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.

Why does 1 side of dash blow hot and the other cold when ac is on with the dual climate control?


Check the actuator motor on the heater it directs the air into the vents. There is probably two of them be sure to check both. The motor makes the vents move and again directs the air where you want. Hope this helps.

Why does My thermostat Not switch between ac,heat,defrost . there's cold air coming out of vents but not cold enough to be ac. Initially when this started the ac was blowing hot air


If the air flow cannot be controlled from vent/defrost/floor you may have a blend door issue. This is an electric motor that operates a door in the heating system to control airflow. There are usually 3 motors controlling airflow direction,heat and recirculation. The Ac not blowing cold may also be another problem. If the AC is operational, the compressor will be engaged and the Ac low pressure line under the hood will bw cold. If this is all ok then a blend door issue should be suspected

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.

Ac blows hot air ac compressor is ice cold but the vents blow hot air when enige is hot. bloows cold air when engine is cold


check your air diverter doors, sounds like the door for heat is open, when a/c is selected the doors should move and close the heater off. the heater will over power the a/c. the door controller is located on the environmental station under the dash neat to the floor. the control is electronic and probably not functioning
