Climate conrtol problem

[MC 357]

As topic says, when I turn the fan on I can hear it working but no air comes out from any of the vents. The only one that works is the windshield defroster.

Any idea what can be the problem?

Can you Adjust air temperature? If one of the stepper motors have failed then the car goes to "emergency heat." That will only allow defrost on max heat.

Here are a couple of threads on the topic:

Help!! Air conditioner just started blowing hot air!

Z4 Blowing only hot air, at random

youre ac may have gone into "transport mode". My car did that this past year.

there are more links but here are a few.

I actually have had that happen to me twice in the last two months. What helped was turning the air direction knob to have the air blow in a different way, and then it would "kick in" and start blowing air. I have no idea what the actual problem is... would like to hear about a potential solution before bringing it to my indy.

So i started the car this morning and everything works fine...lets hope it "fixed" itself!

I hate when any car I have owned fixes itself.
