Sounds like the blend door is not closing all the way to seal off the heater core. Locate the plenum and the levers that are on it. Check to see which one is for MODE and which is Blend. Make sure they are not broken or loose. Also something that falls in the defrost vents can end up in the plenum and cause problems.

325i 2001 bmw, only one side from vents ac is working flowing cold air, driver side only, passenger side is only like warm air?


had same problem with my 01 325ci ..... talked to several bmw independent technicians and found out that the evaporation coils run across the dash from driver side to passenger side. If you get low on freon, then the driver side will continue to cool down, but the passenger side will gradually stop cooling or blow warm air. Solution ,is to check for leaks in AC and then recharge the system w/freon .... unfortunately , with my car intead of a 150.00 bill for a AC coolant recharge from normnal wear

Driver air cool, passenger air warm or hot


Are you sure you checked the temp door ?Is it hot air ,like the heater?First check the ac compressor to see if it is actually turning,then check the large ac lines near the firewall near the windshield to see if they are cold,and sweating.If they are that rules out freon problem.The temp door might not be moving,check all selections on ac control and watch is door and see if one of them doesn`t move.If one door doesn`t move then it is the one you need to fix,if I can help,let me know.roniecon@gmail.com

2006 Honda Odyssey Hot Air on driver side, cool air on pass. side


The only thing I can think of other than the AC control unit being bad is the small tube under the drivers right knee. If you look down at your right knee you will see a small area that is vented. There is a hose hooked to this vent that pulls air from inside the cabin to tell the ac what the temp is. If this hose is off or pinched the ac unit is not getting the information it needs in order to run correctly. Hope this helps.

My lesabre blows warm air on driver side cool air on passenger side


If you have dual climate control, you most likely have a low freon level. The evaporator can get cold enough for the passenger side (where the evaporator is located), but not cold enough to transfer cold air to the passenger side. Have it inspected for a leak and the freon level topped off.

AC blows cool air on passenger side but warm on driver's


Yes there is both a door and a flapper you have a problem with a blend door motor, it is not switching to cold it is half open and half closed so you need to replace the motor vacuum motor it is under the dash near the heater on the passenger side and if it is the other motor under dash you will have to take part of the dash apart to get to it, to test buy a piece of vacuum hose 1/8 inch diameter about 3 feet long and you can hook it to each of the vacuum motors and **** on the end of the line to see which one is causing you the problem, also could be the control head for the AC inside the car where the controls are, you have to remove the ac cluster ot get to the vacuum switch it's all vacuum operated and if you pull it out you will be able to here an audible sound of air leaking if it's the switch.

Cool air only coming out on the passenger side


sound like you have a diverter valve some where in the unit that is not switching the air flow as it should. sometimes just playing with the controls back and forth may free it up. If not then you will have to go into the vent system and find the valve that switches that function. Good Luck
