MG ZS 180 Mk1 air con wiring needed !

Hello everyone I've just bought a second hand ZS 180 to find that the air con is not working...I checked the relay box and fuses and they are ok, the bottom on the console working...now here comes the tricky part...after taking off front bumper I found there's only one of those metal relay that control the fan unit, when I thought there had to be 2 one for each fan...am I right ?

Garage did a leak test and there seems to be no leaks but when re-gasing nothing happens....would like to know what the tori trinary switch is for and how to check if it's working alright.



Of course any other check points will be welcome.



And does anybody have a wiring diagram for the air con ? Haynes manual has nothing about it...deceived.



Cheers and thanks,



Alex
