I own a 2001 Nissan Frontier and I just found your video. My ac stopped working a long time ago and 2 shops were convinced my compressor was bad. I didn't have the money so i drove without ac for over 3 years. Last weekend my buddy who owned a garage for yrs started playing with it and we realized the negative wire to the low pressure switch had a bad spot. We ran a line and it kicked right on. Added 1 can of freon and it's ice cold. However, it doesn't kick on and off it stays on. Thanks to you i know where to investigate.

[@autopurlieu]

Remove your ac relay. If it still stays on, you ac clutch maybe stuff into the compressor. Not surprised coz it’s been sitting for 3 yrs. I hope you get it situated 👍🏽

[@TheDeathsentence123]

Awesome video. My problem is different tho. My previous AC compressor burnt up because the AC clutch stayed on all the time (when the switch was on and would turn off when AC was off). Figured since it has never been replaced, it finally gave out. So I replaced it with a new AC compressor. For a year it worked perfect and then the same situation started happening. Never fixed the issue again since the AC still works. Yesterday night, finally decided to work on it. Took the AC clutch apart and cleaned it up with sand paper. Cleaned all the sand that was in there. After putting it back together. It worked perfectly but then the AC clutch engage when it had too and then got stuck on again. When I turn the knob for the AC inside the car off, the AC clutch turns off. So after watching this video. I'm assuming is the AC relay that is probably bad and gives it power constantly when I turn the switch on. So I gotta swap it and try it out too. Is summer and I don't want it to burn up on me again.

[@TheDeathsentence123]

Or could just be the switch as well that is giving constant power to the relay.

[@autopurlieu]

Yah just check one area at the time to figure out which one actually give constant power . It’s sucks that happen to you

[@TheDeathsentence123]

@@autopurlieu Thank you!

[@TheDeathsentence123]

@@autopurlieu So I tried switching the relay just now like the 2 that you switched. Turned it off and on and works the same. Hit the turn off AC button inside the car and works the same. AC clutch turns off when is suppose to with the switches but when is on, keeps on running unless I turn it Off the system then it stops. So another faulty AC compressor, I presume? Switches function properly, switched relays and they work perfectly, cleaned the cluth and sanded it down, no shortage on wiring. The only thing left is the actual compressor then. Unless I replaced the AC clutch coil but then is gonna be more work and money if that doesn't work and the entire compressor is gonna have to be swapped.

[@omaralvarez945]

I am confused on why it would stay on if the ecm is the one that usually provides ground to a/c compressor. Wouldnt it still cycle on and off? Great video and you saved me a head scratcher.

[@cakepower1]

It just sends a signal to turn on or off, the relay is responsible for activating , relay has a mechanism that allows it to turn on and off, if the mechanism inside the relay fails it will not matter what the ecm wants.

Hi. I also have AC always on. Additionally the two radiator fans are always On too. Even when I just turn on the ignition the 2 fans start to spin. Did you have the same problem with fans in this video? 1) I tested all the relays. They are good. Ac clutch is good too. No OBD faults. 2) When I unplug Ac relay (as you do), Ac stops working but both fans are spinning. Fans only turn off when I unplug the Fans relay. I checked the connector of one of the fans, and there is ground even when car is off. 3) When I unplug the Ac connector then everything turn off (Ac and both fans). Thanks in advance

[@ralphlakindanum3019]

I got 2013 honda civic lx, and noticed that pipe is freezing up much and after 12mins drive im losing my AC, no cooling. I checked Ac clutch and relay found out that AC clutch not stopping even the climate control is turn off. Im sure that i am having same problem with this. Hopefully there is no more issue after fixing my climate control as i am having frozen pipe often. Thanks for the video anyway.

[@joerod7176]

I think you just helped me diagnose my BMW! On my car only the front vents will open but not the bottom or the defroster and my AC turns on and off at times or sometimes no power

[@autopurlieu]

What year model bmw? Scanner can probably pinpoint somewhere on ac problem you’re having

[@joerod7176]

It’s a 2012 bmw 535i , I scanned it and this is what shows…. Integrated automatic heating / air conditioning system ІНКА. So I noticed yesterday when I was moving the AC controls around it would turn off like the whole control unit would turn off unless I placed it in a certain way everything would turn back on, so I’m thinking it’s the AC control module that’s not working , And that scan also tells me which vent flaps are not opening, and I’m thinking it’s because of the AC control module possibly not working.

[@codybenoit394]

Hi. Ok my ac compressor stays on but i get warm air when stoped but driving i get semi cold air but when i go all the way to hot then back to cold it gets way colder. Fuses an relays must b good if it workin just compresser doesnt kick off an on. Now it is a 14 yr old one an i also removed the shime for the face plate to move n closer. Both fans work. I did put a used climate control switch with all the buttons about 1 month ago it worked perfect for the first 2 days either stopped are driving but then started doin the same thing then noticed compresser wasnt kickin off an on? Any thoughts would help alot thanks

[@autopurlieu]

I would start replacing with a relay first. Relay is relative cheap. Then it keeps doing it, make sure you have proper pressure inside the system. Always start with simple diagnostic before going further

[@codybenoit394]

I did earlier and still doesnt kick off an on. Ill get somebody soon to put guages on it and maybe change the high pressure switch.

[@autopurlieu]

@@codybenoit394 did you check if you’re getting power ? Start with electrical, it’s easy to figure that out. . Is compressor getting power ? Then do elimination process going back to the fuse.

[@codybenoit394]

Yeah ac runs fans work. It just gets warm when i stop but driving sometimes it doesnt get all the way cold. So when i move the hot and cold knob back and fourth it gets way colder.

[@autopurlieu]

@@codybenoit394 yah, get a small gauge. Pressure in the system change depends on the outside temperate . Might be overcharged or not enough pressure. Good luck brother .

[@cakepower1]

I just had all my freon escape from the relief valve from the compressor staying on consistently. Turned out to be the relay was stuck on, which also caused my battery to drain everyday and need a boost. New relay and i added freon that was lost and its kicking on and off with ice cold air 🥶 also the battery drain is also gone

[@woodchristopher93]

Can you show us what you would have done if that didn't fix it? I'm having a similar problem with mine. I've gone through all the same steps you have and my clutch stays engaged. I've even gone as far as to unplug the evaporator temperature sensor and it stays engaged. Not really sure where to proceed from here.
