Interesting one - intermittant fault with the Climate Contro

Hello All,
Got a B5 S4 (pre-facelift)
Had this happen twice now.
The climate controls work, but the actual fan doesn't engage. I can heard "clicking" as it engages.
Any ideas? Dodgy fan?
Thanks in advance,
Dan

There is a method of displaying faults on the front of the aircon panel. Hold the recirc and up arrow or something. Will see if I can find details for you. I got a simlair issue with aircon which I need resolved.

LOL!!
Well, bl00dy typical. Fired the ignition up, and the damn climate control kicked in!!!
So, I checked a few of the obvious codes, such as 15, 16, 18, 21 (no occurrences), 32 & 33 (no occurrences)
Didn't really know what the rest was doing, so left it. Might be worth trying when the fault happens again.
Thanks for the link though!

Sounds intermittent to me

I'd have thought that the first thing to look at, would be a new AC compressor - perhaps it's faulty.....
Just a guess (what I know about Audis, you can fit on a stamp!!
)

Well, it's happened again today.
Code 18.3 (fresh air blower voltage - sporadic)
Strangely enough, after doing the test, the bl00dy blower kicked back in!!
(in the nick of time - it was getting warm outside!)
Any suggestions?

Could be the resistor on the heater box
You should be able to access it by removing the glovebox

I cant seem to get the diagnostics to work? I held down the recirc button as per the instructions but got nothing - i have got a pre facelift if that makes any difference?
Can i check the codes via vagcom instead?

Press and hold the recirculation button. Then press the manual flow control up arrow
or check with vagcom.
