Sport L320 heated drivers seat issue.

hello chaps,
just took ownership of my first landy last saturday...yep a virgin !
its a 2008 L320 range rover sport.

Apologies in advance if this question has been asked a million times already ! but the search function does not seem to get me where i need to go.

I have discovered that the drivers side heated seat is not working... the button on the console illuminates with the 2 red dots no problem..but the seat does not heat up.

The passenger side and the 2 rear seat heaters do work fine.

Having had a quick look under the seat and removing the black plastic cover at the front I can see a couple of jack plugs near the back and some kind of module at the front with a bigger loom going to it.
There's a small green plug there too over to the outer side of the seat - with a green cable and yellow cable going to it.

Just wondering if anybody could tell me which cable i should be looking at to check for voltage or continuity ...or what I should be having a look at to get this fixed.

Any help would be appreciated.

the horn has also now stopped working...but i can hear a relay clicking in the centre console when i push the horn button on the steering wheel.
any help at all with either issue would be much appreciated !

have you tried www.rrsport.co.uk they are more clued up on the later sport models - most of us are still trying to get our head around the miracle of fire and that round wheels work better than square!

BUT - do come back and tell us what you find, that way we learn too.....

thanks very much mate, i just joined here ...i wasnt aware that this forum was more geared towards the old models.
i'll have a look over there and report back for info !
