XJS 2+2 A/C
1994 XJS 2+2 convertible 6 cylinder
I attempted to service the A/C on my Jaguar. I had the low side pressure up to 35 psi, the compressor was running pretty regular and the discharge air felt cold
All of a sudden there were a couple very loud "chatters". Smoke rose from the exhaust manifolds and I could not track down the source of the leak, which I assume was freon.
I found a similar post to my condition, and it seems the culprit could be the pressure switch, DBC 11279
After looking at some photos, my question is should I just try and replace the o ring or should I replace the entire switch? Is this a high failure item?

I’ve not heard of any part being a high failure rate part on these facelift Cars for the AC.
Are you sure that’s where you lost the refrigerant?
Id invest in a few cans of R134a without any sealants or anything else, you’ll need three 12oz cans to refill the system, so you may want to buy some extra.
Buy the drier, since that gets replaced anytime you open the system up to the environment.
Get some dye and a black light flashlight and see where the leak is! (Some cars already have dye in them, perhaps all you need is a black light.)
Get an AC manifold from Harbor Freight if you don’t already have one.
Your biggest obstacle will be the vacuum pump. If you can rent one from an auto parts store, you’re all set!
