Hey bro, glad to see you out there pursuing your passion. Wish you were here to take care of my sick jaguar. Praying for you and your family. Stay blessed Pastor Al .
All Hondas/Acuras since the 90s have bad A/C clutch relays. Most of the time the relay fails to close but like you said sometimes it will fail to open/weld closed. And because the power that feeds the switching side of the relay is constant 12 volt, it will drain the battery if left sitting a short time with the engine off. The fans too are junk on Hondas. Often times failing before the vehicle has 50K miles.
Great job troubleshooting the problem and remaining calm while doing it. So many times, a lot of techs lose their minds and make the problem worse. Please go back and review your camera work you picked up something interesting and I don't think you caught it. When you were shining your flashlight down towards the A/C pump and was trying to get the clutch to come on you filmed magnetic partials bouncing around on the lower piece of plastic. That is a great indicator of a pump that's getting ready to fail, those are the particles from the motor or clutch coming out and being distributed by the magnet poles on the clutch. Just trying to help a fellow tech, though you seem proficient already. Thanks for sharing!
New subscriber and I own a 99EXL accord with only 62k miles on it. I just changed the cabin air filters and yes they are in correctly but I noticed the middle A/C air outlets have very little air flow. The driver and passenger out let’s are fine. The A/C also does not feel as cool need to check it with a temp gauge. The scanner says all switches open and close properly. I’m definitely going to check the system your way. Great video and thanks for sharing. 👍. Artie. Any inputs greatly appreciated
From what I've gathered the Mitsuba relay (39794-SDA-A05) is an improvement over the Omron. And, the Denso (39794-SDA-A02) is an improvement over both the other two.
Hey there, I had the top of a radiator replaced after we found it had a leak and caused the Honda fit aria to shut off in traffic. The next day the ac stopped blowing cool air. Any idea what the problem could be?
Assuming there is no leak in the AC system, for AC compressor not working issues, there are really two common problems: either the AC compressor relay is bad or the AC clutch relay/fuse is bad. He found the obvious problem with the AC compressor relay despite the fact that it clicks but checking it with the multimeter confirms it is a dead relay. I had a similar bad relay on my older Honda Accord AC and it cut out the AC during a summer trip, such a bad time. What I did not expect he found was the two worn radiator fans! The vehicle only has a little over 100K miles on it and both fans already worn out. I never had any radiator fan worn out on any of my vehicles ever! That speaks very poorly on the build quality on these cheap sub $20K Honda Element! These cheap Honda are made with cheap parts to keep the price low, don't expect it to last like the Honda CRV or Honda Civic! I'd do something very differently to check on these fans: never use your fingers to touch the fan blades, ever, unless you want to lose one or more fingers. These blades are sharp and if these fans have enough contacts, they could spin up and chop your fingers off your hands! User a screwdriver instead to touch it and nudge it because they could come on at any time when the thermostat tells them to run. There are other problems that cause the vehicle to stop sending power to the AC compressor but you will have to check on those only if these two relays are confirmed fully functional.
quick question, if I put some freon in the system and it only blows cold air for a week is it most likely a leak? (2007 acura tsx) I tried putting the product with UV dye but I could not located a leak. AC worked really good with the recharge, just didnt last long.
2 common areas on Hondas/Acuras for refrigerant leaks is the compressor or condenser. Look for areas that have accumulated a lot of dirt and oil staining. That is likely where the leak will be.
Honda CRVs and Acura TSXs had a huge compressor design flaw where liquid refrigerant was migrating back to the compressor and because a liquid cannot be compressed, the compressor would detonate catastrophically. They extended the warranty for them but oftentimes it was still outside of the coverage leaving the owner to foot the bill.
Hey my 03 accord has good relay fuses plenty of pressure fans run indoor blower checked pressure switch and still no compressor ot just stopped suddenly
I got a 2000 Nissan Altima my clutch doesn’t engage it has new ac compressor in it and it has refrigerant. When I jump start the compressor it still don’t blow cold. What you think the problem is ?
My son drives a 2009 Jazz. It`s a greatcar, but the A/C clutch is dead, emitting a loud noise when driving. Can you remove the belt to kill the noise and still drive the car? Obviously the a/c won`t work, but we`d change the clutch at a later stage. Thanks!
@@turbineking7154 thanks, but do you need the belt? Removing the belt would kill the noise until we can change the clutch, right? And the car would still run, but without the noice and no a/c obviously?
I got a 2011 TSX with no a/c. A/c compressor isn’t coming on and the condenser fan isn’t coming on. I bypassed and jumped the a/c relay and the compressor came on but when I swapped it with another same sized relay it turned back off. What do you think it can be
@@FixItPhillip I fixed the leaking valve and got the a/c system recharged by a professional. But a/c compressor or condenser fan don’t come on. The compressor only turns on if you bypass the relay
@@KR-uk1mz wired in series of the compressor is a thermal protector. It checks the temp of the compressor but if it’s malfunctioning it’s not gonna turn on the compressor. I just jumped the thermal protector, works perfect now brotha
I’ve got new relays, new compressor pressure is right, switch is working, recharged too, fuses are good too and i still don’t have AC. Any ideas on what the problem could be?
So something similar happened to my dads ford truck and it turned out to be the blend door actuator. It’s supposed to change the temp, so i would look into it
remove omron relay take case off clean contacts with light emery cloth replace will work inrush current arcing on contacts causes this i can design and forward an inductive fix to this issue @@cwilly8888

Thanks for the informative content. Are you open to doing any product review that related to Auto led lighting? We just emailed you for inquiring an product review. Hope what we offer could be a part of your fantastic content.
Come on, NEVER must I say NEVER put your finger in a fan to test or try to get them to spin. What if it was just a dead spot and it took off like they can do. You'd have no fingers. Please don't show this stuff to DIY ers, you are promoting a accident. Even a rubber hose could be used to tap it. But if it starts that could be thrown at you. Disconnect it and test it with a meter.
That was awesome how you diagnosed everything. Makes me look at things different.

@@dannyhefnerdon’t ask the person above a question, they’re an idiot. yes, if it only lasted a week you most likely have a pretty bad leak somewhere

On 2019 - 2021 and maybe 22
Civic there's a recall on the condenser rotting out, you won't get a letter from Honda but a warranty for 10 years
In my case, the AC stops suddenly. I replaced the relay, new gas, and nothing works. The solution was to replace the expansion valve, and that's all.
Hey my 03 accord has good relay fuses plenty of pressure fans run indoor blower checked pressure switch and still no compressor ot just stopped suddenly
What does it mean if it's not clicking I don't think mine is.
Couldn't you have figured out if relay was bad by just swapping it with a known good relay? Like h0rn relay?
He is teachings us how relays work. Sometimes you just need to know how things work for you to figure out how to fix it.
Thanks Ill have to check this on my 22 CRV .
Same! If you find a solution Can you please come back to this comment
Thank you for the video 😊

No, you need the compressor to support the belt
@@turbineking7154 thanks, but do you need the belt? Removing the belt would kill the noise until we can change the clutch, right? And the car would still run, but without the noice and no a/c obviously?
There no other way to test relays?
2008 Honda Odyssey HVAC Blower Motor Resistor, Front by Airtex was my problems after all the relays
Great information, so the Amazon link is the Matsuro relay? What fans are good? Also what fan swich is good?
Hi was wondering what the 'upgraded relay' number was or what you were calling it? Video was blury for that image.
Should be a link in the description for the relay
@@FixItPhillip duh, I should have checked. Thanks for the video and good job.
Actually, you say " I remember the upgrade to a Mitsub???XXX Mitsubishi ?? and you happen to have one." You only have link for OEM.
@rinserepeat2877 mitsuba, I believe the link is for the updated version
Never Mind...I found it, 'Mitsuba' found on ebay too! thanks
Do Honda dealerships parts department sell relays and fuses ???
Yes , they sell. You will have to tell them for which engine part you need relay for as these relays have different Amperages and prongs .
I got a 2011 TSX with no a/c. A/c compressor isn’t coming on and the condenser fan isn’t coming on. I bypassed and jumped the a/c relay and the compressor came on but when I swapped it with another same sized relay it turned back off. What do you think it can be
If the fans aren't coming on either you may be low on freon. I would get the freon level checked first and see if its low and if it is check for leaks
@@FixItPhillip I fixed the leaking valve and got the a/c system recharged by a professional. But a/c compressor or condenser fan don’t come on. The compressor only turns on if you bypass the relay

Pretty sad that after only 125,000 miles. My ‘96 Camry wagon with 270,000, A/C is still ice cold.
Top of the relay comes off
They arc and build up arc corrosion that don't conduct electricity
My first move is swapping all the relays if they are all the same
