My wife and I began a five hour trip in 100 degree weather when my AC began cooling only intermittently. Cooling lasted only a couple of miles at a time for several iterations then stopped altogether and blew hot. We stopped in at our local Toyota dealer who checked out the electrical, evacuated the system, added freon, and checked for leaks with no problems detected. We left the dealership with it blowing ice cold and traveled about five miles when it started blowing hot again. We ended up traveling the entire five hours with no AC. The dealership thought maybe a hose had popped due to the added Freon. I checked all the hoses and connections. No sign of dye or oil. Started the car the next morning and was amazed the AC was working. But as before, it only lasted a few miles. We were forty five minutes from a dealership who had no service appointments available. So I got on TH-cam and truly by the grace of God your video was first in the lineup. I opened the hood, found the MG CL relay and called O’Reilly auto parts. I drove it over snd they helped me replace the relay-AND IT WORKED! Thank you thank you thank you! Your video saved our vacation-and my sanity! God bless you sir!
Oh my goodness! I'm a 67 yr old lady that just fixed the ac on my Tacoma using your instructions....thank you so, so much!! This fixed it! It's blowing like a pack of ninjas now. I'm so happy.
You sir are a legend, 6 years after this video and its still relevant. Im in Australia, $17 relay Vs Hundreds to have mechanic check and fix... many thanks mate.
Wow! Thanks for your great help. I swapped it for fog light relay and it worked. Called our Toyota dealer, not in stock. Order for $90.00.Called NAPA. They had one for $19.00. Good enough for me. Thanks again.
Your suggestion worked on our 2003 Toyota Corolla, bought an AC Relay on Amazon for $10 (for 2) and now our AC is blasting like new. Thank you so much! You've saved us hundreds of $ if going to the mechanic.
I must make a comment you have done an excellent job with your communication. many people with accents I have a hard time hearing but you did a great job and thank you for the tip I'm going to do that in my troubleshooting process next
You sir are excellent! My 2018 Toyota RAV4 AC and heater would mostly blow 'half heartedly' and occasionally not at at all. Going over a speedbump at high speed would knock it and it would often kick back on, but still waver on blowing. I thought it might be a big AC/heater or blower fix. Turns out it was a $18 'magnetic clutch' relay! Thank you so much sir!
Thank you for taking us through this slowly most of us are not mechanics . If you watch a lot of videos they blast through it and you have to rewatch it over and over again 💪
That's exactly what happen to mine, it was working great, I turned it to max air and all of a sudden it went out and stopped blowing cold air, thank you for sharing!!
My Ac stopped working after turning off my tundra at my kids school. When I turned it back on my ac did not work at all. I changed the relay, for $15.00 . Thanks you just saved me trip to the dealer and at least $200.00 in dealer diagnostics fees.
I am another person who can verify this "trick". AC was working fine on my 2007 Tacoma with 230k miles. Suddenly stopped working. I reseated the relay, and suddenly I have cold air again! Imagine the $$$ people have shelled out unnecessarily.
my 2001 lexus lx470 had the same symptom, I just put in the new relay and it works. Thank you for saving me a lot money, I don't think the dealer or repair shop will tell me all I need is $8.00 relay.
This is amazing. The AC on my 2017 Highlander would only blow “ cool” ( almost warm ) air and I have had suggestions that the compressor needs to be replaced and another that the evaporator needs to be replaced. I have watched videos on TH-cam stating that the “:flow sensor “ on the compressor should be replaced ( Toyota doesn’t sell just the sensor you have to buy the whole compressor . Doorman sells the flow sensor for less than $30 ). Another video suggested the the AC Pressure Switch may be faulty ( a $184 part from NAPA ) . I am encouraged after watching your video that it may just be the relay which in Canada at NAPA would probably be about $30-$45??? . I’m going to try that out tomorrow.
I have a 2000 Tacoma Standard cab. The AC stopped working the other day suddenly. Prior to that it was working great. I just checked the fuse box. The only AC item there is a fuse called 10A/AC. That fuse is good. There is no MG CLT relay. Any recommendations welcomed! Thank you. Update: I took it to the Firestone service center. They said there was no more Freon or whatever the put into AC units these day. They replaced two gaskets and refilled the Freon... $230 later....
Thanks for sharing. It is really sad that the entire Auto Industry is so corrupt. I love the 80 & 60 series Landcruisers but finding parts became a treasure hunt. Now I am getting a 2011 Tundra and am not looking forward the dance one must do with maintenance upkeep. I can handle the Preventive stuff but your videos an prime example why I stay away from Dealerships, except for parts not available other places. I would bet 99% of Toyota Dealerships would have screwed the owner of your situation out of hundreds. Thanks for the lesson and helpful information.
I have a Toyota Sienna 2010 and the relay was not the problem. I tested it and swapped the horn relay. Besides, I could see the magnetic clutch engaging. I heard that without enough refrigerant the system will cut out. I used a recharge kit (EZ Chill) and now it's all good. So, I guess the system CAN just cut out from one day to the next just because of low refrigerant.
yes, but you will normally see A/C performance slowly down…..this video speak about case when it is ice cold, and next minute no A/C at all……good job fixing yours !
Yes, AC relays in Toyota are common to fail at around 200k miles in hot area. The symptoms is usually very simple, suddenly the AC blow warm air. Sudden change instead of slowly getting warm like AC lines leaks.
I am slowly working through the permutations to get AC working again. I was surprised that the refrigerant was not the problem. There was plenty of pressure. I tested the 10-amp AC fuse and replaced it. It blew right away, so I suspected a short. I will try this next.
Will check out your idea first thing tomorrow. But maybe i will also wake up to some hints too. Mt green button light comes on and stays on and it blows, but warm air. Any ideas? Low freon, meaning leak ???
Low Freon caused my Tacoma A/C not to cool that happened suddenly. Low freon causes condenser not to switch on. I checked the A/C fuse and relay which were good.
I remove the relay during the winter, hook it up during the hot weather saves wearing out the ac compressor, when you go for defrosting the front window you compressor engages to put load on the engine to speed up the warming of the engine and defrost your window faster
So weird! my 2016 Off Road, 4x4, all of a sudden just shut off. (green ac light went off and stays off). When I push the AC button on, I can hear it run then it shuts off, green ac light goes off. I checked the fuse and the replay, they are working properly. I had a friend come over and he said the compressor is running which is good news, however, he then assumed the refrigerant its empty so he was going to add freon but, his gage says the freon in full. That is where we are confused. Also its the 1234y NOT the usual 123A. Any insights? I want to sell this truck but I need to get this fixed first. We live in Florida. We do NOT have the $$ to have it serviced or even diagnosed at a local toyota dealership, they are way expensive.
I’m having this ac blinking light on a 2003 tundra which does not have the magnetic clutch relay. The problem is intermittent. When it happens I turn off vehicle and wait about 20 seconds and restart and ac works fine. Any ideas?
I checked the relay pins and it is okay. I even tried a new relay. What can I do next? The compressor will not turn on. The system is not leaking refrigerant. Does a 2005 toyota sienna xle have a high and low pressure switches. How do I test those? How do you test the clutch?
Greetings from brasil. Very helpful your video. I have a 2021 yaris, and i always keep the temperature at 23 Celsius. I am a taxi driver. But since the last cabin filter change my air conditioning has been eventually mal functioning. Which the temperature rising geting warm. Them i low on the display and is fine. But is annoying. Do you think can be the relay? Thank you
i'm going to try this. sears auto mechanic said i need a new ac amplifier and that unfortunately its discontinue so i have to hunt for 1 myself smh.... i have a 2009 rav4 sport and the ac blows hot out of nowhere.... ive even checked fan/fluids and its all good... its been doing it for a while now... hoping this works
2013 Camry came with a continuous operating compressor which has a flow sensor that has to open and the sensor is not receiving enough voltage to open right away until I have driven 3 to 10 miles, bad thing is you can't just buy sensor you have to replace the compressor, I'm still under warranty for 700 miles hopefully it won't cost me any money
My 2001 Tacoma doesn’t have anything labeled as described in the video as mg clt “magnetic clutch”. I see AC on one of the 10 amp and try replacing this.
Hi there awsome information, Hi Guy 4 years ago I bought a bargain Cruiser V8 2004 that just had a heap of head work. after getting it home for a week or 2 and the Cam sensor died got it back from the Mechanic then a few days later after a quick stop at the shops I started the truck and it stalled, I got it started but the idle was as rough. Can you help
Hi thanks for the video! could I test any other similar relay in the same fuse box to test it? I see similar shape and size but a different color??? Please help
My 2012 prius has this exact scenario. But my fuse box has no mg clt. The compressor is electric. Would the relay be anywhere else? Or maybe the inverter fuse?

If my ac light on my toyota turned off and now I have got air coming out of vents
I was looking for videos about this problem and your video was the best. Well explained. Thanks.
Bought a new relay for my 2013 Highlander at a local parts store for $7 and it worked!!! A/C is running like a champ. Thank you!!!
you are welcome
Your suggestion worked on our 2003 Toyota Corolla, bought an AC Relay on Amazon for $10 (for 2) and now our AC is blasting like new. Thank you so much! You've saved us hundreds of $ if going to the mechanic.
AC not working. Assumed no freon. Bought recharing kit for $47. Then saw this video & solved the problem. The relay cost $15 saved $32. Thanks!
Actually you lost the $47 you wasted on the recharge kit.
Emily Nicole Williams How do you know he didn’t return the ac recharge kit genius?
I found this video very helpful.... changed the relay and the AC works..
This saved me alot of money I would have spent with the mechanic
I just replaced my relay today and now good lord I fix the problem cold AC.... Thanks for your videos it help me save hundreds of dollars.
Thanks for your tip. My air conditioning works. You saved me a lot of time!! This video helped me a lot!!!
Awesome !!!

Glad to hear that…..
Recently bought a 2004 Rav 4 and the AC is totally dead. Gonna go give this a try. Thank you!

I have the same situation. The fuses blow instantly. There is plenty of pressure and refrigerant.
Will check out your idea first thing tomorrow. But maybe i will also wake up to some hints too. Mt green button light comes on and stays on and it blows, but warm air.
Any ideas? Low freon, meaning leak ???

I friggin love you, man! Saved me a trip to the shop and my A/C blows cold.
I like video .i am from VietNam.
Very Good Information, Many Thanks.
Low Freon caused my Tacoma A/C not to cool that happened suddenly. Low freon causes condenser not to switch on. I checked the A/C fuse and relay which were good.
This would be helpful if the 2006 Rav4 actually had the relay in the expected position...
A/C fixed thanks great video ! !!
Thank you very much did work afterwards
Thanking you sir for the information.
Thank you, I have a Prado 97, and that was the problem, after switching the relay, compressor kicked in inmediately :)
Thank you your a life saver.
Thank you, R134A @ 55 - no clutch - replaced relay - Aok

thanks for the video, I have a 2008 tacoma and this was the problem!
+JC king I'm glad I was able to help you….
Thank you!
I'm not melting any more!!
nice
There is no MG CLT relay in my fuse box. What is its equivalent for Toyota Prius 2013?
Mine either 😢
I remove the relay during the winter, hook it up during the hot weather saves wearing out the ac compressor, when you go for defrosting the front window you compressor engages to put load on the engine to speed up the warming of the engine and defrost your window faster
It's not just for warming the engine, It's mostly to dehumidify the air.
Where is the clutch relay on a 2010 corolla? Thank you
Thank you , you save me a lot of money

I have a 1997 Toyota 4Runner and there is no ac relay or clutch relay anywhere.
Hi there awsome information, Hi Guy 4 years ago I bought a bargain Cruiser V8 2004 that just had a heap of head work. after getting it home for a week or 2 and the Cam sensor died got it back from the Mechanic then a few days later after a quick stop at the shops I started the truck and it stalled, I got it started but the idle was as rough. Can you help
Nope, Flashing A/C light. Change relay, compressor, speed sensor, A/C Amp box and check for proper high/low freon readings, Nothings work to keep the compressor running? HELP!!!!
Thanks a lot. I have Toyota Sienna 2008. That relay was my problem.
Awesome…..
2012 same issue 👍🏻
Stan Vav
you are the best! cheers
Hi fantastic lecture
I have a 1998 4runner the ac condenser does not turn on. I can not find the ac clutch relay anywhere. Any help would greatly appreciated.
Excellent help.
hi Nice lecture thanks a lot
Problem solved. Thank you mate.
Gracias!!!! from PERU
you are welcome
Thank you Sir
Hi thanks for the video! could I test any other similar relay in the same fuse box to test it? I see similar shape and size but a different color??? Please help
Use the horn if same color and size
I would like to bring my Toyota Tacoma 4 cylinder to your shop . Where are you located
You deserve more than 💯 👍
My 2012 prius has this exact scenario.
But my fuse box has no mg clt.
The compressor is electric.
Would the relay be anywhere else?
Or maybe the inverter fuse?
Can you do a video on replacing the windshield wiper motor and assembly on a 2000 Toyota Tundra?
