Heater Blowers not comming on except for selecting Defrost only

[DanLewis]

So about two weeks ago my heater would just not come on, it was a really bad time for it as I needed the defroster after about 15 minutes it suddenly came on and was blowing fine. I bought a aftermarket ceramic heater in case I needed to defrost my windows and it did it again.

Well it did yesterday in the -50 windchill day but I discovered that if I select the defrost only it blows just fine but my feet freeze. The heater has not started blowing again since then I have defrost only. Anyone else have this issue? I was hoping its a fuse but how is it working in defrost?

BTW I have a 14 X-1 with the cold weather package so thankfully my heated seats and steering wheel helped. I also added a omegalink remote start so I can start it and let it heat up in the really cold weather.

You battery is starting to loose it's capacity.
My battery is on the way out and anytime I leave it sitting or it gets we'll below freezing for a while this happens.
Drive it for a nice long trip with no heated seats on or wheel and the next time you start it up it should be fine. Or wait till it warms back up, or just get a new battery.
When it starts to get worse you'll get high battery discharge warnings, your tpms will start to fail, and comfort access won't work at times.

Ha, she gave up today. I was trying to hump it along till the end of winter, didn't make it.
This morning my dash lit up like Chernobyl when. I tried to start it.

Just a heads-up on this: If you make a lot of short trips, a new battery probably won't solve your problem. I have this same problem every winter, and the new battery I had installed this summer did Absolutely Nothing to solve the problem.

The real problem is simple: BMW designed the charging system to focus on fuel economy - Even if the battery is going dead! I am amazed (and angered) every winter that they went to the effort of putting logic into the ECU which limits fan speeds when the battery is low - and when those higher fan speeds are most critical - rather than just telling the alternator to charge more aggressively. The "official" solution is to buy a trickle charger - and apparently leave your hatch open all night long or slam a power cord in the 5th door.

BTW, to the original poster: By turning on the heated seats and steering wheel, you unfortunately made the problem worse. I'm rather surprised that BMW doesn't disable those systems when the battery is low as well. But I understand why you did this. The first time I had this happen, I assumed the fan was broken. Never occurred to me that this sort of behavior would be designed in.

Same thing happen to mine after being park outside at the airport the last two week in these sub-zero temperatures. After the 45 minute drive home and sitting in my garage overnight out of the wind, it was fine the next day.
