Honda Pilot AC stop working - How to troubleshoot HVAC compressor relay G8HL-H71 - Air condition

[@migdaliamedina2143]

Thanks to your video, I cancel my appointment with the dealer who was going to charge me $1000 for repair. I quickly check the relay and sure enough, it had a raddle noise just like you mentioned. Instead of taking my Honda Ridgeline to the dealer for the expensive repair, I went and picked up a new relay for $26 bucks. Thanks again! John

[@harrymccron1777]

A great many you tube presenters should watch this video to learn how to create an excellent instructional video!! It is well presented (video, audio), concise, and not too long or too short. Well done !!

[@jkmochamaster]

Fixed my 2007 Ridgeline with this information. The local Autonation Honda dealer wanted $180 just to diagnose the AC problem. Thanks so much for the great video! $6.99 at Discount Auto Parts and I have cold AC.

[@duanedonaldson2262]

Thanks so much for the diagnosis and tutoring, it would have been nice to see a test of the new relay to show folks that the resistance on the contacts would instantly drop to ZERO ohms when you power up the control side, this is an issue on youtube is not many people will show what a good part tests like. Also for testing purposes, there is probably another same part relay in there somewhere that can be temporarily moved over to this position to prove a bad relay if the clutch operates by swapping relays. Thanks again.

[@daveexel77]

Amazing! Condenser not engaged, no signs of visual leakage, nothing shaking around in the relay, swapped out the fan relay with the AC relay, and Bingo, Condenser engages when AC turned out, cold as ICE! $6.69 for a new relay! THANKS!

[@henrytan5707]

My 2007 crv suddenly had no cold air, I tried turning a/c on and off several times , the cold air came back out, I guess it must be a relay problem. Thanks for the video, and your elucidation is systematic and educational.

[@henrytan5707]

I just changed my aircon relay, it turned out that it was exactly the relay that was broken, the rest is fine, it works perfectly now. Thanks so much, you saved me so much money!

[@garyfriedlander2396]

Thank you for posting this! While my relay did not rattle, it did test bad. By substituting another G8HL-H71, I confirmed my finding. Time to go purchase a couple of these relays! You saved me a lot of time and a trip to the Honda service center.

[@migdaliamedina2143]

I forgot to mention that the relay was the problem and the AC works great!. Wow! Thank you again. John

[@jamesmcconnachie7748]

You are a bloody genius. Thanks so much. It worked on my 2010 pilot.

[@robertpaturzo487]

Thanks for the information, worked for me. Cost me $8.99.

[@colintaylor4588]

Very well presented - thank you! As an engineer, I appreciate the primer on the a/c system before diving in with the video. Clear, calm and educating dialog throughout. Now I have three thins to check before taking my Pilot to the shop… blockage on grill, leaks and relay. 10/10 for this brilliant video!

[@PrimalWoods]

Great video. At the end however the endscreen links to other content covers up the view of the AC compressor.

[@stevemariegreenwood9771]

Thanks for your time in this video I now have cold AC

[@joedonahue7352]

What what is the AC in the fuse box

[@TrevorTurkington]

I got my relays from a wrecking yard today and fixed my Honda Civic. don't worry about the serial number on the relay just make sure its the same voltage and ohm rating. I searched many cars and then realized they have different numbers on the relay. Also the fuse panel on this Pilot looks identical to the one on my civic so civic relays should work but I may be wrong.

[@rohornback]

Thank you this was very helpful. Interestingly my did not have any broken parts inside (did not make noise when shook) and when I put 12 volts 1 amp to it, the solenoid closed (I could hear it click). But the circuit did not close as checked by the multi-meter. So it was still bad. BTW I bought a new one at O'Reilly Auto Parts $7.99.

[@commonman80]

You did AN FANTASTIC JOB On this Video... Learned A Lot... You're A Natural... Thanks...

[@jamescc2010]

You are very knowledgeable. Thanks for the great vid.

[@TheSargeOnTheWater]

So what if the clutch stays on or spins even when the ac in car is turned off? I heard 2 bursts of air and so i opened the hood and could find it and later did some research and my conclusions is that sound is the release valve as it runs even if the ac is turned off

[@brianpowell8829]

Many thanks my man! This worked for me.

[@iculamar]

Wonderful video! Thank you so much for posting this informational video!!!

[@rn8179]

Well explained debugging AC issue. Keep it up

[@arieldecastro8750]

Hi,i have a 2017 pilot.i have a problem with my ac its not blowing up cold air.

[@MrAletube]

i had same problem on my 08 Civic,found a couple of relays on ebay,done.

[@Yankee2be2010]

Great video. What would the problem be on my 2006 Ridgeline if no air is blowing? i hear it trying to turn on but doesn't. Clutch relay was bad an i replaced.. any other ideas?

[@Cougarfan01]

Super great instructions. Thanks.

[@MMMota-sl4ju]

Hey, I have a question about your video, I have the same problem with my car, all the lights on the board are on but the air conditioning does not work that you think I can do.

[@mushreqalrubaye9605]

Many thanks, very informative

[@MrAdoons]

Best video , thanks alot for all offers

[@telecasterbear]

my 2008 civic has the same fuse panel under the hood. is one of the relay there for the horn? horn not working, fuse is ok.

[@cocojambo28]

AC clutch is not engaging and AC Condenser Fan is not turning at all when I switch AC on in my Civic. I tested the AC clutch relay replacing the Horn relay with AC clutch relay abecause they are of the same type, and the Horn worked well, also on the other side the AC clutch didn't turn on. What could be the problem? I have not noticed any AC oil leak and I can't test the AC pressure because I dond't have a multimeter, but I think everything should be fine because in Autumn everything worked fine and when Ive tried ti use my AC in spring it just didnt turn on. What would you recommend me? I've read that the other problem could be the termal overload protector that won't let the ac and fan to turn on. Does it also make sense to test the AC fan relay? Thank you very much for your nice video! It was very informative, detailed and practical!

[@timmeadows7644]

Check the condenser fan relay

[@cocojambo28]

Tim Meadows, I've allready checked. It still doesn't work.

[@timmeadows7644]

I just replaced the condenser fan on A Honda Element because when I turned it just a little bit it would blow the fuse, But that was while the A/c was on. I guess the fan had a short in it. Un plug the condenser fan and try to see if it works.

[@cocojambo28]

Tim Meadows, could you help me with the location of the plug and how to access it? I am not sure if it is it. I have a Honda civic hatchback 2.0i sport 2004. I can see a plug that is comming from the condenser fan, located on the passenger side of the car, under the metallic border that is hard to access with the hand. I should take something out, but I'm not really sure where to start in order not to destroy the car :))

[@timmeadows7644]

That is the plug all right! Please take a picture of that metallic shroud thing and Email me [e-mail]

[@alizamanian7183]

My 2007 Honda Civic ac air is running at 56F+/- 3. The compressor pressures are 175 and 35 psi. Refrigerant is good. Any ideas? Looking for 35-40F.

[@dabeev08]

Where did you get the hvac manual?

[@timmeadows7644]

This 06 Honda Element is giving me a hard time. The condenser fan fuse keeps blowing out! I spent hours looking for a loose ground or frayed wires and I still can't find out why it's blowing fuses.

[@timmeadows7644]

The condenser fan had a short in it. I just unplugged it and it worked perfectly. The fuse blew when I tried to spin the condenser fan. I replaced it and it works great now.

[@thewolfhunter]

I have a 04 Honda Accord and I replaced the relays and the system is charged but warm air still comes out.... What gives.?

[@ajzarnel]

Is it safe to short the normally open contact on the relay box to see if the clutch or compressor is working?

[@DIYTinker]

Zarnel Mejia not really. the pressure switch tells the computer if you have correct Freon level. If you dont, then the relay doesnt close to protect your compressor. If you dont have correct freon level, then running the compressor will damage it.

[@neoplasma1]

mine is making this grinding sound and no cold air at all...any ideas?

[@MikeKokoschka]

Clutch ball bearing ....must likely.

[@courtneydawson3956]

We replaced relay and now have cold air but it hardly blows on our 2007 Ridgeline.

[@GoatRoper911]

+Courtney Dawson Check your in cab air filter in the passenger foot well area.

[@bobbydhal2199]

Awesome video

[@joeymalino9440]

what if it smokes and smell of freon???what do you think it could be

[@DIYTinker]

Maybe a freon leak? blown compressor? not good for sure. :)

[@rovespierr]

thanks for the video

[@leonardocardoso1594]

Hello my name is leonardo . and I'm using google translator . I live in Brazil. First congratulations for the video. I have a Honda Civic 2007-07 automatic LXS . he was a few days without battery. there bought a new car and put it on . over there 02 relay the fuse box fire. everything works in the car. however turns on the light injection departure over the car does not turn on. already checked several grounding points more nothing changes. I would like your help . What can it be ? these paltry and what part of the car? pass me your email I will send the photo . the relays . the relay that triggers and this black next to the orange relay required

[@axxiom20001]

Thank you for posting this! My 2009 Pilot AC stopped working. The refrigerant cooling level was OK, so I watched your video and found the compressor was working. Next I checked the relay. Took it out, put it back in and Voila! the AC started working! Can anyone explain why simply removing the relay and plugging it back in would fix the problem?

[@abrahamigunma]

Maybe it lost connection or some dirt came in between the contact and relay.

[@monter_dan]

I have a 2011 pilot but im only getting cold air on my feet and there is no air from the center ventas, could that be relay related?

[@youtubebitchcenter1463]

Daniel MP Probably your blender doors are stuck and not opening, maybe?

[@mikepoz3783]

Thank you for this video! I am on a road trip and my AC died. I found a Honda dealership, bought a relay for $20 and was back on the road in under 10 minutes. Works like a champ. Thanks again, you saved me a lot of money :)

[@christophevergelin851]

Je te le dit en français. Merci beaucoup grâce à ta vidéo j’ai réussi à réparer ma clim de mon pilot. 👍

[@xelasmada16]

This is a great video. However, if you don't have a meter, try this: On my 2005 Odyssey, there are 3 of these relays. One for the A/C clutch, and two for the fan speeds. An easier way to confirm the relay is good or bad is to swap one of the other two for the A/C clutch. If it works, you have a bad relay. Just go to a local auto parts store and for $7 or more, get a new one.

[@robsanchez5742]

I found out...Advance Auto Parts "Carquest" part RAA1731 is the same as Omron G8HL - H71

[@ginam5603]

I also have a 2009 Honda Pilot. The AC went out about a month ago. I decided not to replace it just yet. Then, last week my car did not start. I went to have the battery checked and it was deemed good (it's a year old). Just a year ago, I went through the same issue and my Honda dealership replaced a relay. Voila, all was back to normal. Remembering this I took it back to my honda dealership to see if they could trouble shoot and see if it was the same relay that needed replacing. They just told me that it is the AC assembly that needs to be replaced because replacing the relay alone will not fix the problem and it (the ac relay) will continue to drain the battery. I've never heard of such a thing, that basically if the AC does not work, the car will not work. Your thoughts or feedback would be greatly appreciated if you have a moment. Thanks so much.

[@beaubo67]

Fantastic video, thank you for sharing

[@btnled357]

Wow. Ive just brought a Honda CRV 2008. Knew the ac wasnt working but ive been fiddling around with it. I already found the relay was rattling and have ordered a couple of replacements off ebay before I saw your vid but they havent come yet. Big coincidence finding your vid and you having a rattling relay too. Ive already tested for pressure in the system with a gauge and it seems fine. Not found where the pressure switch is yet...Was the relay REALLY all that was the matter with your system.? Cant wait for my replacement relays to come to see if it works cos a compressor change is just too expensive on a 10 year old car.

[@geojor]

thank you for this...

[@chemicalabstract]

hi! thank you for sharing. The AC of my Honda Civic 2006 does not work, normal ventilation is fine. Symptoms includ: AC condensor fan not working and AC compressor not working. I just tested my clutch relay and it is good. Any suggestions? thanks a lot

[@danielbautista4686]

Hello im looking for some help i have a 2014 civic im having problems with AC not disengaging and. Stays on atvall time hope to hear from you soon

[@andygenner5360]

I've changed my relay still nothing. Unplugged the pressure sensor and reconnected it and it worked. But now it's stopped again. I think I've got a bad wire to the pressure sensor.

[@gerritkolthof2773]

Thanks for the usefull video

[@benjy92500]

Great video! I had the same situation with my 2009 Honda Pilot and changing the part saved me the $45 diagnosis, etc Thank you very much!

[@gregnixon1296]

This worked for me on my 2009 Pilot. Fuse/relay was $8 at an auto parts store. Took less than one minute to swap the new one for the old one. Thanks for the help.

[@eli25jk70]

If only mine was the relay problem. I have to replace the coil on my Acura TL

[@kevinarmstrong864]

What web site did you get the honda info from been looking for wireing diagram s any info appreciated thanks

[@bigfoottoo2841]

What about the expansion valve? You never mention it.

this saved me an easily 300$ ... thanks a bunch

[@gumby9220]

You just saved me $1,600.00 Thanks

[@tkajohn]

Great video, thank you. Did you buy the new relay from Honda or did you find an aftermarket brand?

[@DIYTinker]

Thomas Kajohn Got it from Honda. But aftermarket brands are almost 1/2 the price.

[@bigfoottoo2841]

Cut the cover of the relay off with a Drexel

[@emilfalck5470]

You are a good teacher, thank you for showing us ,

[@danielesquivel7569]

I have the same problem with my Tl

[@dubyajayyo]

Can a relay fail intermittently? Or do they just die altogether?

[@kalani1987]

I have a intermittent problem on my AC as well. I will try and change out the relay. How did your issue turn out..was it a bad relay?

[@victorneyra1206]

original relay (omron) for $5.99 at autozone

[@DIYTinker]

Victor Neyra really? can you post the part number from autozone? Really appreciate the info.
