New owner, old truck, help needed with climate control

My AC is charged, used to work great, but temp lever seems to have no effect on air temp coming from vents. Lever slides very easily. Does anyone here know if this is a servo operated lever, vacuum, or mechanical?

Since you said " lever" I assume it is a manual system ( 3 levers, temp, mode and recirculate) it is a cable system. The most likely problem is any one or more of the following.
cable retaining clip broke/came off and cable is loose
control head ( the place in the dash that has the levers) has a missing clip, or the lever mechanism is broken.
temp door is stuck or blocked, and caused cable to come off
the doors should move freely without much force, if there is resistance then it will cause the cables/ levers to break, this goes for all 3 doors.
My rule of thumb is remove the cable from the door in question and move it by hand to check for restriction or being stuck, if it seems okay remove the control head ( caution, do not pull it out very far if you havenot disconnected all cables from their door) If control head and cables are good, reinstall everything, if happens again replace the control head

it is a manual system. if the cable has broken, or come off of the temp door it will cause this. i will try to answer the best i can
