E70 X5 - Heaters not working

[x5e70d]

HI Guys, the x5 heaters wouldnt blow any air from the heaters at all?

all the functions / buttons all work fine as do the controls but theres just no air?
any ideas?

thanks in advance

Looks like very common issue, I noticed the same issue before buying, apparently it was fixed by replacing FSU attached to blower, but I now have annoying rattling noise coming

What's fsu

I have an annoying resonance humming and pulsating noise which I think is related to the electric blower
If I turn it off it stops

Maybe the fan inside the climate control causing it and at times makes a high pitch noise too

I think you mean FSR.  Final Stage Resistor.  If it fails either nothing works or the fans won't switch off.

OP:  Check the fuses in case one has gone.  Is there nothing even in 'Auto' with recirc off or in Auto? Recirc shuts off all outside air.

Sounds daft and something you have probably checked already, but I had the same thing with my car. I only had a tiny bit of air coming out of the front vents with the blowers on full whack. I had the climate set to blow air fully out of all the vents; foot-well, front and windscreen (again I'm sure you've checked this) but the real difference was made when I turned off the blowers in the center console that blow to the back seats.

Might be worth a look.

I've posted on main area with details of blower regulator and blower unit

Apparently BMW parts sell a lot of these in a month

About £100 for regulator and £200 for motor fan
