    Hi, I've been having issues with intermittent AC operation on my 03 530i. Every once in a while when I start the car the AC won't come on. It will make a lot of noise but it's barely moving any air, and the air that does move is warm. The dealer that I bought the car from showed me this "trick"...

    Hey guys, another vid I made for anyone looking to upgrade their trim to the LCI one with the LED lighting. Your car must have the ambient lighting option (you can check by seeing if the lower trim above the cupholders have an LED light that turns on when the interior lights are turned off -...

    Thx in advance. A few weeks back my AC started to quit on me and and only came on intermittently. A week ago it quit for good. I ordered a new BEHR blower from BavAuto and I replaced it today. Still no Air! I tried turning the air on full (to bypass the FSU). Still nothing What gives? Any...

    I am wondering if there is a procedure to preform an electrical self test on the control unit it's self. The AC system stopped working all of a sudden. The AC clutch does not come on in both AC mode and defrost modes. I am thinking that the system is low on R134, but just want to see if there is...

  7. 7 Series - E65 / E66 (2002 - 2008)
    Everything looks like its on and functioning on the control unit but no air is being blown out at all. No matter if I press Max AC or turn the knobs manually, no air is being blown out, hot or cold. Any ideas of what could be going on? Also, one weird thing that was going on prior to this was...

    Oh NO! Smoke with AC ON (Alternator was culprit) Ok, so today I decided to run to the store to pick up some oil to do an oil change, and I'd say about after 30 min of driving, im at the light and all of the sudden, i see smoke from the engine, not alot though but it was very thin and not thick...

    2013 BMW 535i(F10) Noise, Engine? or AC? During driving, I can hear the noise from 2500-3000 rpm. So, I tested and found it as below. In P mode, when the engine is kept at 3000rpm and the A / C is turned on, it falls to 2100-2200rpm. And when I turn off the A / C again, it goes up to 3000rpm. A...

    I understand that the newer BMWs use condensation sensors in the HVACM. Supposedly the sensor measures humidity via condensation and if it meets a threshold it will turn on the compressor to begin reducing the likelihood of fogging the windows. I think its a decent idea but like other ideas I...
  11. E39 M5 (1998-2003)
    My ac control panel is dark and the blower motor was blowing hot air on my feet even with ignition off. Pulled fuse 44 to stop blower from draining battery. Mechanic tried replacing FSU but didn't do anything, tried replacing fuses #9 and 20 but nothing. Is this the ac control unit that's bad...

    Interesting article on average freon loss per year in sample of 2,000 German cars including BMW. This would result in 1 to 2 ounces of loss R134a. So this would lead me to believe that a 10 year old car would typically need 8 to 12 ounces recharged. No additives, just 134a that comes in the...
  13. X3 F25 (2011 - 2017)
    After a long road trip in hot weather, I noticed the floorboards on the driver and passenger side of my 2013 X3 were soaked. Google searches suggest that the AC drain (?) is clogged. If so, how do I unclog it?
  14. E39 (1997 - 2003)
    I have 200 530i. I hit a deer the other day. I had some damage on the front end of the car. I have taken the front end off. Do you think the condenser is fine? What should I check on the condenser to make sure I dont have to replace it. I have not way to evacuate the refrigerant to...
  15. E60 / E61 (2004 - 2010)
    I recently replaced my compressor and my air conditioning was working perfectly for about a month and a half. Then one evening I noticed a strange sound coming from my dash area . It sounded like somebody was holding a playing card up against the squirrel cages of my blower motor. So I have...

    Someone please help me out here. A while back my ambient sensor was yanked out from under my car and the readings for the outside temp sensor would be all out of wack going from the negatives to highs of 144 degrees. Soon after that but not right away, my AC stopped working. It blows hot but not...

    Car: 1985 BMW 325e Problem: Blower Motor Hello, I bought my e30 back in January and the owner gave me an uninstalled blower motor. I installed it and it worked fine except that anytime I put the speed above 1 or 2 the spinning fans scrape against something. I'm not sure if I'm not placing it...
