Default Vacuum lines behind climate control/radio

Am in the process of replacing the aftermarket radio in my 85. Noticed that I have 3 vacuum lines that a mouse chewed in a few places. They are RED, PINK and LIGHT BLUE. All of them are chewed to the point I can't identify where they went. If anyone has insight I would appreciate it. I'm guessing some or all are part of the climate control, but wanted to research a little more before I start disassembling the dash any further.

Thanks!

Those are the lines for your HVAC vent controls.

Thanks for the info. Makes sense, the climate control has never worked like it should. Now I just have to figure out how to repair or replace them all.
Do you think splicing them would work? If I could find a rubber hose that fit snuggly over them would it work, or is the vacuum pressure high enough that the lines need to be 1 piece?

No need to tare into things to deep unless really chewed out of sight. cut off clean slide a piece of proper size hose over and bridge/splice damaged parts.

Thanks S Carter, that was what I was thinking but didn't know if the connection would be tight enough to seal
Going to give it a try and see what happens
