I'm still pretty new at this, I recently bought this car but a month ago and the AC does not work I have a 2 year old son and I live in Missouri so I feel obligated to get this figured out I use it as my daily driver. I have pic. At bottom right of my radiator, I believe is the fan switch, where the previous owner decided to do some self wiring. They have a red wire and a black wire going to a white wire and black wire and a white and blue wire. Is that something I need to convert back?
And then there's this, it's messy. I really need help. The compressor is not locked up, the belts are worn out. I plan on replacing first thing, just not sure what size, Thank you everyone in advance, it means everything to me. Bottom view Bottom view
There is a quick and easy way to test the required radiator fans for proper AC cooling operation as there are 2 freon pressure switches one being bypassed in a TSB that also control 1 or 2 fan operation ..
The oil leak commonly comes from the hoses on the bottom of the resavour and you can cut an inch off the existing hoses for some fresh rubber .
Check your condenser mounting bushes (the "radiator" in front of the radiator) particularly the lowers. They tend to rot or go away, then your condenser rubs a hole in itself against the car's structure. If you have this problem, the a/c system will not hold a vacuum. Also, before any vacuum and recharge, you'd do well to renew the receiver/drier, mounted atop the condenser. $30ish in parts - they tend to vomit their dessicant pellets over time which creates a nasty clog at your TXV.

Agreed, with any AC problem on the X300/X308, this should be part of the preventative maintenance, especially since it is so easy and inexpensive.
.....and ALL of the cars by this age have had their bushings rot away.
One should change the radiator "donut" bushings while at it too. Again, easy 30 min job, maybe an hour if you take a break
And as said above, the power steering leaks (slow seeps really) on the low pressure (ironically) supply and return hoses is very common. Heat from the exhaust hardens the hoses and they leak at the reservoir clamps and seem to just weep through the hoses over 20 years.
Fortunately they are very easy to replace and also relatively inexpensive. Don't forget the new o-ring at the hose end.

Excellent post, Vee, but the integration of the AJ-16 into the XJS seems to be slightly different from the X300 as to drive belts. And by "different" I mean harder to change....unless you run into problems with the long, 1/4" drive idler pulley adjustment rod as some members have. Alternator arrangement seems to be the same, however.
