Hey guys,
I have a white '04 Envoy, And the seal that goes around the "liscence plate panel" on the rear hatch is black and really stands out! I've seen a couple of Trailblazers and Envoys without it. If I take mine off, will it leak water into my SUV? Do you think it would be safe to do?

I have had mine replaced once, and getting ready to have it replaced again. Not really sure if it needs to be there or not though.

Why did you have it replaced? I noticed on mine that it looks like he seal is coming out in a couple of places. Anybody of you other guys have problems with this?

I had it replaced because it was sucked in almost halfway around the thing. Basically it just looked horrible. Not sure if it was actually leaking anything or not. I will have to ask when I get it replaced again.

License plate panel gasket

So far at two years and 15K miles on the '03 Envoy my gasket is still okay. It does spend quite a bit of time in the garage. Could this problem be weather related? Too much sun or ??

Hey guys,
Thanks for all of the info, I was just curious if the gasket was needed because my Envoy is white and that gasket really stands out! I just wanted to know if I could remove it. Thanks again!

Don't remove the gasket!

Here's the deal with the gasket around the license plate frame: if you remove it, then the license plate frame will rub the paint off the tailgate!

I have a really, really early Trailblazer. It's a 2002 that I bought in July 2001. Back then, they didn't come with the frame gasket. When I took the car out in the morning, and the sun hit the backend, the tailgate would pop and crack. That was the metal and plastic expanding at different rates. Within about a month, all of the paint around the edge of the license plate frame had rubbed off. So, the dealer repainted it, and then re-seated the plate frame. Two months later, same thing. All of the paint was gone. By then, GM had figured out the problem and had added the gasket to all of the new models and put out instructions to fix the old one. So, the dealer repainted again, and added the gasket. No more paint problems and no more popping and cracking.

Since then, I had the dealer re-seat the gasket 3 times. It kept on getting "sucked under" the frame after a few months. This didn't cause any problems, it just looked bad. I eventually went to another dealer who properly seated it and it's been okay for the past two years.

I know this is late, but I hope this helps someone. I'd hate to see someone else get the paint scraped off the tailgate.

License Plate Gasket - Need Repair Procedure

The gasket getting sucked behind the license plate piece is a VERY common problem for Trailblazers/Envoys.... (Note the 3 pages of discussion over at Automotive Forums: http://www.automotiveforums.com/vbulletin/showthread.php?t=272392&highlight=license+plate+gasket)

I have an '03 Trailblazer and it has been replaced 3x. Since my warranty is about to expire, could someone post a repair proceedure in the Technical Articles section on how to replace myself?

Thanks in advance and great forum!!

Mine isn't pulling in, it is "leaking" out. When the sun hit it on hot summer days it would almost drip out, at the end of the day I would find small balls that I could rub off.

FWIW, the gasket reacts to the dissimilar properties of the plastic and the metal. Since the metal is in the larger outer piece, it will heat up faster than the plastic insert where the plate is mounted. The temp. disparities (sp) will either draw the gasket in or push it out. According to a buddy of mine, there is no real fix , just keep replacing the gasket as needed. :m2: :yes:

Please take some pics, as Im still not exactly if I have the gasket or not. If I dont, I will pull it apart and see if it is rubbing, but I havent had any paint chips yet.

OK, did the deed today.
First step is to take off the paneling. Open the glass. to the left of the lock there is a black push pin. take that out. close the glass and open the tailgate.
yank off the top part of the paneling. it just pops out. Then remove the strap using a Torx driver. mine REFUSED to come out and I stripped it. I was pissed so I took a vice grip to it and busted it off. Good luck with this.

The rest of the panel just pops off.

Remove 7 nuts circled (and pointed to) in the picture. Unplug the license plate light.

Disconnect the tailgate handle from the popping mechanism as shown. Push the plastic part a little and it should be loose. Go outside your car and pull it out.

Put the rubber U seal around the edge of the plastic piece. trim any excess. Push hard against the plastic to make contact (there is gooey black stuff inside the U channel). You may want to touch up any scratched paint around the edge of the tailgate if you had this problem. Don't worry about making it perfect as the rubber seal will cover it.

Whammy! Reinstall whatever you took out and enjoy!
