Thanks. I sanded the three metal fingers it looked a bit oxidised. Also rubbed the tracks with the sand paper but that didn't seem to do much.
Both the fan control, and the temp up/down switches seemed intermittent. I couldn't see anything wrong with the rubber membrane switches though, not sure how to proceed there.
I ordered a bulb kit with the replacement zebra strip, as while the display worked okay, I guess I should just sort it all while it's apart.
As for auto mode, I find different cars deal with that differently. In my A4 for instance full auto seems to make strange choices on where the air goes, but if you manually select say footwell and windscreen, the fan control remains on auto and you've only changed the direction.
I've not played with the range rover too much, but from a cursory look it seems if you adjust anything knocking it out of auto, the fan then ends up static. I'll experiment a little more with auto mode. However I do often find it will make decisions that are annoying. For example on a cold day the A4 will run the fan at a low speed until the engine warms up. But then it'll run the fan at full bore to get the cabin up to temperature which I find a bit too much.
