  1. climate control vents stopped working

    General E46 Forum
    hi. I have a 04 touring. everything worked as normal before i removewd the dash. I removed it because I needed to find a coin that the previous owner lost in the vents. when the dash was removed I manually pushed the flaps on the top of the climate control box. this turned out to be a bad idea...
  2. Air conditioning with an aftermarket fan and controller

    General E46 Forum
    Some information to start. I have a 2002 330CI. I began having some cooling issues so I decided to beef up the system a little bit. An aluminum radiator and flexalite controller later, I begin to have AC issues. The blower will run but no cold air will begin flowing. The FSR is new, fuses and...
  3. 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...
  4. Part number for plastic spacers on A/C hoses?

    General E46 Forum
    Hi, was wondering if there's a part number for the little plastic spacers that are on most of the A/C pressure hoses. I'm replacing the whole system, and most of them were so brittle that they snapped off when pulling the hoses out. Here's a pic of what I mean (it's the yellow plastic spacer...
  5. No interior airflow; blower, fsr, auc checked.

    General E46 Forum
    I'm a new member, DIY'er and first-time poster. I have a 2004 325i sedan. Last week on a hot day, I heard a faint whine from what seemed like the blower. The sound was high, centered and deep in the dash, but a low-pitch whine, worse at higher blower speeds. I suspected bearings would be...
  6. A/C troubles continue

    General E46 Forum
    I have a 99 328i and my a/c is not working. Compressor is working, pressure is good, evaporation valve replaced. , the system worked for a few minutes today until a cloud of what I suppose was the r134a coming near the passenger side of the firewall. I'm at a loss for what it could be. Pressure...
  7. A/C; Steaming from engine bay?

    General E46 Forum
    When turning on the AC, a grinding noise and a pop can be heard with steam accompanying it as it rises up in spurts from the engine bay. I must note that i did get a regas recently measured by pressure and not by weight...:facepalm: As soon as i turned it off however the spurts of steam...
  8. Air con cant be regassed?

    General E46 Forum
    Been hearing a whining/groaning noise from the vents/dashboard as of late so upon further research thought itd be that the AC system was low on R134 and thus was causing the evaporator to make noises. However upon going to get it regassed the mechanics noted that at 670g of R134 (The full...
  9. [HELP] A/C Problems

    General E46 Forum
    So I just bought a 2004 325ci and it has a bunch of weird quirks that I am sorting out and fixing (mostly by myself). The previous owner of the car knew barely anything about it but I can tell that it was not taken care of very well mainly due to the grindings on the rims and the cut springs...

    General E46 Forum
    I've been having an issue with my 2004 BMW 330ci. Some background; the vehicle ran perfectly fine for a long time. Regular maintenance done one day serp belt ripped. Before replaceing figure the alternator pulls was getting stuck. But when the new parts were installed everything seemed fine till...
  11. A/C Not Blowing Cold Air, Burning Smell from Engine Bay

    General E46 Forum
    So I was driving on the freeway today with the a/c on, and I smelled something burning, and saw a bit of smoke coming. Didn't think it was from my car, so I continued driving. My A/C started to not blow cold air, only warm/hot air. I pulled into my garage and smelled the burning smell coming...
  12. Defroster problem

    General E46 Forum
    Hi! Every time i turn off the the A/C on my e46, the defroster starts blowing humid air out of the vents. It stops immediately when the A/C goes back on. I don`t thing there is an coolant leak, cuz I can`t smell any coolant. Checked the cabin filter, it was as dry as it could get. Owned the car...
  13. A/C getting warm and humid!

    General E46 Forum
    Hey y'all, I've been searching the forums and can't seem to find anything with the same exact issue that I have. About 6-7 months ago, I replaced my A/C condenser. Its been pretty good, but recently since its now summer, if it's raining or if I'm in the car wash, my A/C gets very humid and not...
  14. 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...
  15. Replaced HCV still no A/c "sippy" sound from vents

    General E46 Forum
    So I've read several threads that solved A/c issues with the following symptoms by replacing the Heater Control Valve: 1. A/c on driver side not on passenger side. 2. The need to have all or at least two levels of vents open (i.e. Floor, Mid, Dash Vent) in order to get cool air. Having these...
  16. Need Help with COMPLETE stripping of my e46 drift car

    General E46 Forum
    Hello everyone, I want to start off with saying I'm not new to modifying cars, however, I'm having a pretty hard time stripping out everything I want behind the dash of my 2000 e46 sedan. I have seen this DIY for stripping down to the dash, and I have gotten more than this far...
  17. Could a faulty FSR cause A/C blower failure?

    General E46 Forum
    So, based on some recommendations from you magnificent people, I've determined that I need to replace my FSR. Previously, the main symptom was an inability to modulate how hard the A/C was blowing. However, that has now changed (note: I haven't replaced the FSR yet). Now, the fan simply won't...
  18. 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...
  19. Finally Cold A/C!!!!!

    General E46 Forum
    Just thought I would share this bit of information that may help others with their ac problems. I bought my 323i almost 5 months ago and since day one I would have problems with the a/c. The blower would blow air however the compressor and outside fan would only engage whenever it felt...
