This is just a test to see if the clutch engages and the system has the correct amount of refrigerant. You should not drive with the car set up like this since the system is designed to cycle off and on. With 12 volts jumped to the compressor, you eliminate the cycling of the system off and on. If he has a bad aux fan the high side pressure will build to the point that you can blow out the condensor coil or a refrigerant hose. The high side sensor prevent this from occurring, but it won't do this if you have the system jumped.

Another shade tree mechanic fix. Fix it right or don't fix it at all. From you previous posts I see that you are taking my advice about not fixing stuffs that breaks on your X.

So, again, shade tree or whatever you want to call that test that you
could do in the past, AFAIK you can still do it with the X5 today. Your
statement implies that it can't be done.

"From you previous posts I see that you are taking my advice about not fixing stuffs that breaks on your X"

No idea what that refers to or means.

Nope, my statement and explanation implies that this should only be done only as a test. It should not be considered a FIX or a work around to get back AC in the car without fixing the real problem.

Let See my statement was Fix it right or don't fix it.
You have a broken DISA valve that you know of, but didn't fix but still drive the X.
You have a broken Aux Fan that you know of, but didn't fix but still drive the X.

Glad I'm no longer in the market for a X. With owners that maintain cars like you I can see why there are so many noobs coming on this forum after purchasing a use X.

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.

Go back and read post 21 and 24.

As for the post that you responded to I didn't post it.

http://www.xoutpost.com/1042461-post23.html

Why don't you post picture of your broken aux fan(s)? I posted pic of my broken aux fan. If your failure mode was the same as mine then I don't know why your ac is still working.

Not a cheap shot, I stated either fix the X correctly or don't fix it. Obviously you chose to not fix the X. That is your decision.

So when you decided to get rid of the X and sell it to a new X owner are you going to replace the DISA valve and Aux Fan? Probably not and probably won't tell the new owner about these two problems. New owner will search the internet and ask why his X lack power in the mid range and why his ac only blow cold air when it is moving but warm air when it is stationary.

As to posting pictures, the fan is in the car, I'm not going to tear it
out just to post pics. And pics aren't likely to do much to solve
the question of what exactly failed.

"So when you decided to get rid of the X and sell it to a new X owner are you going to replace the DISA valve and Aux Fan? Probably not and probably won't tell the new owner about these two problems. "

And there you go again, with more totally unsupported personal attacks.
Is that what this forum is about now? As to lacking power in the
mid-range, you're once again in over your head. I've seen absolutely
no noticeable difference in performance with the DISA working or
disabled. I have seen others here report the same thing. Are you
going to personally attack them too?

What about the other fan that you have already spent 450 bucks to replace?

So, stop lying.

I think you started the personal attack when you called me a liar.

My post said nothing about what the final solution is. It was not
a "fix", it was a test suggestion. In fact, I only made the post to
clarify StephenVa's post that said you can't do this test with an X5
like you could in other cars. And to that you started the attack by
calling me a "shade tree mechanic" and making snide remarks.
And you are lying when you imply that I ever suggested anything
like that as a "fix".

It's a curious thing. I get jumped on by you. Yet in
another recent thread, there were a couple of buffoons claiming
that it was peachy keen to go ahead and change an alternator
without first disconnecting the battery. He even had a picture
of the energized alternator cable suspended right in the work
area.l Now *that* is something worthy of correcting, worthy of
warning, interjecting. Yet, guys like you were silent on that.
But I'm the shade tree mechanic. Go figure.

Since you know how to quote people, why don't you quote me in the above referenced thread, instead of just typing something together and claim that I made a post on the thread.

The posts I quoted are right here, in this thread.

#23 Where I said:

take the car for a drive, which provides the necessary cooling for
the condenser. If it blows cold air, the system is working. Should

#24, Where you started the attack. You quoted my post above,
and said:

"Another shade tree mechanic fix. Fix it right or don't fix it at all. From you previous posts I see that you are taking my advice about not fixing stuffs that breaks on your X."

Just you, in your own words. And it's an obvious attack based on
a lie, because hooking 12V up was for a *test*. StephenVA claimed
that you can't do that test with the X5, like you could with older
cars. I thought it should be clarified, so I replied. Neither
Stephen or I ever suggested in any way that it was a *fix*.

Feel free to apologize at any time.

I can find my posts, not the post that you said I jumped all over you about some alternator. PS until your last post no where in your previous postings did you ever mention that hooking up 12 volts was for a test. My two posts stated that this should only be used as a test.
