AC control vacuum lines

[Sgt Gus]

Ok, looking for this tiny vacuum line. Not local or with LMC?
It was brittle where it went through firewall.
I can slways splice if I can get more line.

They usually sell it at the parts store in two sizes - GM hard vacuum line. You can splice it with small sections of rubber vacuum line.
Dorman 47419 or 47417. https://shop.advanceautoparts.com/p...c0b18210d9ac1e105db3e4328e043715&gclsrc=3p.ds

I just took a piece to my local napa, and got rubber vacuum tubing that fit the outside diameter. Has been working great for years.

Interesting- your blower seems to have 3 speeds. Goldie (1980) has 4. Wonder when they changed ?

It's four, zoom in. I think either the low or high didn't work. Looks like we can order that switch, if that is the problem.
