  1. Something at Fuse 50 started drawing power after stereo change

    General E46 Forum
    tl;dr - Fuse 50 draws power (fsr, blower). FSR was changed recently. Vents behave weirdly sometimes. Is it the blower? Long story short I installed a new head unit and battery went flat after the night I installed it. I believe this might have been the acc sleep setting that was on auto which I...
  2. No power from heater/AC?

    General E46 Forum
    Howdy - I've just gotten my reliable 2002 325i working again and there are a few issues I need fixed stat. First is the blowers - when I turn on the vents, no matter how high or what temp I set the system to, I get no air flow. My previous mechanic had said it was either the blower motor or...
  3. Is my FSU the problem for 0 fan (volt and ohm readings done) ?

    General E46 Forum
    Hi all, For some time I have no fan at all, so no windshield blower against condensation, which is a problem here with much rain! I'm talking about my 2001 320xi. So, I pulled out the FSU today and did ohm and volt readings as suggested. But there's no real comprehensive guide I think. I...
  4. 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...
  5. Replaced FSR/FSU, blower still craps out

    General E46 Forum
    Recently my fan would not work on some days, and work on other days. I'd turn the fan up all the way and there would be no air, but sometimes it would randomly come back. I thought it was the Final Stage resistor, so I bought a new Behr one and replaced it, but unfortunately I still have the...
  6. Blower motor issues (yes I read a lot LOL)

    General E46 Forum
    Hi Guys and Galls, Enjoying out 320i T (2002) for a while now. (also have an E38) Bought it from an old lady (really) and did a bunch of preventive maintenance (WP, T stat, VCG, plugs, all filters, vacuum lines, MAF ect) she is doing great. BUT I have an issue with the ventilation that has me...
  7. Weak Blower

    General E46 Forum
    I've noticed that my blower seems to not change the amount of air that comes out of the vent, no matter if it is on low or high settings. It's blowing cold and hot just fine, but the actual amount of air that is coming in does not seem to change. I can hear it get louder as I increase the high...
  8. FS: ECU Blower / fan

    For sale, used ecu blower / fan Two prong connection $25 shipped Squeeked/chirped occasionally so could use some greasing up (price reduced significantly to reflect this). Didn't seem to affect operation though.
  9. AC/Fan Mystery-Doesn’t Work At Random Times

    General E46 Forum
    So I have an AC issue that I can’t seem to figure out on my 2002 325i. Over the past couple of weeks I’ve experienced the general fan and air conditioner not working at all in all of my vents. No air whatsoever. This will happen, and then I will leave the car sitting while I go grocery...
  10. Climate control stopped working!

    General E46 Forum
    so, last night It was hot and I had the a/c going. I hit a series of bumps at a fairly high speed and lost all climate control. None of the buttons, including my rear window defroster will come on. Could this be a fuse or could I have done something alot worse? Where do I start? Thanks!
  11. 2003 E46 330i Fan Blower Motor Intermittent

    General E46 Forum
    More electrical problems with my 2003 330i. Now my AC blower fan comes on and off MYSTERIOUSLY by itself. However, I have noticed that when I shift things around in the trunk or perhaps slam the lid, the fan will come back on. Anyone have any clues as to what is going on?
  12. 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...

  14. AC Blower runs even with the car OFF

    General E46 Forum
    OK, here's a new one. Driving the car at around 7:30 on a mild night. The blower suddenly increased speed, and since I had it on Auto, I thought that maybe it was colder outside that I thought, and the AC (or rather heat) was compensating. I took the AC off of Auto, and manually turned the...
  15. ESS Tuning TS1 Supercharger Break-In

    Forced Induction Forum
    Hi everyone, I recently installed a ESS TS1 kit on my '02 325i auto. This is the only performance mod done to the car. I drove the car soft for the first 100 miles as recommended, and it didn't feel too impressive. Understandably so, because I wasn't really throttling it hard. After 100...
  16. Getting little to no heat

    General E46 Forum
    2000 323ci 160k miles. I'm getting little to no heat from any location on the climate control (top, panel, floor). Also, when I have the panel vents blowing the air flow is greatly diminished when I turn the dial (in the center of the center vent) to max hot, with the blower remaining on the...

  18. Blower Fan DIY

    DIY: Do It Yourself
    Did a search on the forum for the lovely "cricket sound" that occasionally appears in our BMWs. I do have the same sound and I know it's the blower fan motor, the one that feeds air in the cabin. I can hear the cricket sound very well on the lowest fan setting and it goes away as I speed it up...
