The lvl select door is vacuum operated. I'm not sure where the vacuum block is located on this year, but if u look in a manual it will help.
You should see the vacuum lines under the hood on the firewall. There is a black housing that they connect into. Replacing that housing should fix the problem unless you have a cracked Vacuum line. You can get a cheapy T shaped line at most parts stores.

There are heater doors on the heat blower box that direct the path of the heat. Apparently the heater door to the floor vents is stuck closed.
the middle vents only supply air from the ac unit using a separate in dash fan. the floor and defrost vents come only from the heater
Warm(er) air rises - if vents were high up there would be little circulation without fans.
Most likely a bad or disconnected vacuum hose to the defrost/floor selector in the heater ducting.
under the hood. on the passenger side. near the silver air conditioning can looking thing. you will see a black thing with 3 vacuum lines attached. this is what controls the heater vents.
Could be that your heater core is leaking May also have a plugged evaporator hole.
The a/c - heater controller is out...........
It is more then likely your heater core. is it fogging up in your vehicle?
It should blow through the floor vents. Modern vehicles generally use movable baffles in there HVAC systems, to direct air flow where the controls indicate. If the controls allow airflow to the floor, but nothing flows out, there is a malfunction between the control switch and the actuator that directs the flow.
on the floor on the floor
Yes vents can be in the floor instead of the wall.
smoky mist coming from the heater vents.
Any of the following can cause this......... 1. Bad a/c - heater controller.. 2. Bad a/c - heater controller inside door operation.. 3. Bad, broken or cracked vacuum line/lines..
Check the following.......... 1. Vacuum leak, broken vacuum line or disconnected vacuum line. 2. A/C - heater inside car door operation.. 3. A/C - heater controller..
It means you have a leaky heater core. You may also find the front passenger floor wet with engine coolant.
I think your refering to the door in the heater housing that directs air to vents, floor or defroster vents, there is also a blend actuator that mixes heated or cooled air to give the correct temperature from the selector.
if its not heater cole ...it could be water getting in from outside your car vents near the wipers clog up with leaves etc.
Leak in heater core. Replace core.
Your heater core is leaking, Need to REPLACE HEATER CORE.
Just heater outlets for the rear area. If you were to remove the console assembly which hides the engine cover, you would see a duct running from the top to beneath the floor. It feeds the vents you mentioned.
Check for vacuum leak or bad vacuum motor Check selector control
A vacuum leak, or one of the doors is sticking/bad vacuum motor in the heater box.
heater core needs replacement
AC VENTS are in the correct position if they are open and free flowing. Some systems have a heat and an AC position for the vents. The AC position is so the cool air discharges from the vents higher on the walls or from the dash rather than floor or windshield in a car.
