraying soapy water along the roof seam. Air can be forced up the "D" pillar behind the trim panel, or through the top weatherstrip attaching hole in the "B" pillar for two door utilities and behind the trim on the "C" pillar for four door utilities. Refer to the illustration shown. Clean, dry and reseal with one of the sealers listed.
Correction B
While leaks can occur at any point around the back glass, the upper left radius of the back glass opening is the point that should be inspected first. Leaks will surface at this location when the urethane bead is pushed out of the correct sealing path. Generally, the urethane bead can be repaired by injecting urethane into the void.
Correction C
Inspect the primary weatherstrip seal in order to verify that it is seated properly, especially at the flange corners. Ensure that the positioning holes are properly sealed and that there is no damage to the flange as well.
^ A damaged flange can cause a loss of seal compression.
^ Positioning holes are the attaching rivets at the front. If they are loose or misinstalled, drill out the loose rivet and install a new one. A new rivet usually does not require additional sealer.
Condition 11
Rear floor wet (1/4 Window Pickup).
Cause
Leaks around the 1/4 window are a result of the weatherstrip being damaged, not properly seated or not properly aligned at the butt joint.
Correction
^ Inspect the primary weatherstrip seal in order to verify that it is seated properly, especially at the flange corners.
^ Ensure that the positioning holes are properly sealed and that the sheet metal flange is not misaligned with the inside sheet metal further into the window opening than outer. If the inside sheet metal extends into the window opening farther than outer, grind down the excess metal to meet the outer flange.
^ Inspect the seal in order to verify that it has not been impacted during the quarter trim panel installation process. In this instance, the weatherstrip will exhibit a slight bulge on the visible surface, and may appear slightly twisted at the impact point. Properly seat the weatherstrip. In some cases, the weatherstrip may need to be replaced.
^ If the leak path visibly permeates from the butt joint of the weatherstrip, adjust the joint so that all mating surfaces are parallel and make an unbroken transition.
Condition 12
Water at the base of the "D" pillar.
Cause
1. Inspect for voids in the seam sealer in the hatch opening or the primary seal weatherstrip to make sure it is properly seated, not warped or deformed.
2. The rear high mount stop lamp may be loose.
3. The pressure relief valve may be loose.
Correction
1. Seal as necessary, using seam sealer at the joints and thumb grade at the corners.
2. Secure the rear high mount stop lamp properly.
3. Secure the pressure relief valve properly.
