FINALLY got it to the dealer with a two page "This is what we're seeing", and immediately the guy is "YIKES, Sure does look like a PCM, but if I start doing diags on all of this, you're going to run up a couple grand in repairs, let me get my guys on it on Monday". Monday comes around, get a call..."New battery". We were "But it checked out GOOD a month ago when it was checked during an oil change at your place. He said "Original battery...6 years old...at that point they are day-to-day. Popped a battery in it, and done. Glad the dealership didn't take us for a ride, they could have.

Your 1965 Ford Mustang didn't have emissions and mileage requirement to deal with. That was the primary reason they had to get rid of carburetors and move on to electronic ignitions and electronic fuel injection, all of which require computers to function. These systems also enhance reliability and drivability in modern cars. Then on top of that people want all these nice automated features in their vehicles. I'm not knocking your Mustang but times have changed since 1965.

This is why I used to interrogate my customers with a bunch of questions even if they didn’t make any sense. If they told me that the instrument cluster was replaced and that’s when the A/C problems started I would figure that the problem was there. But if that was replaced in the winter then that’s a different story… I personally think the auto industry depends way too much on computer controls for everything too… This is when old school was better…

I recently bought a 2003 Lincoln Town Car - weak AC. Also leaking coolant from the intake. Installed a new Ford intake manifold. Compressor sounded like marbels in a food processer. Orfice was plugged with metal. Replace complete AC system using Ford parts. Replace intake manifold - now I had no compressor engagement. Nada. Used my Autel - couldn't even engage the clutch. Command was sent but not working. After an hour of tracing and verifying wiring integrity, I was led to G106 - a ground. One lousy ground with an insulated eyelit that snaps over the stud on top of a bolt on the valve cover - I had snapped it on stud of a fuel rail hold down bolt - dumb. Moved it over, Compressor fired to life, and all is well. You really did have to think outside the box on this diagnosis - even service data was missing the data flow from button to compressor. Nice to have that background knowledge...

@joevignolor4u949 2 жыл бұрын

On a modern vehicle ground in one place might not be the same as ground somewhere else. There can be small levels of resistance or inductive reactance between one ground and another. This can result in different voltage levels being present at different grounds especially if there are large amounts of current going from a source to a load through the intervening engine or body structure. I just did a big job on my Lexus and was very careful to put all the ground wires back exactly where they originally were and I didn't have any problems afterwards.

Follow the signal (power) flow from the A/C panel to the compressor clutch. Service information can show that. I once had a F550 that had its backup lights (and alarm) come on while in drive or park. With my DMM on the output wire at the PCM that went to the B/UP relay in the fuse/relay box and my old Fluke scope monitoring the signal from the transmission to the PCM, I ran the truck in park. It took a while, but suddenly there it was. The transmission signal was rock solid, but the PCM output signal was going on and off erratically showing in the DMM'S display. That's when I said "I got ya!" One Ford reman PCM and life was good in F550 land. Ya gotta love those intermittent and non intermittent problems going through multiple modules. Good one Brian!

I have a 2008 Explorer with automatic temp control. The outside air temp sensor suddenly failed for unknown reasons. I watched the temp reading on the dash go from 85 to -20. When it was a low temp, the A/C turned off and heater came on even though outside temperature was about 85 degrees. Replacing the sensor solved the problem.

@FordTechMakuloco Incredible info on your AC series. I've about watched them all now, but I can't find any coverage of what I am experiencing on my 2007 f-150 5.4L. I just replaced the compressor, dryer, and orifice tube. The oil in the system was very clean, and the orifice tube was also very clean, so I did not have reason to suspect any contamination in my system. After buttoning up the system with the new components, I vacuumed the system and let it sit at around minus 28psi for several hours, ran the pump a few times during that time frame to keep sucking moisture out. All looks good. My truck holds 34oz of R134, so I purchase three 12oz cans(36oz total) and put all three cans in the low side as you are supposed to. Yes, that is theoretically 2oz over, but I subtract a little for the loss through my hoses when releasing pressure and checking things a couple of times. AC turns on and cools pretty well, but both my high side and low side oscillate up and down in unison. It's not the traditional low freon symptom where they move in opposing directions as the compressor turns on and off. It did do this as expected after the first can, and through the second can as well. Now, after 3 cans, my low side averages about 25psi, with slow swings up and down plus/minus 2 or 3 psi. I'm thinking I'm low, but not confident at this point. Any suggestions?

Thanks for your good work and this is probably the most unfriendly and deliberately frustrating "Pay or Play" system ever designed except for certain BMW and Mercedes cars. You're like the Road Warrior. God bless you, Brian. The "netwerks" in these cars seems to be designed to have minimal fault-tolerance and maximum failure rate, precisely the opposite of the way the Internet is designed, literally turned on its head, so that at every turn you are totally lost without spending big $$$. It's frightening that people have to learn this total crap to get a "certification" but tha's the way it is. Everybody is being led around by the engineers who design these systems to be almost impossibly difficult-to-diagnose garbage. By the way, I advise you to open a really good restaurant for your fallback career once all this nonsense junk comes apart, which won't be too long now. Make Japanese Teppanyaki and on the other side of the restaurant, Mexican street food.

Found the positive battery cable had a voltage drop that was causing the entire problem. Crazy.

Just watched this video and a very interesting one for sure! It's unfortunate that it seems like most techs, even Ford dealer techs, are oblivious to the AsBuilt stuff beyond what's loaded via the PMI process in IDS. I've been diving into the AsBuilt and electronic side of things with my '13 C-Max lately and it's been a fun learning experience. I kinda like how Ford's set it all up. Universal modules that can usually be shared between Ford models and just simple AsBuilt bits to tell it how to work with each individual vehicle and trim level. Also fun finding little features to enable that Ford doesn't enable from the factory. :)
