    Purge solenoid & AC, not related, unless it's "T" 'd into same vacuum line, as your source. Do you have the control panel out of the dash yet?

Does your control panel have cables working some of the doors below in duct work. Can you see any cables up under passenger side or drivers side. Those lines I think your talking about, will only get vacuum as needed to move an actuator(vacuum motor) , so I'm guessing that if the control isn't in the right position, then it won't route vacuum to that particular line. I have msn , but I never set up an account, it's just used by my kids, sorry. I always figured I type too slow to have a conversation on there, but maybe I'll consider it soon.

    There is normally a main vacuum feed line that goes into your control at back, then the control re-routes it from there to whatever part needs to move for what mode you have control in. if you get control panel out, which is pretty easy on that I think, you'll be able to determine which line is your feed (incoming vacuum source) then you can go from there, to check vacuum coming out of the control, and to doors etc in ductwork that should move when it's appropriate.

Ac vacuum

There could be a vac tank problem or a vac leak.
Most american vehicles use a plastic ball or object as a vac holding tank. The tank or a vac hose can be leaking.
If the system fails, the default position is the defrosters for safety.

AC blowing through defrost vents only. What could be causing this?

either no vacuum is getting to the vent door switch or the vent door switch is bad, but I suspect the vac hose is diconnected, or cracked. under the hood the line goes into the dash to work the doors, make sure its got vacuum to it when engine is running., or there is a vac leak

Inside fan stops blowing when accelerating. esp when ac is on.

Check the vacuum line from the engine that feeds into your AC/Heater controls. If it is cracked, broken, or collapses under vacuum, then replace it.

Ac vent problem

the vacuum canister is located under the battery tray on this model truck, however the most common problem are the vacuum lines that run around the battery box. usually the battry will leak acid at some point in time and create holes in the small hard plastic lines. i would remove the battery and check the vacuum lines first.

I’m happy to assist further over the phone at
