Did you recently add Freon in your AC system? You might have too much Freon in the system, which caused the AC compressor to recycle more frequent than normal. Or you might not have enough Freon in the system. These BMW's are very AC system are very finicky. Get an AC gauge and check the level (high side & Low side) pressure.

I am having problem with the A/C on my 2000 BMW 323i. I just Changed the Compressor, Drier, Expansion valve. In march I changed all the lines high/low pressure lines and also changed the Drier as well....


The pressure sw. on the dryer maybe weak but the way you explain it I think the sys is low on Freon. The reason for this is you said it did not get that cold. I would add a half can or one to the sys and see if the compressor cycles longer. Hope this helps.

AC unit blows cold on passenger side and warm on driver side.


Hi,
There are separate blend doors for the passenger and driver's side. The blend doors divert, not block air, so it is unlikely that the blend doors are the problem. You need to check the operation of the re-circ door.
There may be some more duct work that attaches to the heat/air conditioning housing under the dash, that supplies air and or heat to both the driver side and passenger side of the car, the duct work on the driver side may have come disconnected.Check this also.
Hope this helps
Thanks
Smith.

2002 dodge caravan 3.3 liter v6 ac blowing warm. Refrigent appears ok. have it on 30 psi running. replaced clutch fuse. relay fuse ok. passenger side and rear blows less warm than driver side. Believe...


I assume you are charging this unit with cans from aparts store. If so the guages sold in those kits are not the best. That said I believe you are still low on refrigerant. Wear saftey glasses while working on A/C systems, and follow all saftey instructions. Then with a helper inside vehicle, run engine at appx. 2000 rpm. add refrigerant untill pressure stays at 35 psi with both blowers on high.

Hi, my husband and i have a 2006 optima. te ac


Absolutely not!  Never attempt to recharge from the high side. Recharging from the high side is extremely dangerous and could do harm to both you and the car.  If the low side pressure is only 10psi, you are low on refrigerant.  Most cars require 20psi to operate the compressor and should never fill to more than 40-45psi unless recommended by the manufacturer.  I'd re-check the pressure readings.  It's possible that instead of charging the system, while hooking up the hose, you've let freon escape, accounting for the hissing noise and the low pressure reading.  When recharging the AC system, it's important to have the car running and have the AC on high.  It's possible, you didn't have a good connection to the low side which also would account for the escaping refrigerant.  I hope this answers your question.  I'd try to recharge the system again on the low side, making sure the connection is good both at the low side valve and on the can of refrigerant.  Best of luck.

Ac blows cool only on drivers side of 2000 bmw 323i"


sounds like you have a low refrigerant charge. your best bet is to recovery the refrigerant in the system with an a/c recovery machine and see if you have the proper fill level. most likely the system is very low.
