suspect a control panel issue as this HVAC (heater, ventilation, Air conditioning ) system should be all electric... If you can pull the control panel out looking at the back of it will answer your question... are the cables or just wires..
In f150 truck there is a small vacum hose passenger side up by the windshield. It's a small hose check really good they dry rot and it will cause your vents to switch. Also if your box is bad. It's next to the battery
All the vents are connected, a vacuum controlled flap diverts the air to each area.
With that said I would say that either the vents are obstructed by something like a rat/mouse nest or that your vacuum controlled flap is stuck or does not have enough vacuum to move it.
A vacuum leak will sound like a constant hissing sound.
I have the same car and had the same problem. The inside air intake for the heater system is located above the passenger's feet. An empty plastic bag got sucked in there and kept the door from moving properly. I had to take off a few panels, then one on the vent. Once I removed the bag, no problem.
remove gas filler cap.listen at filler while someone turns key to start.you should hear pump 'hum'.if not,check inertia switch [crash switch] behind carpet on left side of trunk.if it 'hums'check fuel filter,it may be clogged.if pump makes no noise,it may require replacement.modern [plastic] fuel pumps will 'self destruct' if ran dry.gas tank must be removed to replace pump.
