Love your relaxing talking method of explaining things clearly ! 🤙🇬🇧

[@TamagoHead]

Great video! Thank you very much. I’m started to shade/tree brokanic again to slow down the aging process.

[@DavidMorales-nomadtec]

Great video. It helped me out immensely.

[@gabrielseaff487]

Good video and information. Thank you for sharing 😊

[@ramyswar296]

Thank you, this made things easy

[@alexandercahoulan6583]

always love the Acura videos. This is good to go over. Could save someone lots of $. Quality video as always dear sir.

[@mostefaikhemissi7491]

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

[@babelonchabalala1690]

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

[@derekwilson8011]

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

[@drbyers]

Exellent diagnostic tutorial. Easy to understand instructions and clear video helps noobs like me.

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..

[@PrairieLettuce]

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

[@DTUFINOPhotography]

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.

[@TheFlyingZulu]

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.

[@victoraigner]

Why not using just a jumper wire from the car battery? Thanks for the video

[@TheFlyingZulu]

This... lol.

[@ericaviator8869]

you did not discuss pressure switches ?? which Will tell computer to not send power to compressor, if out of toletance

[@tj8210]

the coil on the relay was good. but im pretty sure its pitted 25 resistance is way too high

[@MonicaPilcher30]

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 KZbin 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.

[@randrrcscorbin-tyler3998]

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

[@simonsuckie9906]

What is the link to get the relay with the switch

[@angieb825]

The can literally tells you if that isn’t moving then do not apply refrigerant.

[@freeboysofsummer1526]

so low air will cause the clutch not to engage

[@junioriii302]

No freon will cause the clutch to pause, so it won't burn out the whole compressor.

[@cameronvic1]

You didnt show which terminals to apply power to ,to engage clutch ,big mistake ,people have no idea
