On my 76 280C, my rear passenger window went down...

[Tomas7]

....but it went down crooked making a couple of noises on the way.
It does come back up though.
Any ideas?

Thanks in advance.

seen in electrical diagram says theres a fuse behind rear seat pass side did pull rear seat wasn't a fuse just a box with 2 wires wonder if this is a strip fuse

[Tomas7]

So............my rear passenger glass came unglued or unhinged from the rail. WTF?
There's nothing holding the glass! It's just sitting there held in place by a rubber long bushing of some sort.
I took my panel, etc. off only to find that there's an opera hole where by we can work on the glass, rail, etc. I applied silicone sealant/adhesive in hopes that the window will seal better and stay.

[Tomas7]

Well the silicone glue/sealant/adhesive did not work.
Do I need a new glass that has the rail glued to it or is there another method?
Do I remove everything and try some other type glue?
Does the rubber bushing around the glass need replacing?
Thanks in advance.

There are a number of possibilities which could be the problem.

A: You could be correct in the rubber insert's failure.
B: The urethane sealant might have lost its adhesion.
C: The metal frame holding the window rail to the glass has split.

To solve A & B take the car to a automotive glass replacement shop. They will have the rubber strip and adhesive. 3M makes the correct adhesive. It is a urethane/epoxy which will "stick" to the glass.

For C you will either need to source a new rail or repair the one you have. If it is split, any competent welding shop can braze it.

Thank you very much Mike D

I finally took the window apart yesterday afternoon. Yes my window rail is split at the bottom towards the front. Nevertheless I took everything apart and cleaned and applied tons of Ace Hardware glue that supposedly adheres to glass. I let it seat for over 24 hours. The window is working fine. I am still going to source me a rail and new rubber insert.
Thank you once again.
