77 CJ5 defrost duct

The duct is crumbling behind the dash. It looks as if it's made out of some sort of heavy cardboard. Where can I find a replacement and how hard are they to install?

Are you looking for the actual duct or the corrigated connecting hose?

On the 1977 and below CJ's the actual accordian style duct hose is longer then the 1978- up Cj's. I don't think the one mentioned above will not be long enough.

Try not to rip/tear . When I was looking for a new one I could not find it anywhere and heard they are not being made in the aftermarket.

CJ5_Fan; I found the crumbling cardboard when I replaced an after market temp gauge installed in the dash. The gauge is mounted about 6" to the right of the original instrument cluster. When I removed the old gauge I could see a 3" hole in the cardboard like material, I turned the defrost fan on and air was rushing through the hole.

looking through a 2-3/8" hole in the dash It didn't resemble the one in your link.

ahhh - gotcha now... I think you need the old style heater that had ducting that ran a seperate hose behind the dash.

look here:

If that is not it, then check with these folks and maybe they can help you find it.

BTW - crumbling cardboard on the right side of the dash may be part of your old glove box, they were made of cardboard back then.
