Being a 2006 BMW, I don't know if you really want to tear into the dash compartment. Your AC is working fine, the problem with the unit is your heater control valve under the dash is faulty. you cant fix it but replace it the cost with single solenoid 85 bucks and dual solenoid is 172 buck; your would have two because your car equip with his and hers climate control; without proper tools to work on the car taking the dash apart is a task especially you have to know every bolt location. The unit is not adjusting the valve like it suppose to. The valve work like and normal valve, same as your faucet at home on or off. the valve is not shutting off fully due to solenoid faulty or the valve it self is stuck,jam or not sealing and that is the reason why you still getting warm air. I can assure you if you turn the ac button off and let the fan run only you will get nothing but hot air, the air seem warm because is mixing with with the cold air from your evaporator. hope that help some, good luck

There is a divert valve to control a flap directing air thru either heater coil or Evaporator depending on when you select heater or AC . Either the cable holding the Flap or the valve is not working. Need to check this out- a lot of work through behind the center vent. Good luck

Why am I getting cool air conditioned air out of drivers side, and hot air out of passenger side (want cool ac on passenger side also).


There are 2possibles ,1. The heat / cool slide control is defective, it is not possible to repair. Most likely the servo motor that opens and closes the air vent that gives you heat or cool is stuck. Open your glove box and you will see 2 rubber tabs that hold the door at the open and down position. Push down on your glove box door until it swings all the way down (this wil be past normal open) up inside you will see a metal rod affixed to a arm that pivots via the servo left is full vent(cool) right is full heat. Push your hot/cold heat selector and see if it moves. It may not be moving its full extension. If your not sure push it right and you should get heat push it left and you should get cool check YouTube this is a common problem for this era of Buicks, good luck Bret

you will have to inspect the blend doors. These are the ones that control the flow of the air in the AC duct. It is under the dashboard. There might be loose linkages or parts that you may just need fitting or a bad motor for the door.

Hi bensarabia,

This condition is usually an indication that the a/c refrigerant level is low. The driver's side will always get heating and cooling first. I would recommend having the refrigerant level checked and also having it leak tested.

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

That is correct...How to correct it will take some disassembly if you can follow instructions and sorta good with tools and have some nerve then get a Bently Service Manual on your BMW... It will be the best 100.00 you spend on the car, If you are frugal then look for a used copy on E-Bay.....
