Could someone please help me with a power window problem on my 1990 Tbird, 2 door ?
The passenger side power window glass somehow came off the track mechanism.
The window slid down and I can see the up/down mechanism and it works fine, just looks like the window came out of what appears to be two plastic looking tabs/slots.

1. Is it possible to get the window back in those slots without taking the door panel off ? I have tried a few times with no luck.

2. Not sure why it came out of the tabs/slots , maybe the door rubbers got dry and it jammed and pulled the glass out. Just a stab in the dark. Any other reason why it would come out like that and does that mean I would have to buy new tabs ? They look ok from what little I can see with a flashlight.

3. If I have to pull the door panel off is there a trick to it ?
I tried taking a few screws out and slightly prying but I think there may be clips somewhere that I may to replace if I get nasty with it and they break but would like to try to save that hassle if they will pop off with a trick some of you more experienced guys might know.
Is there a trick to getting the panel off as well as the clips ??

Any help greatly appreciated.

thanks, Vanisle46
