a/c repair babble

Hello proud DIYs. I have a couple of questions. Take a stab at any or
all.

1) My a/c compressor (FS-10) just froze up on my '95 Bronco. I bought
a "new" one from Pep Boys for $210, with clutch. I also got a quote
from Carquest for a new one for $315. I don't remember if that one
included a clutch, but I think it did. I asked both places if these
were new or reman; both said definitely new, I asked but neither store
offered remanufactured items, nor offered core return. Today, I'm
talking with an a/c repair shop. He refused to believe I got a new
compressor with clutch for $210. So now I'm wondering; can large
places like Carquest and Pep Boys get away with callling reman'd parts
"new"? Is there a difference between "remanufactured" and "rebuilt"?
Can I actually expect to buy a truly new a/c compressor, with clutch,
for $210? The part comes with a 1 year warranty and does not contain
oil, but appears to be sealed.

2) For the real a/c geeks: I have plans to replace the clutch fan in
the Bronco with a 2-speed electric fan from a '90ish Ford Taurus. I
understand from what I'm reading that too few cfm through the
condenser will cause problems (which is probably part of what happened
to the current compressor), so I want to be sure I'm putting enough
fan on it, and may want to use the low speed if possible. Is there any
way to come by that minimum cfm number? I'm assuming there's a
relationship between physical volume of refrigerant in the system,
high side pressure, and condenser air throughput, such that any two
could be used to derive the third, but that's me just trying to sound
smart.

3) Does anyone know cfm specs for the radiator fan from late '80s-
early '90s 3.8 liter Ford Taurus?

Thanks for the help.

Check this out:  One store that carries reman, China, and OEM.  Look at the
price difference!  They're all 3 the same!

What on earth makes you think they're literally the same? The pictures
on auto parts websites are provided just for fit reference, never trust
them to be images of the exact part referenced.

This is funny. If you click on the thumbnails to get the large scale
pics, they are also the same, but underneath they say (you have to
read to the last  line to see why it's funny):

"This is an exact* picture of your part.  We do not use generic
pictures.  Our cataloging team is the best in the industry and it
ensures that you get the right part, the first time.

"Be wary of companies that list generic or 'sample' pictures.  They
are usually fly by night operations that are rebuilding in a garage.
They do not have the expertise to build the part correctly and will
not stand behind it when it fails.

"*Exact for product identification. Reman and some new might look
slightly different.

Made in China.

The compressor probably is a complete new unit.  The problem is it
isn't a complete new OEM unit, it is a new China Cheapo that isn't
made of the best stuff or to the tightest tolerances.   If this were
an easy to replace alternator I wouldn't really care but on an A/C
compressor you are going to have to do an awful lot of work for
something that might croak in a month.  Hopefully more folks will pipe
up and give you their experiences.

I can't see you getting away with low speed unless you have some
pretty good engineering skills.  You want to keep the CFM up to keep
the temp down in the condenser.  As the temp in the condenser rises
the pressure rises and you loose cooling effectiveness.  If you are
handy with wiring and relays you could rig up a system to kick the fan
up on high when the high pressure reaches X psi using a couple of
relays and a high pressure switch (much like the low pressure switch
that currently cuts the compressor off if the pressure drops below a
certain psi).

>3) Does anyone know cfm specs for the radiator fan from late '80s-

No idea on even an estimated number or where to find it.

Stick with the stock fan. If the clutch is bad replace it with a good one,
not an el cheapo. You'll be a lot better off.

The two speed electric fans run on high speed anytime the AC is running.
I will second Big Al's advice, if in doubt, replace the fan clutch with a
high quality
brand heavy duty replacement.  If more than 50,000 miles on the fan clutch
replace it.

FWIW to the OP:

I have a '55  Ford F-100 pickup.  Actually, it's a '55 cab and bed
transplanted onto a '92 F-150 frame.  The engine is a 302 V8 coupled to a C4
transmission.   The cooling system consists of the radiator from the '92
F-150, but an electric fan was installed replacing the stock fan.
The temperature probe is installed on the upper section of the radiator.

A "Vintage Air"  air conditioning/heating system is also installed in the
truck.  The A/C has worked fine on it with the electric fan system.
Obviously, when moving along the fan does not run, but at a traffic light or
idling when warmed up, the fan cycles on and off and I've never noticed a
major difference in the temperature of the A/C air flow, even in 90 degree
summer days.

I am not suggesting this is an ideal setup or even correct, but it works.

The air conditioning on my 2000 park avenue blows cool air on the
passengers side but uncooled air on the drivers side. What is the
problem and how can it be fixed?

Go to ackits.com and have a look.  An FS10 replacement compressor, new, is
about
$215

I used one of their compressors on my Reatta upgrade (134a) and it worked
well,
very quiet.  I believe that these compressors may well be better than the GM
OEM units.

could be there is a blend door stuck somewhere.  I've also seen this
happen when a system is low on freon and only part of the evap cools
down so only one side of the air stream gets cooled off.

We had this happen on a BMW X5 my wife had.  It was the air management
(blend doors) system that was bad.  It would have been cheaper to repair if
the compressor had been bad.

Are the controls set so it does just what you are getting?

Ooooookay.  Personally, I prefer acsource.com and acsource.net for my stuff.
I am a combination DIY/licensed A/C tech.  I don't actually do A/C work for
a living.  Acsource.net has $227 for the FS10 new.  I just bought one, it
was new.  It's on my truck right now.  I cannot explain the behavior of the
guy at the shop.  The person you're talking to shouldn't be overpaying
ridiculously if he's in the business.  He ought to know better.  I have also
used the 4 seasons brand from Autozone, and those are also new, but it's a
lot better to get the real name brand stuff when you can for $200.  Here's
what they carry NEW:
"For new compressors we have Delco, Visteon, MoPar, Ford, GM, Chrysler,
Nippondenso, Sanden, Nihon, Calsonic, Zexel, Diesel Kiki "  They're not
trying to fool anybody.

In this particular application, your compressor dies of "Black Death", which
plugs the restriction orifice. Air isn't the problem.  Air flow certainly
does help keep condensing pressure down, and it really would help the
compressor have less of a load on its parts.  Will it last longer?  It can't
hurt, that's all you can say.
