I think the hoses are just drains used to eliminate the rain who enters the vent below the rear window
for your rear defogger, mine stops working regularly. Each time, I brush the fuse to make it work. (this device uses much current so the fuse seems to corrode quicker than the others. Oxydoreduction of humidity?? Remembering my last year chimestry classes) Stainless fuses should fix it.
But if your fuse is okay, check your switch. These ones are very easy to pull out for a test.
Are the '80 have the timed defogger or it's just an on/off switch?
