    Hello guys!

    Hi everyone, new here. Just wondering the best site, as well as best FSU to order. I heard Behr and their co-company is best, but there’s another brand called, “Intermotor” selling at a very high price. I’ll pay more the better unit, but is it worth it? Car is a 97’ 540i.

    Hi I noticed this after I bought my 08 535xi. If I pull fuse from trunk.for AC (64?) Then it goes away. Is it FSU like a lot of others are saying or is this just one of the things? Is there a way to check if anything else is on? I pulled Multimedia fuse and it didn't affect it. I pulled heads...

    Did BMW change the design and location of the AC blower final stage unit?
  5. E89 Z4 (2009 - current)
    Just wondering if anyone can help? I have just replaced the FSU on my blower fan, it fixed the blower fan for about two hours and then stopped again, only working on low speed again... Could this be in transport mode now? I had to disconnect the battery to remove the airbag to get at the...

    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...

    Team, (2009 BMW X5 35D.) Problem: The front blower for both heat and AC is not working at all. It slowly had gotten worse with blowing then quit altogether. Rear heat and blower are working when I check off (Use Front Settings. I'm stumped on diagnosis and parts and there is no recall on this...

    Hey all, First post! I have a 2002 E39, and since I've had it, the aircon has never worked. It seems like the usual problem of the blower not blowing, but the usual fixes don't seem to help. The control panel seems to work fine, but I replaced it to see if that was causing the problem. I...

    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...
  10. 7 Series - E23 / E32 (1977 - 1994)
    I am a new owner of a 1993 BMW 740il. The symptoms I had when I first bought her was a very loud squirrel cage when run on max high for the fan setting. The blower would not work at all on any other setting other than the fan on max high. It was also giving off a faint dead mouse smell, could...

  12. X5 E53 (1999 - 2006)
    My air blower motor all of a sudden stopped working. Car: BMW x5 e53 2003 I have tried to connect the air blower motor directly to my car battery and it was spinning then, but when connected back to the installation the motor is completly silent - doesn't work at all. Hence in my opinion it...

    Hey guys first post here after selfishly abusing your amazing knowledge for years. My 1997 328i with 260,000 miles would not be on the road today if it weren't for all of the help from all of you. I really appreciate your problems :) So into my issue. I started having an intermittent blower...

    Hello all, I have an 03 330ci with no air flow. I hear the fan motor running but there is no air in any of the vents. Oddly enough though, when I turn on the defroster I do feel the air on the windshield. I have done lots of research so I either need a new blower motor fan or a new FSU (final...

    So at about 140k miles my blower stopped working completely, through research I decided to replace the blower motor resistor. I bought an aftermarket FSU from auto zone and put it in and it worked for a couple of says. Then the speed control stopped working and sometimes it wouldn't blow at...
