A/C vacuum lines

[tobyduck]

Got to thinking hard about how to fix this problem. The A/C is stuck on defrost, I've had a lot of suggestions and the switch is not bad lol, leave some comments please!!!

the white line doesnt have anything connected to it and pulls a vacuum, the black line is connected into the vacuum system.
This is under the dash and everything seems connected and the other three colors (red,blue, and yellow) are connected under the dash

i dont know where the white line goes

I don't know the colors but there should only be one line from the firewall to the switch and then there are lines to the "doors" to open and close them. Defroster only is the fail safe the system goes to when there is no vac to the system.
In the past I have had a problem with a shotgun shell falling into the defroster and holding the door open..
