Problem: AC only works through Defrost vents, need Help

all you need to do is trace the black and red vacuum hoses to the passenger side fender under the hood. They go to a vacuum resivor then to the solenoid. Make sure you have vacuum to the solenoid with the engine running if so the vacuum pump is ok and the solenoid is leaking. Either plug the vacuum feed to the solenoid or replace the solenoid.Mine went out twice and I just plugged it ... all works just dont have auto hubs

Same thing, you have a vacuum leak somewhere. I just tried swapping the vacuum pump on the top of the passenger side wheel well in my truck and it didn't fix it. I've been told to trace the vacuum lines down to the hubs, take them off and try cutting a 1/2" or so off and putting them back on. I haven't gotten to it yet, but will try that next and let you guys know if that works.
