Air con/heater issue

Hi there (1st post),

I've had a bmw 316i 2002 for 9 months, I've had no
problems until today when i switched the air/con heater
on and nothing came out even though the display seemed to
be working fine, i used a meter to test the fuses (they
seemed fine) and then all of a sudden the display stopped
working.

Is this a common problem? Is there anything i can check
or do before i take it to a garage?

Thanks peeps.

Thats a yes to both of those, neither the air con or the
heating are blowing any air when it was switched on, on top
of that the air con/heater display has died on me.

Hi... I've also had this issue randomly recently. Only intermittently tho. Sometimes when i'm driving along the fan will suddenly stop blowing out any air even though the display still says it is... then about 5 or 10 minutes later it comes back on again... no explanation as to why it happens but it's quite annoying!

Had it checked out on the diagnostics due to a different throttle control problem and apparently I have duff software somewhere... so hoping that this is being caused by the duff software too... they did say that no other fault codes came up so doesn't appear to be a fan fault...

(mine's a 2000 330i).

Getting new software installed tomorrow so fingers crossed...

Apparently this fault is known in Canada (???) - was an issue with cars of a certain age - dunno why it hasn't been highlighted before tho...

They may have detected software problems, but that's not your fan speed problem, it's almost certainly the FSU (Final stage unit) Item number 3 here, part number 64116929486
