I got a dose of humility today when I forgot that AC pressure switches have a built in hysteresis, closing and opening at different pressures. Of course they are built that way to avoid rapid cycling. The low pressure switch closes when pressure is greater than 49psi, allowing the compressor to turn on if commanded on. When the compressor starts up, low pressure falls, but the low side switch STAYS closed until pressure drops below 18psi, then opening to turn the compressor off. Then it stays open til pressure rises back to 49, turning the compressor back on. Duh! Came back for a refresher dose of ScannerDanner, thanks again.

Paul, great video. FYI...On an RSX I was troubleshooting there is a thermal fuse that is in line between ground and the compressor connector. According to Honda sites, this bi-metallic thermal fuse/switch warps with age leading to an open ground. It mimics a faulty clutch. It is a bear to replace the thermal switch since it is a bolt on component toward the block side of the compressor. The Acura blogs recommend bypassing the thermal switch to fully validate a faulty magnetic coil. I appreciate your excellent videos, and your commitment to high quality.

Paul you were very thorough on this repair. My Toyota Corollas' A/C clutch went out 5+ years ago and I know how the system works so I just did it the fast way to make a fast check by just going to the A/C clutch 2 wire connector and checked for power with my multimeter. I had my voltage at the connector and was switching off and on as I turned it on and off so I checked the continuity on the 2 pins on the clutch itself and it was open, so it had a open in the coil. Easy 20 dollar fix for my car and a 30 minute job and it's been working for over 5 years now. Since it was my daily driver, I knew the freon pressure was OK and I just went down to the source of the problem which was the clutch since it wasn't spinning. I was glad it was a easy fix for me but this is my way to diagnose a no A/C clutch. If I didn't have voltage or continuity, then I would work my way back up and do the other testing but I always go down to the source of the problem first.

Great video. But, one thing you missed - these compresors have thermal protector and it's located on the compressor housing. 12V from relay goes to thermal protector first and than to clutch coil. The thermal protector will have no continuity above 122 to 132°C (252 to 270°F). When the temperature drops below 116 to 104°C (241 to 219°F), the thermal protector will have continuity. However, if protector goes bad and always open, symptoms would be axactly as yours, having no current flow and suggesting open clutch coil. Field Coil Resistance on this compressors is: 3.05-3.35 ohms at 20°C (68°F). So to be 100% sure at your final conclusion, you should do your bulb test on wire after thermal fuse before it enters coil. Cheers!

Hi Paul: Watching your videos all the time, I learned so much diagnostic skills from that. so much appreciated, Thank you. I was working on a 2009 Mitsubishi Lancer with 2.4 L engine. This vehicle tow in to the shop, customer said the engine won't crank, all power are good including the battery. I feed power to the starter through one of the starter relay pin and the engine crank over and rule out the starter is o.k. And then I checked the starter relay (the same type of relay you are testing on this video). On the relay the loaded side I got battery power on one pin, and ground on the other, the control side I have ground on one pin, but on the other pin I have constant power (around 11 volts, one volt less than battery power) with the key on and the crank positions. Under this condition I assuming the starter relay should energizes and the starter should engage, but it is not. Further testing and found out it was the immobilizer key that causes the engine not cranking, The customer bring another known good key and the engine cranks and start right up. The question here is how the computer disable the starter relay if the immobilizer system is at failure, and why I will get constant power on the control side of the relay with key on, and when this happen, why the starter will not engaged?

Great video ScannerDanner. You enlightened me regarding the technology integrated into the system. Daughter's 06 Civic A/C Comp clutch not engaging. Verified good fuse, applicable relay (swap with another identical relay), good connections, tapped the clutch as noted in other videos, and finally verified approx 12 volts to clutch connection. Double checked everything (including line pressure). As a final step, I even tried Russ Kessler's method (it's acceptable in this case). Clutch still didn't engage despite tapping and fans running. I've come to the conclusion the clutch is shot. Unfortunately I don't have sophisticated equipment as you've demonstrated, but at least I've done what I could with the tools on hand (basic hand tools & a DMM. Again, you're explanations/reasoning is stellar. The vehicle has about 140K miles. Any idea how long the service life for these clutches are? After googling this complaint, it doesn't appear to be that uncommon.

So far it's the most comprehensive scanner I have seen for the price by a long shot, but as above I haven't tried it on very many cars yet, so I am cautiously optimistic, but a case of so far so good for me. It would pay to buy a cheap OBD extension cable to go with it as the unit is a bit bulky being cordless and this sometimes gets in the way of surrounding trim etc. Hope that helps.

Great video! The ground test at 37:45 would normally be done at the plug mounted on the A/c compressor, There is an exception on this style compressor because there was no plug at the compressor the plug was at the rad and the ground was bolted to the compressor housing. The reason why you would want to do this style ground test at the plug is there could be no connection due to a bent pin on the plug. The plug could have been damaged during another repair.

Hey Paul. You know I have been a big fan of yours for years now and i push your channel to many workshops i visit here in Australia for the shop owners/mechanics to learn more about diagnosing. Especially with scan tools as in my experience few know little about them being anything more than a code reader and if they did look at live data they would not know what to look for. When i get asked where can you learn this stuff i tell them to enrol in night classes or better still subscribe to your channel and get your book. So thats that part. For this though, the one thing that led me to follow your channel was speed and direction. You mentioned early in your videos how you hate flow charts. They make you do this and do that and waste valuable time diagnosing a fault. In this video i felt it was almost like following a flow chart. I think the best place to go would have been straight to the clutch to check power and ground and if they failed then go back to relays . I dont even think hooking up guages was required as you could have confirmed system presure was there by checking the tx valve presure switch. Had this been an instructional video on how to check AC electrical circuits it was a great video but it was a fault finding exercise and going straight to the end of the circuit would have told you everything. Hope my critisism is constructive. Still a huge fan.

Step 1. Check system pressures (always) Step 2. Check for power to clutch (couldn't get to compressor connector) You can switch up 1 and 2 but most of the time you'll be going back to the gauges anyway. So you find that you can't get to the clutch. You're in a gravel parking lot, with no wiring diagram or knowledge of the circuit your working on. What do you do? That's a rhetorical question. It's why I picked the direction I did. I systematically eliminated all possibilities before finally getting the van inside and up on the rack to check the clutch itself.

great video don't forget Honda loves to use a thermal fuse mounted to the body of the compressor wich is a common failure some times they put it in series with the compressor clutch or as a input to the ecm great vid

No thermal fuse that I could see on this one. Thanks for the tip

The scan tool can be rented from Auto zone for free. Except when testing the alternator. They will test that for you in the parking lot along with your battery.

Something people overlook is the compressor wont engage on many model/year vehicles if the pressure is too low. I ran into this issue the other day. Compressor fan was bad, blowing hot, etc. Checked all relays, replaced fan, compressor wont engage. It was 5psi low, added a drible left in the can and everything took off like it should.

Great diagnosis. Correct me If I am wrong here but couldent you have checked for continuity in the magnetic clutch? Maybe one lead on clutch wire through relay and 1 On ground.

Hey, Paul. Please, help me understand the RPM increase with the anticipated load, or the actual load. The pcm receives the RPM input showing an increase in load, commands the IAC to allow more airflow to stabilize the idle speed. Shouldn't the RPM drop instead of rising since the increase load has not been compensated for until the pcm the IAC to increase? Help me , please.

FYI .. The “lowly” Autel MaxiDAS DS708 does the AC Clutch ON test (on this vehicle), under the Inspection menu.

Is it best replace a clutch or measure the gap and adjust the gap if its too large a gap?
@soyeldiego48786 жыл бұрын
Thanks man for the informative video. I went old school by switching the relays and found that I have a grounded coil. Will be replacing the entire compressor since it has almost 200k miles. Question, should I also replace the expansion valves and condenser? The A/C system was working great until the clutch took a dive...

Another great video. A variable could be, if you weren't able to tap it into operation, is a thermal switch some manufacturers like to use including Honda.

You're a better teacher than myself, but I just feel the need to start at the consumer (A/C clutch) and work backards.

I just recently bought the ethos pro from snap on. it was like 1500 bucks. has bidirectional testing. does everything the modus, and verus does minus lab scope and troubleshooter. really great tool and have diagnosed several cars with it just using data pids and some basic principles I learned from you

RJ Martin Music $1500 and no troubleshooting or lab scope! Did it at least tell you what the number codes for all the manufactures signify?

Awesome video, I've been having trouble with my compressor clutch switch and been needing to replace it when I find time but what I would do is unplug and replug it repeatedly and wiggle until it finally kicked the A/C on. I then saw what you said about tapping it (which is probably common sense that I simply missed) so I decided I'd go give that a shot real quick and low and behold it did. I drive a lot and it'll be saving time by taking like 5 seconds as opposed to 10 or so minutes lol.
