Liftgate Glass (Remove and Replace)
Correction Code 10204002
Warning
To avoid personal injury, wear
cut-resistant gloves when performing this operation.
Note
Use Dow Betaseal Express fast-curing
glass adhesive to perform this procedure.
Special tool recommended for this procedure:
Supplier | Part Number | Description |
Tesla | 1064740-00-A | Adhesive Scraper Tool |
CAUTION
For Europe only: Only
technicians who have been trained in working with diisocyanates and have completed
all required certification courses are permitted to perform procedures using
urethane and other products containing diisocyanates. Proper personal protective
equipment (PPE) must be worn when working with products containing diisocyanates.
Removal
-
Make sure that the vehicle is on
a flat, stable surface.
NoteThe vehicle cannot be on a lift during this procedure.
- Make sure that all tires are inflated to their recommended pressures (refer to Tire Pressures.
- Make sure that the panoramic roof is fully closed, if equipped.
- Make sure that the power liftgate is operational, if equipped.
-
Protect all panels that are adjacent to the liftgate:
- C-Pillar body panel
- Fixed glass panel (with panoramic roof) / roof panel (without panoramic roof)
- Quarter panels
- Rear fascia
- Remove the upper liftgate finisher and the LH and RH side liftgate finishers (refer to procedure).
- Open all 4 windows. This prevents internal pressure from pushing out on the liftgate glass when it is installed.
-
Disconnect the harnesses (x2) that attach to the glass on the LH side of the
liftgate. Tape the harnesses to the liftgate so that they are out of the way when
the glass is removed in a later step.
CAUTIONTake care not to damage component(s).
-
Disconnect the harnesses (x2) that attach to the glass on the RH side of the
liftgate. Tape the harnesses to the liftgate so that they are out of the way when
the glass is removed in a later step.
CAUTIONTake care not to damage component(s).
-
Disconnect the harness that
attaches to the center high mounted stop light (CHMSL). Tape the wires out of the
way so that they are not damaged when the glass is removed in a later step.
-
Cover the floor and side carpet panels inside the trunk with plastic. This
prevents water damage in a later step.
WarningRead all documentation concerning the Equalizer Express360 tool before continuing this procedure.
-
Insert the cutting blade into the Equalizer Express360 tool.
CAUTIONOnly use the Equalizer Express360 to cut the 2 lines of urethane at the back of the liftgate glass (shown in green in the figure below). Do not use it to cut the urethane at the sides or bottom of the glass.
1 Do not cut to left of this red line. 2 Do not cut to right of this red line. CAUTIONWhile cutting, take care not to cut further than necessary to avoid damaging the liftgate or the rear roof panel.CAUTIONBefore and during cutting, use water or alcohol to lubricate the urethane. If any other materials are used for lubrication, fully clean the affected area before applying more urethane. -
Position the tool at a 45 degree angle along the rightmost edge of the top line
of urethane. Start cutting the urethane, moving the cutting tool from right to
left while an assistant continues to spray the soap and water solution to
lubricate the urethane.
WarningTo avoid personal injury, eye protection must be worn when performing this operation.CAUTIONDo not cut past the left red lines shown in the figure in the previous step.CAUTIONDo not damage the CHMSL while cutting the bottom line of urethane.
-
Repeat the previous step for the bottom line of urethane.
WarningBefore proceeding, read all documentation for the Equalizer Python rotating cut-out wire.
- Use the Equalizer Python tool to cut the urethane around the sides and bottom of the liftgate.
-
Secure suction cups onto the outside of the liftgate glass.
CAUTIONDo not rely solely on the suction cups when moving the liftgate glass. Ensure that the glass is supported from the bottom while moving.
-
Lift the glass off of the liftgate and set it gently onto a stand.
CAUTIONDo not damage the CHMSL or the antennas.
- Mark the location of the CHMSL onto the glass, and then remove and inspect it. If the CHMSL is damaged, replace it.
Installation
- Use the adhesive scraper to remove the excess urethane from the body.
- Temporarily reconnect the CHMSL to the harness in the center of the liftgate and have an assistant depress the brake pedal. Ensure that the CHMSL lights up properly. If any of the LEDs have been damaged, replace the CHMSL.
- Disconnect the CHMSL and secure it to the liftgate glass using double-sided tape (3M 06397 or equivalent).
- Close the liftgate.
-
Attach the spacers to the glass at the locations shown.
CAUTIONTo prevent degraded radio reception, ensure that the spacers do not contact any part of the antenna grid.
-
Apply primer as directed by the adhesive manufacturer.
NoteCheck the primer and adhesive packaging for the appropriate working times for each product. Prepare the necessary tools and work environment so that the the glass can be installed within the specified working times.NoteThis procedure requires approximately 2 tubes of urethane.
- Fully clean the urethane area.
-
Cut the applicator tip on the urethane tube to the appropriate size.
NoteCut a triangular cross-section into the applicator approximately 8 mm wide and 14 mm tall.
-
Apply the urethane to the liftgate glass. Be sure to follow the original
pattern.
CAUTIONTo prevent degraded radio reception, do not allow adhesive to contact the radio antenna grid. Ensure that the adhesive is far enough away from the lower edges of the antenna grid that it will not touch the grid once the glass is installed.
- Install the rear liftgate glass, making sure that the gaps between the glass and the liftgate are even front to back and side to side. Evenly and progressively press the glass onto the spacers.
-
Clean off any excess adhesive that was extruded from the joint.
WarningDo not drive the vehicle until the adhesive manufacturer’s recommended minimum drive-away time has passed. Dow Betaseal Express has a drive-away time of 1 hour minimum in temperatures of 0˚F (-18˚C) or warmer. If necessary, leave the tape applying pressure to the glass on the vehicle and advise the customer that they can remove it after 24 hours. Additionally, advise the customer that they should avoid high driving speeds and speed bumps for the next 24 hours.
- Reconnect all harness connections.
- Have an assistant use a hose to spray water along the edges of the liftgate glass. Ensure that no water leaks into the interior.
- Reinstall all components that were removed for access.
