1. If the blower is not working first check fuse #28 (fuse box is in the glove box you may want to pull the white cardboard out ; it is your reference) if fuse is good, possible problem in the final stage Blower unit (resistor pack)- very common BMW problem.
Part # 64-11-8-385-549.....About $95 give and take.
As to the location/changing the resistor pack blower itself? well it is located to the left of the glove Box under the center of the dash closer to the firewall. If u cannot find it I'll E mail u some pictures. GOOD LUCK
Same problem here, I own a 2001 540i, the AC stopped today in 102 degree heat. Any answers for a DIY fix. I have checked all the fuses, including 75 and 76. everything shows ok ... anything you can all help me with..
The past few days it has been intermitent. If the car is cool when I start, it is Ok. However, if the car has been sitting in the sun all day and is a million degrees inside the fan will not work. Any ideas?
when you say THE FAN, you have two fans: one behind the radiater (belt driven) this one better turn all the time hot or cold. The second is electrical sitting right behind the grill. This one is moody and kicks in with three speeds. When your car sounds like a jet ready for take off you know this is your 3rd speed- the highest speed. Let us say 100 degrees outside and you're sitting in NYC traffic u will get to the 3rd speed, believe me) furthermore 1st. This fan seldom kicks in unless the temp of the engine dares to pass mid way on your temp. gauge. and 2nd. It must kick in 1st speed whenever you press the snow button in your dash-that is to say whenever you turn the AC on, this fan will start to help the driven belt one and thats why they call it Auxiliary Fan. Expensive one though when it goes $300+ The motor in it is sealed (sorry no rebuilt) and has a mind of its own (the controllers look like small square black boxes contained in the shroud)
P.s. it's worth trying to clean the auxiliary fan because it is famous for sucking on garbage; it does love to suck and eat up tree leaves especially around this comming season. So turn the AC on and test it If it is dead look up your rely but this time look in the trunk at the right side; tilt the compartment and just above your battery; check that fuse/rely box for a starter then we will take it from there.....let us know how u make out and Good luck
