Air only blows through top dash vents...

The vacumm ball is in the fenderwell on 4wd's and is hard to get to, its beside the airbox but inside the fender. On 2wd's the ball is below the alt and airbox in the engine compartment. If you open the glove box there are plstic pieces on both sides that keep the glovebox from swinging all the way down, if you push these in the glove box will swing down and you will see a vacuum plug with different colored hoses. If you look back towards the firewall you will see the actuator for the blend door. Its either electric or vacuum depending on the year of your truck. BTW if your truck is a 4wd the vacuum is shared with the 4wd system and could be a leak anywhere from the manifold to the heater control or the hubs on the front wheels, you will have to trace the lines.

I'll check it again, but is this fixable from the inside glove box or is this something that I have to do outside the truck? Like I said, I checked the back of the glove box and just can't seem to find any cracked wires, everything looks legit but I have no idea where the wires lead to to check them. There's very little space to move around and check things.

The vaccum hose you need to check goes TO the black sphere, under the hood.
They have a bad habit of getting broken, burnt, etc.
If that one is good (inspect its entire length) THEN you need to look at the one from the sphere to the glove compartment area.
The sphere itself could be cracked too.

I'll post pics of my findings shortly...

The link between the actuator and blend valve busted in my truck. There is a free fix but I am not certain that this is your problem. When mine was busted I had no temp control and my AC blew only hot air but Max AC worked fine as well as all my other vent controls. https://www.ranger-forums.com/forum2...blend+door+fix
However air seems to come out the defrost vents when the control is set to foot vents. Its not slowly seeking out but its not fully open. It is slightly less air than on the defrost/foot position.
Sorry if it was already stated but where is the valve/valves located that direct air through the vents? I only know where the Max AC valve is.

Update
Well I just went outside and took some pics of my findings...
Not exactly sure what's going on but it looks like something got melted... The red wire seems okay:
Please advise on how to fix this issue... I believe this might be why my A/C won't blow out of the vents besides the defrost...

Unless the vacuum reservoir is cracked or otherwise leaking just trim the burnt ends off the plastic lines. Splice in some rubber vacuum line between the two ends and you should be good to go.

Where is that burnt end supposed to plug into? The red wire looks secure and good still but that other rubber peace connected to the ball is burnt off and not sure where its supposed to go.

Not to thread jack but..... My vents, ac and such work just fine at idle, but randomly when i accelerate it stops blowing from the vents and sends 100% of the airflow to the defroster vents. It will keep it blowing in defrost until im leveled out for a good few seconds. What the heck could be causing this?
Oh and it isnt just if i am at WOT or anyhting, it is at random rpm acceleration. Sometimes when i dont even hit 3k it will stop until im back to crusing speed/rpm

Just to clarify, the blend door and blend door actuator (BDA) are temperature control mechansims and have nothing to do with air flow or direction.
Airflow (venting) is controlled entirely by vacuum on the Ranger. A leak in the vacuum control circuit may occur during acceleration (slow leak), at all times (large leak), or only when specific functions are selected (indicating a leak in that portion of the circuit).
