Weirgly, my refrigerant depleted this winter in nyc.... not sure why, my Compressor Clutch is not engaging. I will get one of those bottle and add a little refridgerant and test but i'm taking my car to a AC pro to have it looked at after my testing.
Thanks .. now i know a bit more...... Question if refrigerent is low or empty will it stop clutch engagement or stop coil from activating? .... When i turn on AC the my AC fan runs but clutch does not engage.... It made a noise while ago then stopped completely.... Like a bearing noise.... I think clutch, bearing and coil went at same time.... Fuse is could ... I will check relay as last resort ... Then i will replace the whole AC compressor which is about $700 😢😢😢😢 .... Bummer
Any reason why not do 2 tests at once, as in jump the 2 high pressure switch pin sockets to send a signal to the PCM that the switch is in closed position (PCM thinks pressure is correct and will allow power to the relay for the compressor clutch), and then use some wires from the battery terminals to bypass the relay and send pwr directly to the clutch via the relaybosrd pin sockets - the foregoing after first determining correct pins on the pressure switch via continuity testing, and also the correct pin sockets on the clutch relay either by the diagram on the relay switch showing which relay sockets send pwr to the clutch, or by ringing out the clutch relay sockets to determine which 2 relay pin sockets pwr the relay switch and which 2 send pwr to the clutch). If clutch still not spinning, disconnect pwr coupling to the compressor, connect wired up alligator clips to that you have going to your battery terminals. If no clutch clicking sound when touching + and - battery terminals, clutch is toast. Realize that I’m spitballing all this.😮
If the pressure switch is faulty would the out cover plate still spin with the pully whether the air-con is on or off as I can't hear the compress clutch clicking?
I have a problem on my ‘05 Outback XT. The A/C fans always stay on high when the A/C is turned on. They never go down to low speed.. As a consequence the engine overheats slightly unless I drive the car on the Hwy and the temp goes down thanks to the Hwy airflow.. my A/C works fine by the way..
I have an intermittent problem with my AC not engaging as well as my fan sometimes not coming on either. Do you know what that could be caused by? The car is a 2018 Elantra.
Hi what if the clutch is engaged as soon as you start the car while the ac is off? Hyundai Accent se 2017. Refrigerant is full no leaks that I can see and relays are working
What if I have full fresh freon, new thermostat, new relay, new-ish compressor, but the clutch suddenly stopped working, then worked for a few hours, then for a couple days it did not engage, then suddenly it did again, cold ac, but then i shut it off, it stayed engaged, and lights on the controls stayed on until i turned the a/c on and off again?
Follow the a/x lines to a sensor, it's know as a pressure control Sensor. It engages and disengages your a/c clutch if the Freon pressure is accurate. Sometimes this sensor dies. Try to test with a multimeter or replace it
I have a 97 Honda CRV clutch is engaging no cold air smelt Freon while back leaking I don't know if my evaporator is leaking can I try a can of AC would stop leak or do you recommend that running out of options also took clutch off it looked worn down could it be slipping and looking like it's engaging ever ran into anything like that any information will be helpful thank you
2001 Jeep Grand Cherokee 4.0L I have issues with my A/C, will blow air but not cold air, added refrigerant as i thought that was the issue but it was reading full and no leaks as far as i could see, so I went down the RUclips rabbit hole and found out my A/C clutch wasn't spinning, so I checked the relay, that was fine, found out I could jump the low pressure switch to see if it'll spin and it does but still no cold air and when I went to check the pressure it read as low low.. I'm simply stumped... which reading is the right one? And how do I fix this?? Trying to donit myself.
Was sitting in Starbucks line, ac running, smelled a burnt smell, and ac stopped blowing cold. Replaced relay, started ac and something immediately started howling. Turned off immediately. Guessing the clutch bearing went bad and blew the relay?
Didn’t he just apply 12 V (or whatever that battery voltage was) in series to the existing 12 battery, effectively applying 24V at the coil? I would have thought you just need to short the relay terminals (the ones he tests for continuity)
Love your relaxing talking method of explaining things clearly ! 🤙🇬🇧

Probably a major leak somewhere... Usually the clutch. You'll need to find the leak, replace the leaking parts and then have the system recharged.
always love the Acura videos. This is good to go over. Could save someone lots of $. Quality video as always dear sir.
Exellent diagnostic tutorial. Easy to understand instructions and clear video helps noobs like me.
Will the clutch still “click” with the battery test method if I have no refrigerant in my lines?
Why not using just a jumper wire from the car battery? Thanks for the video
This... lol.
Good question I'm wondering that myself @@TheFlyingZulu
It might blow the fuse

Thanks for this vidéo. Sometimes the issue is the heat sensor of outside weather.

Sitting with same problem now. Been told its switch on the compressor and have to replace the compressor.
Great video Really appreciated that I’ll get it going for sure
May I ask you a question? What if the car air conditioner can work but is sometimes not working while driving?

Good video and information. Thank you for sharing 😊
what could cause the ac clutch fuse to blow every time I turn on the AC ? im getting voltage at the clutch connector
A shorting wiring maybe inside the compressor
My A/C relay is a 6 pin relays. Do you have any ideas with how to test those? It's off a 93 Miata
I have a problem on my ‘05 Outback XT. The A/C fans always stay on high when the A/C is turned on. They never go down to low speed.. As a consequence the engine overheats slightly unless I drive the car on the Hwy and the temp goes down thanks to the Hwy airflow.. my A/C works fine by the way..
you did not discuss pressure switches ?? which Will tell computer to not send power to compressor, if out of toletance

Hi what if the clutch is engaged as soon as you start the car while the ac is off? Hyundai Accent se 2017. Refrigerant is full no leaks that I can see and relays are working
whst if it doesnt fully disengage? i have an 04 jeep liberty. ac works really well but engine sounds rough when ac is off.
What if the clutch is engaging but the clutch discs are too worn out and make no friction? Is there a way to test that?
To be safe use a power probe lot safer and it will test relays too I found mine for 60.00 on amazon
Very good video. Thanks!

It engages and disengages your a/c clutch if the Freon pressure is accurate. Sometimes this sensor dies. Try to test with a multimeter or replace it
@@danielsumerix4419 Howdy, thanks for the reply. Turns out it was the connector for the low pressure switch
What about faulty pressure switches?
I have a 97 Honda CRV clutch is engaging no cold air smelt Freon while back leaking I don't know if my evaporator is leaking can I try a can of AC would stop leak or do you recommend that running out of options also took clutch off it looked worn down could it be slipping and looking like it's engaging ever ran into anything like that any information will be helpful thank you
Great video! Thank you very much. I’m started to shade/tree brokanic again to slow down the aging process.

Your pressure has to be read with the compressor engaged so when it was on and the pressure read low that was your actual pressure
What is the link to get the relay with the switch
the coil on the relay was good. but im pretty sure its pitted 25 resistance is way too high
Can you easily find AC relay on my 09 dodge 3500 I sure can’t ?
Your relay might be built into the TIPM.
Great video. It helped me out immensely.
Was sitting in Starbucks line, ac running, smelled a burnt smell, and ac stopped blowing cold. Replaced relay, started ac and something immediately started howling. Turned off immediately. Guessing the clutch bearing went bad and blew the relay?
Just change AC clutch
Thank you, this made things easy
so low air will cause the clutch not to engage
No freon will cause the clutch to pause, so it won't burn out the whole compressor.
The clutch can engage but the clutch can still be defective. It will slip and not turn the compressor.
You didnt show which terminals to apply power to ,to engage clutch ,big mistake ,people have no idea
Didn’t he just apply 12 V (or whatever that battery voltage was) in series to the existing 12 battery, effectively applying 24V at the coil? I would have thought you just need to short the relay terminals (the ones he tests for continuity)
If you look at the relay it shows you which two terminals trigger the relay. Should be diagonal from each other
The can literally tells you if that isn’t moving then do not apply refrigerant.
U said this was easy???
