Problem i just found on my new used 2004 envoy xl. the top of the liftgate is wide open. I dont know if there is an actuator or something in there or if there is a fuse for it. but it looks like it should close or something. any info on this would help out.View attachment 29433
2004 envoy Xl endgate?
- Thread starter dazingla
- Start date
The liftgate hinges at the top, and the latch is at the bottom, so I don't see how that can be anything but a trim piece that's become dislodged.
its not dislodged though. its flush against the glass and it seems like theres a second set of gears in there. I seen the exact same one and once u park it goes down. i got the guy to showcase it out for me.

Maybe the XL is different. I don't have one, but I thought it would have been discussed if it failed for others in my many years on three forums. Can you take more close-ups?

I had one, and afaik, it worked the same as the short truck's rear hatch.the roadie said:
It is a different shape, and I don't know why. They could have used the hatch off the short truck and just moved it farther back; however, I digress.
There should be two sets of hinges, one for the full door to open upward, and a set for the window glass to open. It will open upward as well.
There is a known history of the top trim piece coming lose and falling off; one type more than the other. I don't remember if the problem was more pronounced in the long trucks, or the short ones.

lol doors in perfect working order. no rust on anything but that mechanical part. and i fixed it . Its suppose to reclose after the liftgate is closed but it was stuck in the open position.
There is a TSB for this with step by step instructions on how to fix a loose CHMSL applique. Mine was about to come off the other day. So I removed the applique and then refurbished the entire thing. I had to remove and reapply all the 1 inch 3M double sided sticky tape. Talk about tedious. A little bit of denatured alcohol cleaned up the surfaces including the glass. GM makes a glass surface prep spray but I didn't use it. The 3M tape sticks really well to the glass.

Condition
Some customers may comment that the CHMSL applique is loose on the liftgate glass.
Cause
A poor bonding of the double-sided adhesive tape between the CHMSL applique and the liftgate glass may cause this condition.
Correction
Re-tape the CHSML applique to the liftgate glass using the following service procedure:
Open the liftgate glass.
Remove the screws that retain the applique to the liftgate glass.
Do not damage the applique or the liftgate glass when removing the applique from the liftgate glass.
With a flat-bladed tool, carefully remove the applique from the liftgate glass.
Remove the CHMSL harness grommet from the roof panel.
Disconnect the CHMSL harness connector.
Place a clean fender cover on a suitable working surface and place the applique on the fender cover.
Remove the old adhesive from the underside of the applique. (For Saab Only Remove the two screws from the CHMSL and remove the CHMSL from the applique. Remove all the ribs from the back side of the applique as seen in illustration above. Clean the applique and the CHMSL with Isopropyl Alcohol (rubbing alcohol), 3M(R) P/N 08984 or equivalent, and dry thoroughly using a clean low lint towel or towelette. Apply double-sided adhesive tape, 3M(R) P/N 06397 or equivalent to the CHMSL lens as seen in the illustration below and install the two screws and tighten).
Tighten
Tighten the two screws to 2.5 N.m (22 lb in).
Clean the application area of the CHMSL applique with Isopropyl Alcohol (rubbing alcohol), 3M(R) P/N 08984 or equivalent, and dry thoroughly using a clean low lint towel or towelette.
Apply double-sided adhesive tape, 3M(R) P/N 06397 or equivalent, to the underside of the CHMSL applique.
Remove the old adhesive from the liftgate glass.
The installation area of the liftgate glass must be clean and dry. Any airborne dust, oils, etc., may contaminate the glass or the applique adhesive, and reduce the bond of the tape.
DO NOT use commercial glass or surface cleaners. These may contain petroleum.
The glass surface temperature should be no lower than 21°C (70°F) and not exceed 38°C (100°F).
Clean the application area of the liftgate glass with Isopropyl Alcohol (rubbing alcohol), 3M(R) P/N 08984 or equivalent, and dry thoroughly using a clean low lint towel or towelette.
Apply adhesive promoter, P/N 12378555 (in Canada, use P/N 88901239), to the liftgate glass surface, completely wetting the applique application area.
Use a clean low lint towel or towelette and wipe the glass, only removing the excess adhesive promoter from the liftgate glass.
Do not wipe the glass dry.
Allow the liftgate glass to air dry completely.
The applique must be installed within 30 minutes following the use of the promoter.
Allow the adhesive promoter to remain on the glass surface for a minimum of 10 seconds.
Attach the CHMSL wire to the connector and install the grommet.
Slide the liftgate glass on the hinge pins to the left in order to allow clearance for the locating hooks.
Remove the protective liner from the tape on the applique.
Attach the locating hooks on the applique to the hinge pins.
Apply the applique to the liftgate glass.
With the heel of your hand, and starting from center of the applique and working outward towards each outer edge, apply even and consistent pressure insuring complete contact of the adhesive strip to the glass.
Install the screws that retain the applique to the liftgate glass.
Tighten
Tighten the screws to 5 N.m (44 lb in).
The vehicle must be kept dry and at 21°C (70°F) to 43°C (110°F) for no less than 4 hours to ensure proper adhesive cure time.
Clean the liftgate glass and applique area.

so i just got the service history and the tailgate Applique was actually serviced back in 05. the comments say Rear tailgate does not open all the way (binds) tech comment replace and refinish tailgate applique as per bulletin 04-08-66-017. but what i dont understand is why they would replace is wrong lol.
RayVoy said:Your question eludes meAre wondering why it was repaired and not replaced?
Wasnt a real question as i already repaired it myself. it seems like their version of repairing it was move it into a position so the liftgate opened freely instead of doing it correctly and putting back into place where it should of went
