SOURCE: my ac only blows from defrost and floor

Look for vacuum leaks. System is designed to fail in defrost mode. so.... vac hose off, for example, would cause an issue like you describe.

How do I confirm a blend door / actuator problem?


blend door concerns heat and cold air ducting flapper. whether electronic or manual truning of a knob there is a movement noise. a motor/s make/s a sound on electronic controlled ones or a turn knob harder at times to turn does this. then feel the changes hot/cold breeze and no breeze etc..on the vent according to what you turn the system on to do. it is best to confirm movement /motion of the internal motor or flapper during night time or early morning in the garage inside the car devoid of noise to hear the motor or flapping movement, must hear some motor effort or feel hand effort if cable to the heater valve is intact/ not snapped to open heater valves on the engine side. then inspect heater cable if heater is not working etc..hope this helps.

Rear Floor Vent heat only


Sounds like your heater coolant hose door flap is broken or loose. May want to check behind the heater controls, if your components are mechanically operated. If electronically, may need to perform more troubleshooting before replacing this component.

Left Vents blow warm/hot air when calling for cold air


Usually a sign of a faulty blend door under the dash.
The blend doors direct air thru the ac and heater core along with the upper and lower vents.

My AC works but heater blows cold on my 99 Plymouth voyager


I used to install AC in those, so I might be able to help. It is either the temp adjustment linkage, or it is the accessory selector. When you go from AC to heater does the air move from the vents to blowing on the floor? If so then it is possible that the linkage to the temp controller has probably slipped off one of the levers that controls the incoming air, from cold to hot. It is an easy fix. It would have to be that, because if you couldn't switch from AC to heat, you can always make the AC hot with the temp control lever.

Check your ducting and hoses going to the left side. Maybe one came loose.
