Subject: FTE Small - A/C clutch engages by itself

I think my truck is posessed...
The a/c clutch will engage without the a/c button being
activated...seems like it 'cycles' a bit then disengages. For now I've
pulled the plug to it so it stops. Any idea what would be causing this?

When will those wretched manuals get here???

Ford has the A/C compresor run in every position except Floor and Vent.
regardless of the AC switch

I assume you are refering to the 90 Ranger. If it is like the 89's, it is
in the defrost position, it will turn on and off, even if the fan is off.
I think they changed to the new style of a/c control in 92 or 93, so it
should only turn on in the defrost position to my knowledge.

For the model years of Fords that this code scanner handles, it is
nice to have, but not necessary.

My Merkur Scorpio (Ford import) has a 2.9 V6 just like the Bronco II
et al and has the same EEC-IV computer. In the case of the Scorpio,
it has a check engine light on the dash. To run a computer diagnostic
(code check) I simply take a spare piece of wire and jumper two
terminals on the EEC-IV diagnostic connector (the same one you use
for your scanners) and I sit in the engine seat and watch the check
engine light flash. Not bad for a piece of wire worth $.01.

Now, some vehicles don't have a check engine light. Our Bronco II
doesn't (nor did our other Fords) so in addition to that jumper wire,
we had to connect a 12 V test lamp from another lead on the
diagnostic connector to the positive terminal on the battery. There's
no reason you can't run a length of wire that will enable you to run
the test from the seat as well.

Now, I know that some people aren't good at counting the light
flashing - some of these code checkers probably count the signal
pulses for you - some of them probably read the high speed signal
which occurs at the beginning of the test. But over time you get
pretty good at this.

Yep, I do the same thing in my Aerostar. It's not hard and for the codes I
have a book from Wells. I just wonder how you can read the codes in the
"Engine On" mode. I guess you have to have a scanner then.
The easiest way to pull codes was in my '91 Chrysler LeBaron: you had to
turn the ignition on and off a couple of times and the check engine lamp
would start to flash codes.

The older GM's (94 and older) you short pins A and B of the diag connector
under the dash then turn on the key... Count the flashes of the Check
Engine light and your set.

You read the KOEO (engine off) and KOER (engine running) codes
exactly the same way.

Subject: Re: FTE Small - A/C clutch engages by itself

Ford A/C compressors have this feature to help prevent the seals from drying
out in the seasons when it is not used. By running the compressor even when
it is not needed it keeps the oil circulating and avoids many of the
problems compressors had in older cars, mostly the front seal going out. Now
when the front seal fails it is almost always because someone has
overtighened the belt.
Hope this helps.

I remember an old Buick (GM) I had that did the same thing. I think theyre all
wired to go on in defrost for the same reason.

How do you do that? Connect the two pins and then START the engine instead
of just turning on the ignition?

Tom Ucen

BTW: In my '92 Buick Park Ave. the plug was hardly accessible. Now that was
the worst system I experienced. I praise the lord for my Ford :-)
