i got the 93 taurus shop manual from helm, $65
got problems with it, tells you to cut the red wire at pin No. 22 on the
CCRM, there is no red wire on the Pin 22, its on the pin No. 24.. so i
cut it they then tell you to start up the car and see if the relays let
the a/c clutch engage.. well it will not start with the red wire cut,
but the voltage does go to the a/c clutch... i then reattach the red
wire and it starts right up and the a/c clutch has voltage so i figure
thats the problem... the a/c is working now.... stop the engine and
start it up and then the same problem, no voltage to the a/c
compressor... wait a while and go out and try it again and its working
fine.... turn it off and start it back up and no voltage to the a/c
compressor( do i have a sticking relay in the Constant control relay
module????)... i got the Electrica/Vacuum trouble shooting book from
helm today.. opened it up and it was full of grease and kinda busted up
and there where sheets of paper where someon was making a list of what
parts they needed.. i calle helm up and told them i thought i was buying
a NEW book... they said just send it back.. well i told them i dont want
to pay a $10.00 return fee to get a new book.... i was then told to not
return it and they will send me a new one...... no charge.. kinda hard
to believe, but then who would have believed they would have sent out
the book in this shape the first time???? the book did not help me too
Page 12-00-30 ford 93 taurus green shop manual
diagram shows pin 24 going to the EEC. So you cut the wire
to the computer. No wonder it would not start.
The used manual sucks ( if you paid for a new one)
I bought all mine on ebay so there all used.
On my 93, pin 23 is black with a yellow stripe
this should be the A/C clutch power feed
pin 22 is red with yellow stripe
this should be the A/C cutout wire into the module
Pin 21 is red with blue stripe
This should be the A/C function switch from the climate control.
If you note page 12-00-40, it states that a engine coolant sensor as well
as the TPS can cause the A/C to be sent the cut off signal on pin 22.
removing the pin 22 wire (note: its not RED on mine but red with a yellow
stripe) will take the cut out of the circuit and will isolate your problem
to the relay module, or the feed from the computer. Note also: the coolant
DOES NOT run the temp gauge on the dash. So you could have problem there and
it will not show up on the gauge directly.
The Helm manuals are excellent but I have seen them get wore colors
wrong several times. Don't relay on the corors too much, follow the
appropriate wire from the connector drawing which should be correct.
