Original replacement part
Just want to say this is the original part. It works great in my Honda Accord 2008. Air conditioner was not working due to an electric fault, after reviewing in the web, first step was to check the AC Compressor Relay. This was our case. The part has been replaced and now the air conditioner is working espectacular. !!!!!!!

They all recommended to replace this little piece (relay)
I am a female and I don't know anything about cars. I have 2007 Honda Civic Sedan. My A/C stopped working about 1 year ago. I took my car to a few auto shops and those fakers told me I need to replace the whole compressor and it's $1,200! This summer (2017) I did Google research and found a few genius videos on YouTube how to fix Honda Civic A/Cs for 6 bucks. They all recommended to replace this little piece (relay). It costs $6 if you go directly to a Honda Location but here on Amazon is $16 (plus $3 shipping) - fine with me! So I bought this Power Relay on June 2017 (was fast shipping, thank you, guys) and replaced it! It worked!!!!! My A/C is working now! I am BEYOND happy! P.S. To make my car's A/C work faster and colder, I went to a local Valvoline Oil Change and changed the A/C filter (it really helped) I am all set!

A/C Works
After spending hundreds of dollars at the 2 Honda dealerships and a mechanics shop, it boiled down to a fuse. My A/C would work and then blow warm, til finally it would only blow warm. I would take it to the dealership and they claim they checked it out but was not able to determine what was wrong. It costs to have them do this. After the second dealership and mechanic shop visits with no success, I went to "Youtube University" and the Honda community said they had the same problem and it was a fuse. After looking at the fuse box and determining the fuse that needed to be replaced, I ordered 2. My son replaced the fuse for me and it's been blowing cold very season since. I am incensed with the dealerships.

Instant Air conditioner fix for my Honda Odyssey
I'm a 61 year old woman who recently bought a used 2008 Honda Odyssey. The air conditioner was lukewarm most of the time and occasionally cold. After doing online research I learned that Hondas are known to have faulty relays so I replaced my old relays with these. Poof. Instant ice cold air conditioning! There are videos on youtube that show you how to do this. It takes five minutes and a pair of pliers. This was an inexpensive way to determine if the relays were the problem. Even my mechanic, the most honest man I've met, would have charged me much more. And, if this wasn't the problem, I eliminated one problem for him.

~ $25 Honda OEM relay. Made in Viet Nam
Honda OEM ~ $25 part and a little expensive. So far so good. Don't know about long term reliability. Made in Viet Nam. Compare to an $8 relay generic brand at Auto Zone.

A little skeptical
I installed this today and so far my A/C is producing cool air. What I'm unsure of is whether or not this is a genuine Honda part. It says Matsuba brand instead of OMRON like the relay that was originally installed. The pic on the left is the new and pic on the right is the original I replaced. Just curious why the part that was sent was Matsuba. Did they switch manufacturers??

These are the relays you need!
Honda USED to use the Omron relays from the factory and we tried to replace our popped relays with those in the past. The Omron relays caused hundreds of dollars in damaged and broken parts. We learned that Honda no longer uses the Omron relays and switched to these Mistuba relays. I know it's cliché but seriously, get these. It's worth the extra you'll spend on these over the hundreds you'll have to spend in the weeks after using Omron relays. We lost our entire Honda Element cooling system due to the Omron relays. Spend a little more on these please. Learn from my mistake.
