What causes the crack on the passengers side door trim?

[sidonsbones]

I have a 99 Trans Am WS6, but I think this is an issue with a lot of F-bodies. The interior door panel has a crack that appears at the top towards the rear. I've looked around for the panel, only to find others that are cracked in the same location. What is happening here?

Not just the passenger side, ...

Don't really know the answer yer lookin' for tho.

my drivers door has this also. i to dont have an answer for you.

[02 Blk T/A WS6]

both my doors did this on my ta.
my service guy claims its from the cold.then when i cut the heat on the quick change in panel temp weaken them and eventually they crack. atleast thats what i was told and they were both changed for free.

so i didnt complain or question it

both mine are like that as well. i dont think it really has much to do with the temperature as much as it does with the window torque when you roll it up and down. ive noticed when my window is traveling up or down it either pulls or pushes the door skin in or out... i think that might actually have a bit more to do with it than the temp... but not for sure...

Same problem here on the drivers side. Do any of you think that new weather stripping would help? Thanks, Keith

Well, I feel better about it now that I know I wasn't imagining the problem. Another problem I'm noticing is the seat belt guide on the head rest. I broke mine getting out of the car recently, and remembered this happened a lot on the second generation f-bodies as well. I'm thinking of milling a new piece out of aluminum.

Exactly, it's the flex of the door panel from the window in the fully down position.
My '00 has both sides cracked about 1/2" or so.

DING DING !!!!!!!!!!!!!!!!!!!!!A winner, it's a combo
of the power window motor and heat. The door panel will actually
'Torque'. this is not a good thing.

[calb80]

is there by chance anyway to keep this from happening if say the door panels were replaced or is it inevitable??? does anybody know?

[227HAWK]

If replacing the door panels =Remove the 4th staple from the front of the panel.
Then super glue the holes.

Same thing is happening to mine, looks like poor design along with the window and the heat thing. Seems like something is putting a lot of stress on that same area and it just starts to crack, maybe not enough door clips or something.

Isn't the paint warrantied for like 5 years or something for rust?? So why isn't there some kind of extended warranty for workmanship on interior parts? My ws6 looks new with only 22,000 miles on it. But yet I have a small crack where the window molding is like you guys. The crack is so small nobody else would notice. But I'm worried about it getting worse or spreading!!!

[sidonsbones]

The one's I've seen (and the one I have) are about an inch, or inch and a half. I've seen several in the junkyard this way. Probably isn't a lot you can do about it though.

Unfortunately it will get worse.
Mine started out the same way with just a small hairline crack. Now it has gone almost all the way down to the door panel insert. I have a bad feeling that new door panels are EXPENSIVE! No I haven't priced one yet but knowing GM.......

[02 Blk T/A WS6]

not sure if there expensive but i do know that you might have to wait awhile to get them.

when i had my replaced for free they had a passanger side in stock but they couldnt find a driver side one and i was told i had to wait till gm made some more so it took me 2 months to get the driver one, which sucked but i cant complain too much as i didnt have to pay for them at all

MY 02, THAT I BOUGHT NEW, HAD BOTH PANELS CRACK. LIVING IN NEW YORK I WOULD PARK AND STORE THE CAR THROUGH THE WINTER. LAST YEAR I PARKED THE CAR UP ON BLOCKS IN THE COLD WITH NO DAMAGE. WHEN I PULLED THE COVER 3 MONTHS LATER, GET IN THE CAR AND BOTH PANELS ARE CRACKED. CAR ONLY HAD 7K ON IT. STAY LIKE NEW IN UNHEATED GARAGED NEVER TOUCHED, WRAPPED UP IN A COVER. DEALERSHIP REPLACED BOTH FOR FREE BUT GAVE ME NO EXPLANATION.

Cheap ass parts and the door flex from the window motors is what cracks them. Pieces of shit.

I wonder.....do the Camaros have the same problem with their door panels?--Tony
