AIR CONDITIONING - ELECTRONIC AUTOMATIC TEMPERATURE CONTROL (EATC) - SERVICE TIPS FOR REPLACEMENT OF REDESIGNED CONTROL HEAD - VEHICLES BUILT BEFORE 4/21/90
FORD:1985-88 THUNDERBIRD LINCOLN-MERCURY: 1984-87 CONTINENTAL 1984-90 MARK VII 1985-88 COUGAR
The EATC control was redesigned in April, 1990. It has a center mode button labeled "VENT" and requires a new ambient temperature sensor calibrated to match the new control. Using the wrong sensor will bias the interior temperature 5-10~ F from the set point.
If an old level EATC control head is replaced with a new level control head, a new ambient temperature sensor (F0LY-19E642-A), identified by a white plastic body, must also be installed.
If a vehicle equipped with the old level control head (center button labeled "A/C") requires a new ambient temperature sensor assembly, use (E4LY-19E642-A), identified by a black plastic body.
If the (E4LY-19E642-A, black body) sensor is not available, use of the (F0LY-19E642-A, white body) sensor will require installation of a new EATC control head.
I cannot confirm anything with regards to accuracy of that yet..... Still hunting for the actual source as the person who posted it didn't cite anyone or anything.
Sorry for the long wait. I actually pulled the In-vehicle sensor today and cleaned it. It was quite disgusting. It may even be so bad that it no longer works. I'm looking through the test procedures in the shop manual now.
Anyway, whether or not I'll need them does ANYONE actually know the part numbers for these or the Motorcraft numbers? I know they're quite difficult to come by.
Was wondering what happened to you. Glad to see you're around. I had to make a similar decision with a Lincoln Mark VII I had. car was roadworthy, but was getting to a point where it was going to need a good amount of work and I had 4 other cars that were in good working order. In the end I let her go. Too much maintenance to have that many cars for me and I didn't feel like sinking the money into it. I still miss the car though.
I actually have a question concerning some Mexico specific parts for you. PM me when you can.
As far as I know, shorty headers don't even work with the column shifter. You'd have to convert to floor shift, or go T5 before doing the headers unfortunately.
They work. In fact equal length shorties work as well. I've been running Mac equal length shorties since 2008 and before that ran some Hooker 3/4 length slip fits that have been discontinued. I ran those for a little over a decade.
Our cars and pretty much every FoMoCo product that had illuminated sun visors had a very basic one wire feed for power and grounded to the frame through the metal mount and screws up until the 90's at some point where they went to a 2 wire setup and the mount material was switched over to plastic.
Many moons ago I found a set of early 90s Explorer dual illuminated sunvisors that were a direct swap. No cutting, no splicing.
Someone put a terrific rip in the passenger one on my car a few months ago.
I picked up a set of 03-04 Marauder Illuminated dual sun visors.... The mount holes for the TWO of the screws line up. I'll have to drill for the 3rd. Apparently they moved one of the holes with the metal to plastic mount switch..... No biggie.
Another thing. The pigtail for the newer style visors is as I mentioned; TWO wires.... I'm ASSUMING one is ground and one is power It gets better. The driver side has 2 black wires, no markings. Passenger side has a green with red striped wire and a black with orange striped wire....
I TRIED feeding power to one wire and grounding the other on the roof. Blew the fuse for the circuit.... Someone I know suggested trying to test it direct to the battery. No dice..... Also a theory..... Both wires somehow get power and the ground is the metal nub the wires come through.....
If anyone actually KNOWS I'd be grateful. I have the sun visors installed and the wires taped so that can fish them back out. It's not as if it's an absolute necessity for me to have the visors illuminate, but it would be nice. I mean the car came that way so....
