Mein Auto: BMW 323i, 2000
A/C issue Blowing warm, next time cool.

Hi there all,

I have been having a go around with my air conditioning in my 2000, 323i . I am driving and have the air temperature at 59 degrees with the fan blowing at the highest setting. It's 85 degrees outside and this thing is blowing warm air. I make a couple of stops and then later it's blowing cold air. Like I need a jacket cool air. We have been dealing with this issue since 2011. We are going back to the shop in the a.m. Any suggestions would be helpful. Here's a bit of our history as follows:

8/2011 A/C service Freon added.

6/2012 A/C service replaced compressor and receiver.

11/2012 A/C problem compressor replaced again(under warranty)- AC did not come down to 350 PSI. Was told A/C expansion valve was plugged up.

6/2013 A/C problem was the high pressure possible blockage from the A/C condenser . high pressure on a/c side is at 200-225 psi. Condenser replaced.

Without reading more than once, I'd say you're cruising for a new evaporator. Nasty job or expensive depending on which way you go.


See what it'll look like to get to the evap.

I think they replaced that already - "condenser."

Sounds like stuff keeps clogging it or you just keep getting leaks. You've replaced many of the typical culprits. It may just be low due to another leak. The warm air then ice cold leads me to believe your evaporator/condenser may be freezing over and then thawing. I'm no expert though.

I can't remember what the symptoms are for the little vent on the left side of the A/C control panel clogging. Could try vacuuming that out.

Condenser is coil up in front of the radiator.
Evaporator is the coil in the car that cools the air for your face.

Read up on how whole A/C system works. Really quite interesting.

Ahhh right. Forgot about the piece up front. I agree, it sounds like the evaporator.

A little rusty coming off vacation.....
