Air Conditioning - Needs work!
Hi All,
Ok, summer is coming here in New Zealand and my Air Con is a little worse for the wear. The compressor needs work and I'm not sure of the charge and if any leaks etc,
Can anyone tell me what triggers the actual compressor to switch on and off as I don't seem to be able to see an actual AIRCON switch.
I am guessing that the AUTO function on the RH control switch allows this to turn on as needed but I am not sure.
Cheers

Since you have an '84 you'll have the 'superheat switch' protection circuit. If the freon level gets low enough the switch grounds-out and melts a three-prong thermal fuse. So, even if re-gassed, the fuse will need to be replaced.
If the compressor is shot there are some modern replacement out there; worth considering.
Be forewarned, though, that even if you get the refrigeration side of the system up-to-snuff it isn't unusual to have problems with the control side of the system. Some easy to trace and repair, others a real torment
Cheers

Not sure about the XJS 6.0L but the saloon uses a multi rib belt not a V belt
