2013 X3 - Heater Fan issue?

Did anyone have an issue with their heater fan not working in really cold temperature?
I have a 2013 X3 28i and on a really cold day (-30c) after starting my car, I turned on the cabin fan/heater and nothing happened. There was no air being blown into the car cabin no matter what temperature/fan speed setting I chose.

I ended up driving with no heat for a few minutes and once the car warmed up the fan started working normally again. I am suspecting it had to do with the very cold temperature we had that day and the fact that the car was parked outside overnight. Something may have frozen and prevented the fan from properly working!

It seems odd that this would happen on a new BMW, and I was wondering if anyone had a similar experience.

This only happened once (on that day when it was -30c) and the fan seems to work normally since.

Just wondering if I need to be worried about it?

Thanks.
Hesham.

Likely not an issue

Sensors look at ambient temperature. Fan won't activate until engine has warmed to the point where you can be spared a blast of icy air coming from vents.

I thought this was a problem, but check the dial beside each vent. You can actually change from cold to warm.

I thought that was only on the center vents.

Sorry, the centre front/rear vents only. Don't understand why you need to change the temperature when you can set the value on your centre console.

Not sure why they have this secondary temperature control for essentially the same purpose.

Some people like the cabin at a certain temp but prefer to have cooler air in the center, which is more likely to hit their face. I think it is kind of a 'safety' feature, as cooler air on your face is more likely to keep you awake if you are tired than warm air (but I could be wrong about that).

The heat comes from the engine not the "heater". With the hvac on auto the fan will not blow cold air on you as per this post.

If you prefer -30c air blowing in your face you can drive with the window down with your head out the window or manually turn the fan on high before the engine warms up.

On those cold days I prefer not to have cold drafts but the steering wheel and heated seats cranked.
