Your statement that I responded to wasn't the above, it

"In the good old days you would just jump 12V to the compressor to confirm its ability to function. Now days all parts up stream must be working before system tests will complete."

So, stop lying. And all I said in response to that was that AFAIK,
you can still just jump 12V to the compressor as a test, just like
you could in the past. I thought it important to clarify, for people
like the OP who are seeking help in how to diagnose, how the AC
system works, etc. I didn't get nasty, didn't take shots at you.

And now you want to take cheap shots at me? Owners that maintain
cars like me? YOU don't even understand how the AC clutch works
with the rest of the system, as evidenced by the above. And when
you post something here that's incorrect, when someone points
that out so that others won't be mislead, instead of just correcting
what you said, you deny and try to divert. And now
you want to drag DISA in here? Yeah, I've driven it for months
with the DISA inoperative because I understand what the DISA
does and doesn't do. I made that call. Same thing with the aux
fan. It's the third fan in the car and I'm rather tired of paying
$450 for a new piece of junk one. It's a terrible idea, putting
electronic components, unprotected, in one of the worst environments
possible. So, in the summer I don't have cool air for a minute
when stopped at a light. For me, that's an acceptable tradeoff.
And maybe the X is the only car you have, you use it to haul
your boss around in or you're deeply in love with it. In my case,
the X is a seconday service vehicle I use primarily when I need to
haul something, to go to ski resorts, etc. It's only worth a few
thousand bucks, I'm not too keen on pouring money into a high
mileage, 13 year old vehicle that's only worth a few thousand
bucks, for non-essential items.

Further, what I learned from the above directly contradicts what
others here have claimed. For example, some have claimed that
the AC will not run at all without an operating fan. I think 2 years
experience that proves that wrong is useful information for
anyone trying to understand how the system really works.
Same thing with DISA. It's useful info, because some people
thing that without a functioning DISA, the car won't run or
will run poorly. Apparently that kind of useful information
upsets some people here, like you.

Like I've told others here, your car, your money, your choices.

But just man up to what you actually posted, instead of taking
cheap shots and starting a divisive argument.
