The biggest problem in any trade is that the tradesman cannot "diagnose" the problem. I call them "parts replacers" because in many cases, that is what they do till the problem goes away and sometimes it doesn't even after you paid for all those parts. I am not an auto mechanic, but I have done ALL car, motorcycle and even aircraft maintenance since I was 13 (yup, I even flew the aircraft I worked on). So kids, stop texting and learn something here.
Very true,on my own opinion guys dont real understand electrical circuits that why they might almost change components which are not faulty at vehicle owners costs.
Hello Mr. Dan, greetings from the US. Nowadays I am a Pastor, but I had an auto repair 28 years ago. Closed the shop but still fixing family, neighbors, and sometimes church people's cars. I really enjoy your's expertise and your ability to communicate and teach in a clear way! I do understand how hard is to get your level of knowledge, it's needed many years of dedication and hunger! Congratulations and I think you would be a good Pastor/teacher of the Word of God if ever called! God keep blessing you.
I really laughed at the "I'm going all the way for you guys". I think we as technicians need a very high sense of humor to not get crazy with all this cars problems. I'm definitely subscribed.
I know this is a very old video but if that is your daughter OMG you can never deny that child she looks just like you my friend thank you for the knowledge you give us
Not only is this guy good he's a great teacher to boot. Just watched two videos and was really impressed, even Scanner Danner and Pine Hollow give this guy HIGH MARKS. Thanks for sharing your knowledge and experience. TheReaper!
You are the man DiagnoseDan!!!! you have a positive humble and kind approach to teaching!!!! very very powerful unique... i couldn't stop watching. not only do you have a happy customer you have lots of happy DiagnoseDan fans out here!!!!! Thank you for taking the time for us
Being a Field Service guy (Analytical and Scientific equipment) and as someone who is not and never has been into automotive repair business I am entranced by Dan's absolutely crushing videos and astonished by his uncompromising "no-soldier-left-behind" approach, superb technical prowess and solid expertise!Way to go, Dan!Have learned a lot already having watched just a handful of Dan's vids. The guiding principles of diagnosing the s..t out of any issue is the rock-solid foundation of Dan's surefire, thorough methodology that makes almost any other professional in this field pale in comparison to Dan. Dan has given me some valuable insights into how one should tackle any problem and successfully resolve it every time. Subscribed!
Excellent diagnosis Dan! Great visual explanation and breakdown procedures! It also pays to have the right test equipment!👍 Most mechanics wouldn't bother! Great job! 👍
People tells me that I am a very good electrical diagnostic guy, but man, you are the friction best. Your video came up on my screen so I watched it, and only true diagnosticians will go as deep as you did, as well as make it very plain for others to follow. My hat comes off to you brother.
Another great video! Your methodical technique reminds me of the Ford factory videos. Back in the day, Ford would rent a conference room at our local Red Roof Inn and have all the techs from several surrounding dealers attend the "Factory Service" classes. It was great! Ford would feed us dinner (bet they don't do that any more) then train us on the latest models and the "Factory Approved" repair techniques. They didn't pay us for our time, but no matter. The information I learned paid me back quite well. Keep up the great work!
Ha ha ha that sounds great, to bad they don't do that anymore! I'm not paying you for your time and i don't buy you dinner, but i'm glad you liked it anyway!😉
You are an excellent auto lecturer who teach the trouble diagnose more logicality. All of your customers will end up their repair only with replacing the exactly required spare part. Modern Technicians end up the repair job after removing 03 genuine parts with fake, finding the fault in the last one. Your customers are really LUCKY.
M an electrical engineer and love to see electrical system diagnosis...have been watching scannerdanner videos but after watching at yours , I have become your fan man....great job...calm and composed....
Thanks for the new video Dan, this is basically the same with any ground side control circuit and will help with understanding the process and shortening the diagnosis time!! Great instruction all around........thanks for taking the time!
what I find amazing is that this video received 380 thousand views and only 14 thousand people liked it! I feel your frustration on the stubbornness of people not wanting to hit the like button! What isn't to like about how detailed this video was! You not only showed the troubleshooting process but also showed how this compressor for the Ford A/C works, which I found extremely educating and useful in understanding how it operates! Personally, it helps me in the whole troubleshooting process to understand how something works! Thanks!
another great video about electric diagnosis. I like how you get very specific on the meaning of electrical measurements on components and wires. Your measurements on the solenoid remind me of how control relays behave which is very similar in that when not grounded have power on both sides of the coil, but will have power only on one side when the pcm grounds the control coil in the relay.
Dan's THE Man !! Just goes to show how too many forget the fundamentals and jump straight over into replacing parts... Shotgun approach is very bad, especially to the poor customer who has to pay for the incompetence.. Thank God for guys like you Dan, who educate us and teach us the RIGHT way.. Two thumbs up man !!
10:29 The thing held by the left hand is the reed valve assembly. FYI, this is what makes variable displacement compressors emit a low groaning noise when the swashplate is held for whatever reason at minimum stroke angle. The reed valves just begin fluttering about due to the very short piston travel, and the suction gas pressure oscillates very rapidly as a result, and the noise can propagate to the evaporator (and hence be heard from the vents) through the suction line (in variable displacement compressor systems a muffler is often found on it for this very reason). A lot of people complain about that kind of noise especially on German cars equipped with such compressors, but it's entirely normal as long as the variable displacement compressor isn't kept destroked due to a very low refrigerant charge, a faulty control valve or faulty control valve wiring or whatever abnormal reason.
great fix, thanks again Dan 👌 that's a common fault on most vehicles where vibration or pulling forces are an issue, specially with bad motor mounts or bad shocks (bad roads or bumps also helps out the possibilities on that issue) i have seen it in many times its very common on transmission modules too
As usual Dan, excellent video even though I do not have this type of AC system in my cars. I had the same problem where a connector pin was not fully snapped into the connector housing on my motorcycle. Sure enough, it was the pin coming from the kill switch to the electronic ignition module on my 1990 BMW GS which is why I noticed a slight hesitation while driving. I looked into the connector, saw a pin was very recessed, pulled back the rubber boot, pushed the pin forward and heard a nice "snap" as the pin engaged in the connector housing. Bingo...perfect! By the way, you have a nice Nussbaum lift. I had to settle for a MaxJax lift in my private home.
Unbelievable fix. Just goes to show that connector is of low quality. Pins in a connector normally don't just fall out. Brilliant- consise repair done with Military precision. Well done my friend.
Another Great video Dan! Loved the inner workings of the compressor & how the variable swash plate is controlled by the solenoid Oh & I got to learn about bias voltage as well, always wondered what that voltage hanging about was ( ha ha) I can honestly tell you I’ve learnt more from watching your channel over the past few months than i have from the technical courses I attend at a certain German manufacturer (I’m a 30 yrs plus tech) Keep up the good work I look forward to the next instalment:-)
I'd never thought of "variable" AC other than cycling the clutch - a variable angle swash plate is genuis, and really well demonstrated. The way you take the time to explain each step, AND what it means and go through the process each time, it's invaluable for hobbyists and professionals alike. Really love the way you work. Thanks so much!!
I get a kick from all these other shops making expensive diag calls and what do they tell the customer after replacing the parts and not fixed the problem? Dan you are on fire... Awesome vid I watch Scanner Danner also but the way you explained bias voltage.. I 👍
Thanks Ermal! For watching my video's, i hope you like them. I don't know what shops tell their customers, what i do know is that it isn't always easy and everybody can make a wrong call sometimes.!
Dan, your diagnostic skills are top notch. For many mechanics, it's easier for them to just throw parts at the problem. That benefits the mechanic and the shop, but is terrible for the poor customer. I salute you sir!
Outstanding that you actually make the effort to find faults with connectors. That is the biggest problem with a lot of mechanics. They are into replacing components because it doesn't require much thinking
Thanks a billion times Dan, i came a cross a car with the a/c solenoid which i kept confusing for a pressure safety cut off switch, the tutorial of the slung plate made me understand how the design works and i was able to fix the problem. Previous mechanic replaced the compressor 3 times and ended up with the same problem
It would seem that when that wiring harness was assembled that particular pin didn't get pushed in all the way and locked into the connector. It initially made contact to the other side but eventually over time it worked its way loose. Basically this was an assembly mistake at the factory that didn't show up immediately.
I've been watching a lot of video in the internet. So far your videos are the best. You explained very throughly and easy to understand. You speak very slow. You let your audience understand it very well. Keep up the good work.
Great video Dan, thanks for sharing. Who knows why that pin wasn’t seated properly. Thanks for sharing w/ us the insides of a variable compressor. Again, great video. Thanks for sharing.
I’ve been working on cars since the 80’s and thought the new stuff was out of my league, but with a decent obd2 scanner and a good basic knowledge you have shown people that they don’t have to be held to ransom by main dealers, you sir are both humble and probably the best auto tech I have seen👍
Hi Dan, I went to college for my NVQ Level 3 and Diploma in vehicle repair and I have to say, of all the excellent teachers we had I reckon you would have been perfect for the job. The way you explain things in a simple and easily understood way for beginners is excellent. Love your videos so much! All the best, Dan from the UK.
had my first encounter with bias voltage on a 2007 ford bantam (SA model) idle control valve (3.6 volts at the connector disconnected), had to call a PCM on that car no pulsed ground from the ECU, even on startup considering intentional driver shutdown. customer couldn't afford the repair so is driving around with a jimmied throttle body plate to idle. It still running up to today like that.
The best video ever!! You just got a subscriber for life!! I like the way you explain and show with diagram for beginners not talk about it for seasoned techs. You know your audience. I’ve never open a a/c compressor and that was awesome to see how it works. Thank you so much.
Excellent job Dan , I am very happy to watch videos like that and trace the fault with you , you have patience and skills to fix problems to save your customers’ money .
Dan. Thanks to you I finally understand what bias voltage is. If there’s something I live about the automobile field, other that learning new things everyday, it’s electrical diagnostics. And this will really help me save time in future diagnostics. Thanks again.
This channel has some of the most informative electrical testing I've seen, its incredible learning more about wiring and doing these types of methods to isolate the issues, from VW to Ford this is a great channel for any issues, recommended the BMW door handle no start video to new viewers. Thank you Diag Dan
I thought I wouldn’t find this one interesting but I found it fascinating lol ! I watched every second of it even though I don’t own a Ford and don’t understand what’s going on . Very clever and entertaining man 👍👍👍
Very instructive Dan!! I have an Ecosport Kinetic 2014; suddenly the AC wouldn't throw cold air anymore. Apparently the clutch was not engaging, but this I couldn't see by myself it at the beginning because of the position of the compresor in the engine housing. I checked all the fuses and the relay and they were ok. I scanned the systems with a USB ELM interface connected with my PC and FORScan software. No DTC were reported. I also runned tests to see if commands where activated when the AC was ON; all was ok. The pressure of the compressor lines where at 780 kPa (113 psi) when the engine was cold, which at least meanned that there were no leakage; but as the test elapsed time growed the measured pressure increased up to 1070 kPa, no depending much on the AC activation switch. At first this puzzled me; but then I understood that as the compresor was not working, the increase of the temperature of the engine would heat up the AC system increasing the pressure of the lines. I took the vehicle to an AC workshop, and they told me that in fact that the clutch was not engaging, possibly because of PCM failure. I went back to home, and started watching youtube videos until I got to this one. I made further tests, removing the AC relay to see the voltages, and I concluded that the problem might also be in the same connector you showed in this video. The said connector in the Ecosport in fairly accessible. It was all dirty and unprotected from the environment. I just only moved the cables a bit and Voila! the AC worked again!. Pretty sure I saved myself a lot of money. Thanks Dan!
A superb unhurried explanation of everything, making complicated things simple. Every technician and car owner should watch all of your videos, even if they think they already know it all. Most technicians Ive met actually have an appalling lack of knowledge and simply replace things at the customers expense. iI I owned a garage I would make it mandatory that all my employees watched every one of your videos. Very well done with just the right amount of humour.
In deed you're right by saying this system might be different in other models because I remember I saw Ivan's (Pine Hollow Auto Diagnostics) video about a variable AC compressor belt pulley failure and the belt pulley of the AC compressor was not electro magnetic actuated but it was a fixed part always rotating while this one you're showing here has a electromagnetic controlled belt pulley like the regular old AC compressor models, but that is the only difference to the one on Ivan's video. Diagnose Dan You're amazing! Your teaching skills are wonderful! I feel like I'm ready to service this type of AC compressors already! Thank you very much! You have a wonderful family!
Electro magnetic actuated clutch saves some fuel and also saves the compressor from total seizure (and the AC system from what a seizing compressor pumps around too) if refrigerant charge is lost, compared to clutchless...
First time I check this site and I am suprised how good explaination you give. As a refrigeration technitian, that was an amazing fix. Thanks and keep doing more!!!
Ha ha, ok well these cars i have watched you fix would drive me nuts, trying to get on top of them! You do a great job, your services will ALWAYS be in high demand with modern cars!
Hey just want to say thank you. I had a jeep few years back. Crank no start 3 garage and still no fix. So I towed it home and started looking at wire diagrams. I found the problem after much money spent. It was a short to ground. From that day forward I been showing people not to throw parts at stuff and so many places do that. They get new computer and on and on. So I'm starting my own place to show people and help people save money. You and scannerdanner change the world one video at a time. You and him should get together and make a video on a really really tuff crank no start that shop says needs computer. Thank u
Great explanation of a common sense, step-by-step approach to diagnosing an issue in modern vehicles, particularly the explanation of bias voltage and its use in diagnosing circuits controlled by the PCM, and the value of the Power Probe in this process; i.e. a great use of Occam's Razor to find the simplest solution to a potentially complex and expensive problem. I really appreciate your taking the time to make this video on a Saturday, realizing that you probably had to make it in multiple languages for your different audiences. I appreciate your showing and explaining to us the swash plate method of controlling the pistons in the compressor, something I learned the hard way about a month ago.
NO PARTS REQUIRED that was awesome, Dan! Love the teardown and explanation of the variable A/C compressor too...very cool video :)

Good troubleshooting, I admire the way you work to find the actual fault, and not jump to conclusions. Lovely fan club too.
Very informative video. I learned something new. And your English is very good :-)
Thanks i'm doing the best i can😀
Dan you are the funniest guy in automotive if not the most talented. You are one of most talented technicians I come across on the Tube.
a ford connector with a fault, who's ever seen that before lmao, ford connectors are junk, great vid Dan.
🤣🤣 Thanks Chris.
chrismechanic B I second that Chris Ford wiring and connectors of late are very poor
You doing great. Psalm from liberia 🇱🇷
hitting like before you get angrier, I almost saw the HULK. lol
Ha ha, just a little fun before going on with the serious stuff🤣🤣
had my first encounter with bias voltage on a 2007 ford bantam (SA model) idle control valve (3.6 volts at the connector disconnected), had to call a PCM on that car no pulsed ground from the ECU, even on startup considering intentional driver shutdown. customer couldn't afford the repair so is driving around with a jimmied throttle body plate to idle. It still running up to today like that.
The best video ever!! You just got a subscriber for life!! I like the way you explain and show with diagram for beginners not talk about it for seasoned techs. You know your audience. I’ve never open a a/c compressor and that was awesome to see how it works. Thank you so much.
Damn Leon beat me to it!
Hahah too slow
You are the first Ivan! Leon had a preview. You must have been up early!
This guy is the real deal!
Another excellent video, Dan and no parts required.
Love it when i can fix something without using parts, unfortunately this isn't always the case😉
Learned alot from u Dan, thanks
Thanx, i always like it when people learn something out of my video's!
What a brilliant explanation of how the compressor and circuit works. Exactly at my level of understanding. Dan, you are the man. 👍
Great job Dan! I'm glad you have been taking the medication that the psychiatrist prescribed. You are able to focus much better. 😁
Somethimes i forget to take those pills Glen and strange things start to happen🤣🤣.
@MrLouthguy 🤪
Excellent job Dan , I am very happy to watch videos like that and trace the fault with you , you have patience and skills to fix problems to save your customers’ money .
If I ever find myself living near you, I’m submitting my job resume to you
😀😀😀👍
Recomended for you

Only bad thing is I've watched all of your videos already cant wait for another one
Working on it😉
@@Diagnosedan thanks a lot you do a great job awesome content keep it up and thank you for taking the time to do it. Am a big fan of your work
Don’t you hate it when customers bring you a car with an empty petrol tank?
I do, but fortunately i didn't have to testdrive this one!
This.
we just fill it up and charge them extra
If you are going to do some work inside the tank, you can bet the tank is full:)

Dan. Thanks to you I finally understand what bias voltage is. If there’s something I live about the automobile field, other that learning new things everyday, it’s electrical diagnostics. And this will really help me save time in future diagnostics. Thanks again.
This channel has some of the most informative electrical testing I've seen, its incredible learning more about wiring and doing these types of methods to isolate the issues, from VW to Ford this is a great channel for any issues, recommended the BMW door handle no start video to new viewers. Thank you Diag Dan
Diagnosed Dan made me smarter again.
Ha ha ha that's a good one!
I thought I wouldn’t find this one interesting but I found it fascinating lol ! I watched every second of it even though I don’t own a Ford and don’t understand what’s going on . Very clever and entertaining man 👍👍👍
Ha ha Thank you!😉
This young fella KNOWS his stuff! Brilliant.
Very instructive Dan!! I have an Ecosport Kinetic 2014; suddenly the AC wouldn't throw cold air anymore. Apparently the clutch was not engaging, but this I couldn't see by myself it at the beginning because of the position of the compresor in the engine housing.
I checked all the fuses and the relay and they were ok. I scanned the systems with a USB ELM interface connected with my PC and FORScan software. No DTC were reported.
I also runned tests to see if commands where activated when the AC was ON; all was ok.
The pressure of the compressor lines where at 780 kPa (113 psi) when the engine was cold, which at least meanned that there were no leakage; but as the test elapsed time growed the measured pressure increased up to 1070 kPa, no depending much on the AC activation switch. At first this puzzled me; but then I understood that as the compresor was not working, the increase of the temperature of the engine would heat up the AC system increasing the pressure of the lines.
I took the vehicle to an AC workshop, and they told me that in fact that the clutch was not engaging, possibly because of PCM failure.
I went back to home, and started watching youtube videos until I got to this one.
I made further tests, removing the AC relay to see the voltages, and I concluded that the problem might also be in the same connector you showed in this video. The said connector in the Ecosport in fairly accessible. It was all dirty and unprotected from the environment. I just only moved the cables a bit and Voila! the AC worked again!.
Pretty sure I saved myself a lot of money.
Thanks Dan!
Your logical approach is second to none
A superb unhurried explanation of everything, making complicated things simple. Every technician and car owner should watch all of your videos, even if they think they already know it all. Most technicians Ive met actually have an appalling lack of knowledge and simply replace things at the customers expense. iI I owned a garage I would make it mandatory that all my employees watched every one of your videos. Very well done with just the right amount of humour.
You are very thorough and clear in your explanations. Thank you. I enjoy watching your videos.
Glad you enjoyed my video!
In deed you're right by saying this system might be different in other models because I remember I saw Ivan's (Pine Hollow Auto Diagnostics) video about a variable AC compressor belt pulley failure and the belt pulley of the AC compressor was not electro magnetic actuated but it was a fixed part always rotating while this one you're showing here has a electromagnetic controlled belt pulley like the regular old AC compressor models, but that is the only difference to the one on Ivan's video. Diagnose Dan You're amazing! Your teaching skills are wonderful! I feel like I'm ready to service this type of AC compressors already! Thank you very much! You have a wonderful family!
Thank you so much for your comment! 👍👍
Electro magnetic actuated clutch saves some fuel and also saves the compressor from total seizure (and the AC system from what a seizing compressor pumps around too) if refrigerant charge is lost, compared to clutchless...
First time I check this site and I am suprised how good explaination you give. As a refrigeration technitian, that was an amazing fix. Thanks and keep doing more!!!
WOW. Dan makes it look so easy, just love to watch him doing it, together.
20 thumbs down. What were people expecting?.dancing scantily clad women . Good job Dan . Interesting and informative again and again
Thank you Sir😊
You will never be short of work as you will have a good reputation. Thank you
Awesome job with the exploded view of the compressor 👍
Binge watching James?🤣🤣
@@Diagnosedan Sir yes Sir 😂
You are not alone sir . We watch you .and learn a lot from ur work and tips n tricks to diagnose 👍👍👍👍 thks for ur work sir .Allah bless u👍👍
Ha ha, ok well these cars i have watched you fix would drive me nuts, trying to get on top of them! You do a great job, your services will ALWAYS be in high demand with modern cars!
Break the moders cars down to little pieces and they are not that complicated anymore!
Dan, you are a genius, I like the way you took us along during the whole Diagnosis process. i appreciate all your effort.
Hey just want to say thank you. I had a jeep few years back. Crank no start 3 garage and still no fix. So I towed it home and started looking at wire diagrams. I found the problem after much money spent. It was a short to ground. From that day forward I been showing people not to throw parts at stuff and so many places do that. They get new computer and on and on. So I'm starting my own place to show people and help people save money. You and scannerdanner change the world one video at a time. You and him should get together and make a video on a really really tuff crank no start that shop says needs computer. Thank u
Dan's good, as retired auto electrician I love the way he explains step by step. Also with humour photography is excellent.👍👍👍👍👍
Great explanation of a common sense, step-by-step approach to diagnosing an issue in modern vehicles, particularly the explanation of bias voltage and its use in diagnosing circuits controlled by the PCM, and the value of the Power Probe in this process; i.e. a great use of Occam's Razor to find the simplest solution to a potentially complex and expensive problem. I really appreciate your taking the time to make this video on a Saturday, realizing that you probably had to make it in multiple languages for your different audiences. I appreciate your showing and explaining to us the swash plate method of controlling the pistons in the compressor, something I learned the hard way about a month ago.
