[@ralphelishaw2961]

Man this guy on the video is extremely knowledgeable on honda a/c system. I changed my compressor, charged the system, still no a/c. I hot wired the clutch, a/c turned on. Turned out my particular problem was aftermarket (-)(+)negative/positive, terminals on clutch. They were not crimped tight enough from seller. So I used information from this video along with new heat shrink crimp along with disconnecting thermal switch from compressor (you can leave it hanging long as it is zip tied)+ 3 Zipp ties so wires are secure no dangling. Problem solved and I feel like a million dollars. Thank u for this video. Hands of God...

[@user-xl7yv8iy7j]

Im not a mechanic but a diy’er. I know enough to be dangerous. Took my Honda to 2 shops. First one put an electronic tool on the compressor for 15 seconds and said it was the compressor. Promptly left cause I knew it wasn’t. Second one wanted to flush and recharge. Knew that wouldn’t work either. Figured it was electrical. Watched this gent and replaced the relay and Walah. Cold air!!! I subscribed my friend. Thank you!!!

This is a great car i drive it myself, the ONly fault with the 2007 Honda Crv models is the a/c is not designed well, i think everyone commonly has this issue with this car

[@jamesbondaygee]

That's what I'm hearing. I got my used, it's got a lot of kilometres but drives amazingly well

[@maverickmacgyver]

The modified ice trick is to use those aerosol duster cans (upside down) to spray liquid cold love onto the sensor.

[@E85_STI]

I was just about to say that but that’s a great idea.

Thank you. I’ve spent 1500 bucks to get this issue fixed on my 2007 CRV with 165000 miles and it still blows warm air for about 10 to 15 minutes before the compressor finally comes on , cooling the air. The compressor has been replaced and one other part. Thanks, this is very helpful!!

Thank you so much! I have been tearing my hair out over my AC. The shop always wants me to bring it in during the morning, when it's not hot enough outside for it to fail.

[@sistercalhoun4444]

Can you make a video on how to replace the thermal switch ?

[@ronald3100]

FYI - MY Ac would stop working when the car engine warmed up on hot days. Worked fine on highways though. Clutch would not engage after car was warmed up. There was plenty of Freon, Condenser didn't seem clogged but issue was AC coils when they got hot would disengage the clutch. When cooled back down would rengage. I bypassed the thermal protector and that also did not work. Very common issue on Honda CRVs.

[@Victor-bb4cw]

That’s the issue with my 2008 crv. We’re you able to repair it? If so, how? Thanks

Y’all know how to check if your Low pressure line still has pressure? Just take off the cap on the low pressure and press the pin with a Philip screw for like a quick second. If there’s pressure you’ll here it releasing some, so if it’s not than you’ll know it’s either a sensor or a bad clutch. Some would say it’s a leak but the reason I say it’s not a leak is because even with a leak you can still add more freon. One time I inspected someone’s new used 2007 crv and the ass hole who sold it to them, didn’t even have the serpentine belt wrapped around the ac compressor..... so yea look out for that too.

At the 3:10 minute mark, what exactly does your probe do to that terminal to engage the compressor? How can I do that test with a jumper wire? Jump to Neg. battery terminal or the Pos. battery terminal??

[@andrewgomez9632]

When you change the pressure switch do you need to empty the AC or is it just a heat sensor

[@brianiswrong]

It's just an " external" switch, by that I mean you don't discharge the AC gass to change it.

[@colinyeates8185]

If you are sill reading this would you suggest possible problems when the compressor is turning on but no cool air. One pipe is very hot, the other is mild at best not hot still no cool. I had o use about half a can of gas and it kicked on No Problem but no cool. The instructions in one can says to fill until cold air comes out but on the can I bought it says not to overfill and it has a gauge but the gauged seemed to act weird. but after several rounds it settled out in the right area.. still no cool compressor stays on no problem and when you turn off the cooling it turns off no problem. I am thinking since it sat Unused for so long without proper levels that the radiator inside with the release of the compressed gas, is clogged so that none is getting released so no cooling. Your ideas?? much appreciated

[@kellybrettingham7133]

Hi, i have tried this but the clutch didn't engage - could this be because i have no gas in it or should it still engage even if there is no gas in (had the gas taken out when i replaced the pressure sensor) - when plugging it into the honda software it comes up saying Thermal pressure switch on
