Thank you @RB. You save me hundreds of dollars and hours of my time. I am mechanically inclined and have replaced plenty of ac compressor so I was already mentally preparing for that. I havent ran into any ac relay problems until now. I found your video and did exactly what you said. In my case it worked and I guess I am fortunate for now. I have a 2008 mdx with 150k for those of you wondering. Many thanks!
Andrew Gordon hell yeah I ran in to these so many of times I had one lady come to my shop she spent $700 at another shop and had no ac I felt bad for her I changed her relay and it was fixed I didn’t even charger her for diagnose and labor just for relay she been my customer every since but I do videos on all the cars with relays it helps I’m glad it worked for u and it common on most cars Don’t forget to subscribe also subscribe to my other channel here’s a link th-cam.com/channels/vqsPzqAZfVv_gjBYUFqNdg.html
Hey, man...thanks for the video. I had similar problems with a 2003 Toyota Corolla a few years ago, and purchasing/replacing the associated relay fixed the issue. Your video helped me to confirm it was likely the same problem with our 2007 Acura MDX and showed me which relay to check (basically the same in our 2007 model as with the 2010 model in your video). I tested by pulling another identical relay from one of the other relay slots and inserting it into the AC clutch relay slot, and sure enough the AC started working again. I picked up a new relay at a local auto parts store for about $7, and the AC on our MDX is back to normal. I love it when such an inexpensive, do-it-yourself text-and-fix saves the money I'd have to spend at an auto repair shop. Thanks again!
varuscelli yeah all honda Acura’s have this issue when ever u get no ac job straight to the relay with eyes closed! Thanks and subscribe
Driving around for 6 months with no working AC in my 08 Acura RDX. The AC would kick on and then turn off randomly. It pissed me off so much. I stumbled upon this video and 8 bucks later I have a working AC. Much better than the 1200 bucks I was thinking it was going to be to replace it. Thank you!
Sean Killam nice job! Saved heck of money and trouble there
😂😂 omg
Ex-muslim Atheist Rebel I’m guessing the excitement means this was quick fix for you !?!??
I’m driving from Atlanta to KC with my Sis. The AC on her 2012 Acura stopped blowing. 90°f out we were hot! I watched your video. Stopped at the first NAPA and replaced the fan relay and fuse. $14. AC 100% fixed! THANK YOU!
Rick Sinclair nice save of the day!!!! I always check these every ac job I jump on it first thing. Glad this worked please subscribe also subscribe to my other channel here’s a link th-cam.com/channels/vqsPzqAZfVv_gjBYUFqNdg.html
You deserve a drink my man. Thank you for the tip, worked perfectly. I switched out the relay and the 7.5 just to avoid future issues.

Thank you sir. Had taken my truck to repair shop twice and this did the trick. Saved me money!!
Nice job!!!!
Ty for taking the time to make this video; Saved me a huge repair bill!!!!!
Nice!!
I noticed that my acura mdx started to blow air not as cold as before, the rear didnt blow cold air at all, switched the relay and noticed there was a loose sound in the ❄ relay. Got a new one and problem fixed! Thanks
Nice job!!!!
Thank you so much with the lesson on reading the relays on the fuse panel lid. This fixed my relay problem!!
Nice fix!!! Good job!!! 👍
You the man! Thanks for the knowledge. This worked like a charm!!
Nice good job

I’m having same problem with my 2014 MDX AC blows warm air in few minutes cool air kicks in then work good until I shut the the car off I’m check this fuses today thanks for the video 🙏
I think you might have low Freon in the system I have had those few times ac works cold then gets warm it’s that once Freon come around it makes cold then the cycle is dry and it gets warmer mild and it repeats it def well try relay sometime those get hot and cut off ac and then kick back on
@@RBTheMechanic I’m going to add Freon see I appreciate for ur response boss.
@@sdinim8695 how ru going to add... usually I recommend complet service with ac machine lot of people add with can that usually makes it worst sometimes there’s air pressure so now u will have more gas with air pressure will act in similar way best thing is to recovered everything vaccume add oil and add correct amount
Gonna try this tomorrow, been hectic riding around this summer with no a/c lol
tarik k try this I get these all the time I jump on ac relay before checking anything else
Came across your videos.. thank you so much..god bless u

You welcome I’m always here to help!!
Awesome it worked !!!!!! 2008 mdx!!!!!! Thank YOU
Thank you buddy you are the men
I'm so happy to watch your videos, but I have a question. I have a 2019 AcuraMDX and I currently have 14800 miles on it. But today I found that the air-conditioning in my car is gone. I can feel some air-conditioning in the morning and evening, but there is no air-conditioning at noon. The aircon was working fine when I was using the car last week.I have run out of refrigerant in 4 years, is this a normal phenomenon?I have my hood open and when I turn on the A/C there is heat coming out of the front of the car and when I turn the A/C off the heat is gone. I feel like the machine is working.Can you tell me roughly what's going on with my air conditioner? thank you
You might have low Freon and it may need re charming donac service ac ac dye to trace for any leaks
The air conditioner was working when I started using the car yesterday morning, but it stopped working in the afternoon. Does this have nothing to do with the fuse?Also, is this normal use or it may be leaked in advance. thank you
@@davidliu1222 leak I can’t tell u cuz u need to have that check start with basics swap relay and fuse other wise it need pressure test and ac co press or tesing
Thank you for your answer, I make an appointment tomorrow to go to the car service station for inspection and repair.I hope this is just after normal use and not broken somewhere. Based on your many years of maintenance experience, do you think this is a normal phenomenon? thank you
2007 Acura MDX has front blower motor issues AC compressor works, blows cold air to rear of vehicle. Replaced the front blower motor, as well as the resistor. Will try replacing the relay and fuse as you suggested. I noticed you mentioned a AC blend motor that may be a part of the problem. Any suggestion?
Ok are u able to hear the motor run? Blend door is just a door that will open either hot or cold side but air will still flow. But there is a mode door motor which makes air go to defrost face or to feet maybe that got stuck at point where it was cutting all air. Anyways can u hear the motor run u can also open and pull out the cabin filter and put the motor on to see if it blows air u can even see if it’s spinning. Let me know if u can conform motor runs
Did this work for you? I have freezing air in the back and just ok air in the front
Do you where is the fuse located for the ac rear
It dosent or doubt it for separate fuse it same systm with extra blower. Do u get air in the back?
Thanks for the how -to on switching this out. Saved our bacon on our lengthy road trip. You deserve a 🍺 or two!!
RJ Senn LoL
I have a 2010 Acura MDX as well. I recently had a dash cam installed by a local shop and had it hard wired. It didn’t turn out well and now having issues with the car. For some reason the battery is draining and car won’t start. I noticed the heat/ac fan will not shut off when car is shut off. Any insight on what can be causing this issue?
U mean blower motor?
@@RBTheMechanic I think so. When I shut the car off and remove the key from the ignition, I still hear and feel air coming out of the vents inside the car where heat and air conditioner comes out from. I followed your instructions and replaced the relay mentioned in the video, but that did not work.
@@willsonherrera6142 well ur not sure if it’s on or not so u need to confirm that first
The relay of the relay nation is protesting the mistreatment of the relay🤣
I checked that fuse, seemed ok, didn't mess around with relay yet but have them confirmed and identify. Do you think this may solve my rear ac issue? front works fine, rear blows hot air. Wondering if there is any other relay for rear ac or this relay controls both
Patrick Langlois there might be read ac blend door motor you might have to look in to it the system is one for the whole car so if front blows cold rear is cold also the air door might be stuck on heat side
What if the ac compression comes on but comes back off right away, could also be the relay?
Well that depends on! If the systym full of pressure??? Or did it cut off and it didn’t build enough pressure? But do change the relay u never know!!!!!!
@@RBTheMechanic well it gets cold but then it stops and it start to throw warm air. And I checked the compressor and it kicks in but then it kicks back out. I will try to change the relay tomorrow. Or it may just need more refrigerated. Idk.
@@israelreynoso9006 that sounds like low refrigeration might want to reservice and add uv dye to trace leaks if any found repair it
YOU ARE AWESOME'!!!
MAY GOD / LIFE BLESS YOU WITH HEALTH.. YOU ARE ONE & ONLY .. MUCH BLESSINS.. GRACIAS
Thank you!!!
I have a 2006 Acura mdx and the A/C works fine through out my car but the heater in the front doesn't heat up but the back heater works fine. Any help 🙏
Check to see if the heatore valve works it’s u see hood close to fire wall connected to heatore hoses some times it’s broken it will not turn internally or the wire is off
Buenas tengo una mdx no enciende si da marcha sabes cuál es relay muchas gracias
Sorry idk Spanish but! I understand what the message was in this message anyways no problem glad this helped u out!
How do I take out the relay?
Needle noise plyer
AC issues with 2012 MDX. Stopped getting cool air into cabin in sections - first the driver's, then the passenger's and lastly the back. Got up next AM and AC was operational. Took it to dealer to have it checked as we were on a trip and really wanted the cooler air in the hot temps. Diagnosic check showed nothing as it wasn't acting up. Dealer replaced the relay. Drove it around town that day; it was fine. Headed out on the road the next day and after about 6 hours of driving, the AC went out again - slowly by cabin sections. We are no longer in the area of the dealership that worked on the AC. Any ideas?
Try the relay again but it’s wierd how it quits section by section it could be blend doors or the controls try letting it cool off that’s all you can do for now also see if the low side is cold u see hood. If it’s cold then ur system is working and making cold it could just be internal bleeding door problem
@@RBTheMechanic Talked to the local dealership who said because it was shutting down zone by zone, it wouldn't be the door. Do you have an opinion on this? Do you have an opinion on this? Thanks!! When you say "low side," what does that mean?
@@marywatt5116 well check the line u set hood u will see 2 lines that are aluminum the fat one is low side. If it’s cold the system is working and making come then it’s door issue
My 2010 mdx works but then after a while it stops blowing cold. Could this be a symptom of failure ?
I already replaced my pressure switch.
Change out ur relay. Hopefully that works if not then next step is to do ac service it could be low on Freon with air pressure worst
Come to worst ac compressive gives up making pressure with us rare with Acura MDX
So what if my acura mdx stalls out when the ac is on and I lose all power to the inside.
It could be due to loan on engine and rpm goes down below might worth do throttle cleaning
Try this out now. Let you know before i go to the mechanic. Lol
Hello! I have an 02 MDX. Read AC doesnt work I did what the video shows. But no luck. I notice the rear AC buttons/lights (orange lights) dont work. Maybe that’s my problem…. May I ask, what you would do to fix that? Probably a fuse?
Well fuse and relay are the basics check change both other wise u need to see if the system have freon pressure and check power to ac compressor
Thank you! The front AC is fine. So we will be checking the fuses for the back AC today 🤞🏼
@@vanessalam9029 ok back runs off the same system it might be the door acuator a that not letting cold air to back
You know what! Your video is on the checking the fuses! Thats what I need to do! My question was for a video after changing the rear motor! 🤦🏻♀️ Sorry!
You can probably tell, I am trying to fix this myself…. So I THINK the fuses and relays should be checked, before I go buying anything else. Haha
Also,
the orange lights that show the rear AC is on or off, doesnt work.. Can a blown fuse be the reason for that? Or the reason the back AC doesn’t work?
Thank you for your time!!
@@vanessalam9029 that’s always a step one check every and all fuses Justin case u miss somthing
Tengo la acura mdx 2005. Y los ventiladores no encienden. Alguien me puede decir que es. Andaban funcionando bien y de una no prendieron.
Sorry no Spanish
Great Video! I have a question about a 2014 Acura MDX seat memory issue. The Led indicators on the door showing Driver 1 and 2 settings no longer function and none of the 3 buttons respond when pressed. Seat, mirrors, steering wheel move just fine; Just the automatic memory function seems to have stopped working. I was looking for a fuse in the box you show in this video but had no luck. You wouldn't happen to know which fuse is for the Seat Memory system do you?
Seth Mellott I will definitely get back to you Monday morning once back in shop look it and and maybe will make a short video and link you I know it has memory seat fuse but I think it’s under dash will let you know Monday please subscribe
there are fused under hood my software dosent pin point it but finder fuse for power seats memory seat and ceck the fuse if fuse is good pull the fuse for about 3 minutes it will reset the system also check if the motors r working
@@RBTheMechanic Thanks, after a couple of hrs of checking fuses and an OBDII reader, ended up with nothing... ended up taking it to the dealership; they say the steering column needs replaced... $2K job!
Why do u have so many videos on this car lol jp . My mother in law has one of these trucks and her ac stop working she is bringing it over so I can check it tomorrow
Oh ok yeah start with checking the basic
@@RBTheMechanic thank you bro. She actually told me yesterday that they replaced the compressor last year and added Freon. She said no leaks from compressor so I’m thinking relay or fuse or both
@@EME4Mexicanos yup check pressure also u never know possibility leak
Does the relay have to be installed facing a certain way? Can you put it in backwards if you forget what way it was facing when you took it out
DEX 1000 it can only fit one way usually the legs are designed diff angles or it has a slot that will slide on. Cannot will not be able to install it wrong 🤗
My back AC on the mdx works perfect, the front AC blows air but it’s not cold air at all, (it’s hot air or just air from the engine idk). I don’t know if it’s a relay or if it’s the Air mix motor. Any answers to what might fix it
The thing is my ac works, its just it only works in the back. So if I’m getting cold air in the back that means the relay is working correct? So it’s probably something else
@@gonskii8168 ok play around with temperature knob put temp high low high low and also tap the blend door motor have some one help u it prolly start working I believe that’s what it is the blend door motor u can also unplug it take out the bolts and turn it by hand
@@RBTheMechanic ok one more question before I mess with it, there’s a blend door motor on both sides correct? One one for the passenger passes a bit of cool air but not enough. And the one on the drivers side is completely blocked off from cool air. My question is is their one on both sides and should I mess with both since they both are bad compared to the back
@@gonskii8168 I think this truck has 2. If u have dual temp control then it has 2 do u have buttons to change temp on passenger and drivers? If so then yup got 2
Did it blow but wasn’t just not cold? Mine isn’t blowing cold wondering if it needs refrigerant
Herakles dose the ac compressor turn once u do this if it dose touch the fat act line to see if the ac is making cold if compressor turns and ac line is not cold or very little then u need freon
Hi, When you say the AC was not working what do you mean exactly? Was the blower working, was it blowing hot air or nothing at all? I have an issue where the blower is working but the air is not cooling. What do you suggest for that?
J Martinez J Martinez yes the blower was working blowing hot air check the relay and fuse it’s very very common on the Acura’s and Honda’s after that if it still don’t work check if ur system have r134 in the system
@@RBTheMechanic Thank you for your response. It was very helpful. Best of luck to you.

My 07 acura still compressor not spinning relays are ok
Check pressure and power to ac compressor and how did u test ur relay?
@@RBTheMechanic i replace them and the fuses but so i need to check the 12volts on the connector to see if its getting power and if its fine then i need a new compressor?
@@rendiix4269 swap the relay
@@RBTheMechanic yea did that too with the same one you did and nothing happened then i replace them brand new ones and nothing
@@rendiix4269 check ac pressure ? When u out ac on dose radiator fans come on?
Thanks this works

What about if your ac work for a lil then doesn’t work but I turn the ac off for like 30 minutes n start working again n 30 minutes later stop working??
Did you ever found the solution I’m having same issue
I'm having trouble with my SH-AWD. Power only going to the front wheels. At the same time, the AC blows but not super cold ❄ as usual. Relay??
Matthew Lucas no relay would cut the ac completely you might be low on Freon ... also check to see if both radiator fans work I have had car that only one worked and ac wasent cool as before
About the other power trouble please explain to me more specific
@@RBTheMechanic no the AC problem is intermittent. And it coincides with the sh-awd not functioning
@@RBTheMechanic the light comes on for sh-awd. And when I look to the power distribution to the wheels, only the front wheels are getting power. Again intermittently
Matthew Lucas any codes?
I have a question regarding no power to the blower motor. I’ve changed the relay and the fuse but still no power. A friend suggested changing the resistor for the blower motor. Am I missing a fuse somewhere that’s critical to check before advancing with the resistor?
Christian Flores put the blow on full speed meaning on high dose it work? Usually full speed by passes the resistor try this and let me know
RB The Mechanic am unable to check variable speeds due to the climate controls being controlled through head unit. The head unit asks to check disc(Have looked into it and requires an updated disc). Is there a way to check the resistor for functionality?
Christian Flores try replacing it checking is too hectic rather just swap it
Replaced resistor and no power to fan... guessing it’s the fan?
Christian Flores your saying there’s no power to the fan if there’s no power replacing fan will not make it work
Hey hoping you can help me out. I have a 2010 Acura MDX. All of the sudden at the same time the turn signals dont work but hazards do. The AC only blows hot air and my doors wont lock but the truck wont unlock. HELP ME please. Thank you!
Mrz Raqui all these problem happned at the same time... check ur relays for ac but just a question for u did u have heavy rain in ur areas 🌧
@@RBTheMechanic Yes all at the same time. And yes we had a very bad thunderstorm. It was pouring. It actually even set off the alarm which never happened before.
I will definitely try what u said. Thanks again
Mrz Raqui ok check to see if there’s any water under dash by where u put foot feel the carpet usually somthing like
This is water in wires or body module
