  1. E46 still battling lean codes after a year

    General E46 Forum
    Ok so still fighting my ‘01 330i on the dreaded p0171 and p0174. It seems as if I have gotten it down to something with the ac. Call me crazy. I haven’t read anything in any other thread about this. But it only throws lean codes when I’m running the ac system. Any guesses?
  2. Need help troubleshooting A/C Compressor problem

    General E46 Forum
    I drive a 2005 325XI. Air Condition is not working. I don't know much about cars, so I'll tell you what my mechanic told me. He said the car is not turning the compressor on. However, he said the compressor works when externally powered (apparently it's a 12V power), and it works when he...
  3. Air conditioner and the sun

    General E46 Forum
    Hi all. I have a 2002 330xi and have had an intermittent issue with my air conditioning system for a while now. The system works fine most of the time, but when I park the car in the sun on a warm day the air conditioner starts and blows very hot air out all the vents and the air never cools...
  4. AC linked ventilator problem

    General E46 Forum
    Hi guys, I have a 330ci and yesterday I removed 11.5 kgs of rubbish out of the engine bay. This included all 4 ac hoses, ac compressor and it's mounting frame, ac belt and some ac tank from behind the fender and the ac belt. The reason for that was that I never use ac, little weight saving in...
  5. 2007 525i a/c problems

    General BMW Model Discussion
    I have a 2007 BMW 525i with air condition problems. The car was blowing cold air depending on the outside temperature. Cold air on cold days and hot on hot days. now, it is consistently hot. My mechanic claims it's the compressor. he says it turns on and it has Freon. In the past, the...
  6. A/C issues; blows warm, can't modulate

    General E46 Forum
    I've searched around a bit for answers. Haven't found anything yet. Here are the symptoms: Blows warm about 50% of the time. Unresponsive to thermostat setting. It doesn't matter how I modulate the fan power, it either blows full blast or not at all. I.e., even if the fan is set to the...
  7. Air conditioning blows warm / cold intermittently.

    General E46 Forum
    The A/C on my '01 325xi wagon is acting up. Sometimes it won't blow cold air and then I will hear the A/C engage, make that very faint hissing sound and begin to blow cold air. Then randomly it will stop blowing cold again. If I turn off the AC button then turn it back on, sometimes that will...
  8. Blower motor won't spin inside car, but will out side of car.

    General E46 Forum
    The ac went out in my brothers 330i, the fan would not turn on at all. We change the FSR and tryed again but nothing happened. So we took it to an shop and they said the blower motor was bad. We took the motor out and checked the motor with a battery charger and it spun. we put it back in the...
  9. A/c

    General E46 Forum
    Before I head over to the nearest Auto Part store, I would like your opinion guys. Currently I own a 2002 325i which is currently having issues blowing cold air. I believe it started when the underside of my car got destroyed due to a unexpected dip (will post a pic later) but here is an...
  10. Air Conditioning problem

    General E46 Forum
    For a while I my 325i's AC would stop working at random times, but it would come back on 10-15 minutes later. The AC light turns on, as well as the fan, but nothing blows out of the vents. However, this would only happen every now and a again (once every few months). Yesterday, I went to turn...
  11. Noise from the center vents

    General E46 Forum
    My 323i is blowing HOT air from the center vents and after about 5 minutes the air finally begins to turn cold. It is in the 90s outside. Needless to say this is very annoying. I have replaced the hot water valve. The 134a refrigerant is cooling well once the vents quit pouring out the heat...
