Hi Guys
The heater blower on my 2004 L322 (V8 4.4) recently stopped working.
All lights etc on control panel were working, just fan would not run.
A friend knows a chap that works for a local LR dealer so took it to him, he had car for two days and could fix problem but said I needed a new entire control panel.
Not convinced he was right, I did some research on internet where advise was fault was probably the Final Stage Resistor (FSR).
Decided to try this and found a really good guide on how to change the FSR here: The Metric Rat » Blog Archive » Replacing the Final Stage (Blower) Resistor on a L322 Range Rover (MkIII) 2002
Ordered the FSR from: www.worldcarparts.co.uk which was delivered within 24 hours.
Set about changing the FSR yesterday, follwed the instructions from Metric Rat. Job took me ( a novice) about two hours, very fiddly but eventually managed to change FSR.
Heater fan now working great :)
Just thought I'd share this incase anyone else is having similar problems.
 
The fan / blower resistor that controls the fan motor can fail which can make the fan stop working but the lights still act as normal

Sounds like they could be trying to rip you off

The climate controls in the l322 rarely fail, it's usually the resistor that goes

There is an upgraded one available
 
I have a 2009 L322, supercharged Rover. The AC fan stopped blowing. After changing the final stage resistor (SFR), the fan started blowing again. One month went by, the fan stopped blowing. I changed the SFR again and cleaned the plug contacts, the fan started blowing again. One month later the fan stopped yet again. After trouble shooting the problem, frustrated, ruling out everything, (e.g. SFR, fuses, grounds and climate control), fan still would not working, i resorted to shrink the female connector plug contacts to the SFR with a sharp metal object by pushing between the plug case and contacts, connected the SFR to the plug, the fan started blowing again, no issues. Gotta love British electronics...
