Honda A/C Not Working. Air Conditioning Not Blowing Cold Common Problem

Air Conditioning not blowing cold on this 2007 Honda Element. In this video you'll see some common problems which can be found with Honda Acura, (besides having a freon leak of course, failed compressor ect...). Just a couple common problem areas to check that I've found over the years if you have a no ac problem.

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 .

That was awesome how you diagnosed everything. Makes me look at things different.

[vinhthuantran]

I learned many new things from the video. Thanks for your thorough explanation and demonstration. It was straightforward and educational.

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!

Great video. You do a good job at explaining things. Thank you.

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.

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.

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?

[pamelabogacz]

Do you have a tutorial on how to Santech A/C Switch MT1618 on a 2010 Honda accord cross tour?

[luxmagnumofficial]

Couldn't you have figured out if relay was bad by just swapping it with a known good relay? Like h0rn relay?

[oldbiker]

Thanks Ill have to check this on my 22 CRV .

[patrickjohnson]

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

[SnKCOL]

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.

[turbineking]

Great information, so the Amazon link is the Matsuro relay? What fans are good? Also what fan swich is good?

[ryanmarch]

2008 Honda Odyssey HVAC Blower Motor Resistor, Front by Airtex was my problems after all the relays

[rinserepeat]

Hi was wondering what the 'upgraded relay' number was or what you were calling it? Video was blury for that image.

[ledertoug]

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!

[jbl]

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 ?
