Hey all,
The A/C on my '92 finally quit on me last weekend (or, at least that's when I discovered it had quit)
I have been able to determine that the compressor clutch and the associated relay in the power distribution center are both ok, so it's looking like the "low pressure switch" is interrupting the power feed to the compressor clutch. According to the FSM, that switch (located on the "left" side of the condenser, though I'm not sure whose left they mean - theirs, mine, or the XJ's ) goes to an open state when there's insufficient refrigerant charge in the system.
As a result, I'm going to have to take it to someone to find the leak and fix it. That's where my question comes in.
By now, several of you must have converted their XJ's R-12 system to R-134, so I'd like to hear how it works post-convert. My mother's '91 shadow has had this conversion done, and in my mind, the jury's still out as to how well it works. I think it's ok, but I don't spend much time in her car. Also, since it's the only vehicle I've ever been in that has had this conversion performed, my sample set isn't very large.
All opinions are welcome.
TIA,
Rob
P.S. Before I forget, has anyone ever heard of the afore-mentioned low-pressure switch failing?
