Heat only coming out of passenger two vents all the time when any system is on. Driver side get's a vent, heat and AC. When Ac is on only very hot heat comes out on passenger side. Dual climate control on passenger side is off, any suggestions? @ mechanics can't find the problem!
The actuator door that is behind the dash that closes off the heater core from shooting hot air thru the vents might be your problem. When you turn on your ac the actuator shuts the door to prevent the air from flowing thru the heater core into the cabin, this may be your problem if everything else is working properly. Let us know.
SOURCE: dual heat and ac system
broken cable? if possible trace the cables back to the box move then bolth and see if one doesnt, if so you could alwase manually move it for a temp fix

I have seen this before. There is a vaccume controlled panel that opens or closes depending on the dash setting. In your car there are 2 seperate control panels,one for the passenger and one for the driver. There could be a loose or broken vaccume line on the passenger side control panel. It should be located behind the front passenger kick panel on the right side foward of the door. Sometimes you can here the leak. Sometimes if the leak is bad enough you have engine idle problems. It can also be the door itself. Sometimes the control linkage on the door breaks. It can be difficult to access these areas. A maintenance manuel for the car will be helpful. Good luck!
SOURCE: Heater, defroster and vents blow cold out of
flapper doors inside duct blocked or not actuating
NO HEAT ON FLOOR VENTS
