replacing back window

[mark sr]

My 2010 jk has a tear in the back window and my grandson gave me a new one [master top]

Are there any tricks to unzipping the old one? It hasn't been completely unzipped in over a dozen yrs. I can get it most of the way up the side but then nothing. I've been spraying the zipper with a kitchen cleaner but it hasn't seemed to help.

I use this stuff and like it

I've heard of people rubbing chapstick on the zippers.

I've found that everything with a softop is easier if they are warm. Try parking it in the garage if that's an option.

Be careful if you try to use pliers on the zipper - I always end up breaking them that way.

Yeah. Best done in the sun and the 70s or higher. Let the plastic stretch. Clean old teeth with toothbrush and soapy water. Nothing harsh.
To lubricate you could:
Rub a bar of soap on the teeth.
Rub candle wax on the teeth.

Check the zipper. If the isn’t meshing the teeth the back of the zipper may be spread or worn.
Caution if you pinch the back. These are weak and crack easily.

I bought new at some point before replacing the entire soft top
