I had this asked several years ago, and got nowhere with repairs on it. Revisited site today, found this:
2g window adjustment
And it sill does not help.
We have 95 2 door Eclipse GS.
Driver side glass flops in the door back and for, making loud rattle when door is shut. I need to sell the car, and it's one of the most obvious problems with it. You can grab top of the glass and move it side to side about an inch almost.
Last time I was advised to remove panel and work on some adjustment brackets that control the glass. I did, but they apparently work only one way - towards the outside, so we secured the glass, but ended with a large gap between the door seal and glass, on the top, with door shut, so I had to bring it back to sloppy state, but no rain getting in. The door does not have full window frame, it seals against the body. Just like you would have in a convertible.
I shall most appreciate practical advice on how to prevent that glass from rattling. So far, it looks like it needs to be pulled TOWARDS the inside.
Thanks you in advance.
