i can attest to my '98 windstar (3.8L) that the a/c is very inefficient.
only gets cold when sitting at a stop (guess the fans are one) or doing 80
mph.

the R134 whatever is not as efficient as the ozone depleter R12

Subject: FTE Small - 8.8 inch rear for ranger

I am going to swap out the rear axle of my 86 ranger for the 8.8 in the
newer rangers. How can I tell the fifference between the 7.5 and the
8.8. Any help would be great.

If it hot out, it is better to run the AC on MAX. This re-circulates the air
inside of the truck. Regular AC pulls in air from outside the truck. If it
100 degrees outside and 75 or so inside, if you run it on max, you can
probably set the fan to low since it does not have to cool the air as much
once it gets cooler in the truck.

First, thanks everybody for your response, it is greatly appreciated.
Also, sorry about another long post.

Yesterday, I made an attempt to run through some of the algorithms in
the Chiltons and Haynes manual on diagnosing the systems state of charge. I
had some interesting results. One test was to feel the coolant lines
entering and leaving the compressor. The manual says one should be cool and
the other should be cooler (after several minutes of running). The top line
was cool and the bottom was burning hot. However, the bottom runs close to
the exhaust manifold and is insulated, so I might just be feeling the effect
of the exhaust on the insulation. Although it is still burning hot for the
entire length of the line, even away from the manifold.

I was running the truck on MAX A/C with the windows open on the coldest
setting (truck was already warmed up). The compressor would disengage and
engage every so often, but more sparatic than cycling. I thought that at
this setting with a hot interior, the compressor wouldn't disengage unless I
was at wide open throttle. I also found that the compressor would disengage
if I increased engine speed and re-engage when I decreased or kept engine
speed constant. I was slowly ramping up engine speed and the compressor
would disengage at 1300 and re-engage after I let up on the gas. I think
this is also true if I was increasing engine speed from a different RPM than
idle. This is probably what causes my driveability problems. The stumbling
I described is probably caused when the engine speed drops as the compressor
engages when I let up on the gas to shift. Then I am letting go of the
clutch and putting in the gear at a lower RPM than I anticipated (RPMs
dropped quicker than I am used too).

I should probably reiterate that my A/C does work and it does cool the
truck down, it is just that I think it should be doing it faster or keeping
up better. I have cold air coming out of the vents, but it is not frigid.
I am typically using A/C on my 50 mile drive home from work. I leave all
the windows open until I am up to speed on the freeway and then close them
and turn on the A/C.

Ideas?

More info:
-The truck was originally equipped w/ R134a and the A/C system
was never modified.
-The thermostat is not stuck closed, I didn't check to see if it
was stuck open.
-I have a 4.0L V6, 45,000 miles.
-One reason for not wanting to run it on MAX all the time is
that I don't want to listen to the blower forcing air through my vents at
full speed.

Thanks again,
Tony
