XJ 40 Diagrams

Can anyone tell me where I can get diagrams or info on where specific parts are located on the car & also wiring diagrams. If anyone has anything like that they can send me. I'm trying to repair my XJ 40 1987 model but I cannot find where the items I need to repair are situated.
Mainly air con control module & the left hand indicators front & back don't work. I've checked the BFMs & all bulbs so it has to be in the module I think????
Thanks Regards Chris
