The mode door is vacuum controlled in the GC and the default fail position is defrost only. You most likely have either a vacuum leak or a broken vacuum line. There is a vacuum junction under the passenger side dash that kids like to kick and pull the vacuum line loose. That's the first place to check.

Why would the ac on a 2000 Malibu always blow on your feet no matter how you set it except for defrost then it blows on the windshield?
Either you have a defective selector switch or the most likely is that you have a broken,cracked,or loose vacuum hose at the rear of the engine.

Check the Escapes blend door system. The door is not working properly and causing all air to go to the defrost.

How to fix Jeep Cherokee heater control valve?
Fixing the heater contol valve is very simple, however, what i might say could be totally different than what you need. I have a 1987 Jeep Cherokee Pioneer 4.0 and my heater control valve went bad and started leaking coolant like crazy. This is a very common problem with these older Jeeps. luckily, it's an easy fix. What you have to do is go to your local parts store (Schuck's/Checker/Krager, Napa, Auto Zone, O'Reilly, whatever) and ask for a heater control valve for your application (year, make, model). then it's just a matter of locating the valve (between the coolant reservoir and heater core) undoing a couple hose clamps, taking out the old one and putting in the new one. very simple. I hope this was helpful.
Why is it on a 1997 ford f'150 only hot air no matter what the controls are set on and only air out of the defrost?
Check the blend door under the dash on the F150. Check the vacuum system as well. The vacuum controls the blend door and controls the heat as well as air from the defrost.
1995 Dodge Ram heat is lukewarm?
the most common thing this time of year is the thermostat. it may be stuck open or be too hot of a thermostat. i use a 195 degree in summer then put in a 180 in the winter. also check the heater core and housing. the heater core may be bad or clogged or maybe the housing is full of debree this happens in areas that are heavy in falling leaves. also it could be a matter that you are low on antifreeze. finally i would check the cable to the heat selector on the dash. it is common for them to beak in the plastic cover. to check this see if you can move the butterfly valve that supplies the heater core by hand. hope this helps.
