Are you saying that the ventilation system as a whole isn't working, or just the air-con?

[billy5]

nthing is working,
the whole thing lights up,you can increase or decrease
the required temp, and the fan level,butget nothing.
with the ignition on, when you switch on the whole system,
there are clicks,
were about are the fuses for the system, are they named.
do i have to go to a bmw garage,
thanks a lot, billy

Fuses are located in the boot behind the flap on the right, and in a 'drop down' fuse bank in the glove-box (twist open the white fasteners). There should be a numbered plastic strip to identify each fuse. Failing that it might be your 'hedgehog' see http://www.pistonheads.com/gassing/topic.asp?h=0&a...

hiya peaktorque,
i,ve looked at the fuses in the glove box and the boot,
the number of the fuse in thebook [75] is not there,
they only go up to 45, and there is no blown fuses,
today there was cold air coming out of the top
ut no fan, the moment i touched the fan it went warm,[off]
wat is the hedgehog?
will it cost me with bmw to get a scan
thanks billy

hiya all,
got in the car this morning, turned ignition on and
the fan came to life, first time in a week.
wat do you make of that,
wat is the intermitent fault.
it was set at 17degrees and i havent touched it in case it went off, any info would be appreciated.
thanks, billy

Final stage resistor. (fan speed controller). Not that expensive or difficult to change from what I have heard. It is obviously not a fuse at fault if it is working intermittently. The 'hedgehog' is known to fail on E39's so it is more than likely this.
