Hey guys, I need some assistance.

I apologize in advance if this topic came up before, I don't have the opportunity to search the threads.

So if this did come up, if someone could point me in the right direction, it would be much appreciated.

As of Saturday, my AC has been blowing warm air. Prior to that day it worked perfectly, but now it's just hot air.

My ride is a 06 V6 sedan with Navi & climate Control.

Would you guys know if this is a busted AC unit or if it is as simple as needing an AC recharge.

Since I no longer have a warranty, is there a way for me to diagnose this without taking it to the shop.

Thanks in advance,

Probably just need a recharge.

Did you make sure it's on 'cool'....kidding!


I dont know of a way to check it yourself. Usually, depeding on the shop, they'll check it for free.

are both sides blowing hot air or the passenger side is colder? that happen to me and all i need it was a charge and to replace the valve stem..

How many miles do you have on your car? My clutch went out at about 55k miles. First I checked to make sure the compressor was getting power. It was so I just took it in.  We have had a few cars with clutches going bad, so I would get that checked. I went out to eat with cold air went back to my car to go home and I had hot air, so it sounds similiar. In my opinion if you need a recharge already there is a problem, but then again what do I know. Good Luck.

Thanks for the input.

Both sides are blowing hot air.

the car just has less than 31,000 miles.

Bill, do you mean the compressor?

On my previous 03 K24 sedan, I had about 36,000 miles on her when I traded her in and the air was blowing cold. it's funny that once the warranty is up, now the fun starts. lol But these are hondas, so we shouldn't worry.

Probably just needs some refrigrant, get one of those recharge bottles that includes leak detection dye, when you get here I can look for any leaks....

i hope you get it fixed before your trip.. a 4000 mile trip in the summer.. no A/C.. ouch.

Worst case he gets to me and I'll get her fixed.......

I'm talking about the clutch on the compressor. My compressor was fine, the clutch was just "burned up" as my mechanic said.

^Yeah, that happens, but is very rare on these Denso compressors.

I went through a ton of work to fix my A/C issues a few years back.  Here's what I did.

- vacuumed and recharged my refrigerant (with IV dye to check for leaks)
- after we determined that there were no leaks, we tested the compressor clutch and found that it wasn't engaging
- replaced the compressor clutch
- replaced the condenser
- replaced the low pressure line because I broke it while replacing the condenser
- replaced the compressor

Replacing the compressor finally fixed it.  I hope that you don't have to go through everything I did.  I'm sure Paul will be able to get you taken care of though.

Thanks for the info guys, The weekend is coming and I'll test it out. Hopefully its something simple as a recharge.

Update: I just remembered that I have mechanical breakdown coverage through my insurance and I just had it confirmed. So, if it is something more than a recharge, I am covered  

What was wrong with it?

Don't know. I haven't taken her to the shop yet.

Any help on diagnosing this so I can try and get this resolved with as little $$ spent.

My ride is a 2006 V6 Sedan everything worked perfectly up until recently.

Less than 2 months ago my Air Conditionioning (AC) was blowing warm air when it was set to max cold. I had it recharged with the black light reflective dye, checked for leaks and no leaking.

Last week at a meet my AC was at first starting to blow warm air again and a few minutes later blew cold air at the passenger side and warm air at the drivers side.

Any suggestions? Recommendations? or Donations to help me get this fixed, lol

I would get an A/C Performance Check done by a shop. It seems like a possible schrader valve is leaking. Point the UV light at the high and low side valves, and see if that is leaking. You are losing freon, and a common leak is the schrader valve. Do not attempt to do this yourself. It is against federal law for anyone to expose freon in the atomsphere, and it should be handled by a trained and certified technician and shop.

I really can't add anything to this but I'd go with what Thien is saying. BTW, I merged both your HVAC topics Arie so as to not clutter.

Thanks Thien, this is one thing that I have no choice but to bring to a shop, but totally sucks to lose the $$ on this.



Thanks bro, I totally forgot that I posted this up before, damn memory doesn't work anymore.

Too much taquiela, LOL, but yeah time to get a shop involved unless you want to drive back down here....

so I noticed no one mention rattling coming from the compressor area when the A/C was on and only on. Anyway to make a quick fix without avoiding not using your a/c? I looked up the OEM compressor and it is quite expensive. The way I'm headed I'll never save enough to get the mods I want....  :'(

big FML

I had AC problems in the past and I ended up replacing my compressor with one from a wrecked 2006 Accord that I picked up for $75 from a local junk yard that I found through car-part.com.  It's worth your time to search locally for junk yard parts instead of paying full price for brand new OEM parts.  This is one of those parts that I would do that with. 

Thanks Tim, not sure if I4 and V6 use different compressors but I could not find one for that low. $100 is still better than $500!

Yeah, for the $100, it's worth it.  Just try to find one from a low mileage Accord.  Mine is still blowing cold air.

You are going to need a compressor. Your compressor clutch bearings are more and likely worn out. No way of fixing that but to replace the whole compressor.

I've replaced my compressor clutch before.  I know you can buy a replacement for the K24, not sure about the J30 though.

Wow, I forgot about this thread.

to let you guys know, my AC issue was a "catastrophic failure of the air conditioning system"

Luckily I have mechanical breakdown coverage with m y insurance and they were able to take care of the bill for me. Totoal billed was 2900 to replace my AC system and all I paid was a $250 deductible.

I'm literally CHILLING now  ;D

What exactly was the "catastrophic failure" you had?

From what the shop and Geico told me, the compressor failed but was still functioning and ended up grinding some metal within and pushing the metal bits & dust throughout the whole AC system. They replaced the whole system.

When I buy a new car I will def. have to get MBI. It really worked out for you!!!

I did not know there was such thing as MBI, I dont think my insurance (State Farm) has it though. It's def. better than an ext. warranty. I will consider it once I turn 25 in August!

Yup, Gecko is excellent. Not only did they save me a bunch of money when I switched (LMFAO), they have the Mechanical Breakdown Coverage. Only thing is that I believe it's only good if you have the car new.  But you can find that out easily by calling them or visiting their site.

Wow, they should pay me for this.

Geico really saved you money? Your previous insurance must have been stupid expensive.  Geico is one of the most expensive insurance carriers, so much so that my cousin that has been working for them for 20+ years doesn't carry their insurance because it is more expensive than the competition.

Yeah bro. I had several other carriers and at the end Geico was the cheapest. I even have a friend that works for Allstate and he can't come close. Plus I'm in NYC with several accidents under my belt. Fucking stupid NY drivers, ruin my record.

Maybe it's regional because GEICO was the cheapest by a mile for me to. I have a pretty clean record (one accident) they were about 350 cheaper than anyone else for a yr.

Shit, when I was shopping for cheaper insurance after moving to Miami, EVERYONE was quoting double what I pay now. It's most definitely regional.

Geico wouldn't even insure MA drivers until a few years ago. 

My Dad has travelers. It was pretty cheap compared to what we had. It covers our real estate too though so that might lower it.
