Alright its getting really hot here in Florida and my AC isn't cooling me down at all. Anything higher than 2 won't blow any cold are out, its almost warm. Not to mention the fans turning off every 15 seconds so I get a blast of warm air in my face for about 5 seconds. Is this normal for such a small engine? I really don't want to take it in to the dealer.

 

Dealership time...there is another thread around here about it cycling on and off frequently. Thankfully mine doesn't have that trait...takes a while to cool down but it eventually does. With yours not blowing cold above 2 I'd say you definitely have a warrantied issue.

 

I may have a similar issue. I was driving around noon in ~86F temp. Today was the 1st time I had my AC run for a lengthy period. The AC was blowing only slightly cool air above 2 (was @ 4 to be exact). I didn't think much about it since I dropped it to 1 after a couple of mins. I have to further investigate. I also noticed that the blown air smelled like coolant at times.

 

High of 94 getting hot? We've had 100+ here in Texas since before the beginning of summer and my AC runs cold and I run it ALL the time without any issues! Take it to the dealer before it gets worse and you have to be without your car for a longer period of time.

 

There are different types of hot. Florida is hot at 94, with humidity around 90%. Texas (in places) is hot at 105 with 30% humidity. I think high humidity heat is harder on the Fit's A/C than low humidity heat.

 

As measured by my weather station at my house (the sensor has a radiation shield and is positioned far from the house, in clean air), yesterday's high temperature was 116.8 deg. F here in Phoenix. In conditions like this, the Fit's A/C is essentially useless, unless you're on the highway, cruising at constant speed, it's in recirc mode, and it's had a good 20-30 minutes to cool down. Stopping at a light for even 1 minute will bring the vent temps back up by 20-30 degrees. I measured vent temperatures the other day (it was only 115.5 degrees) after driving in urban traffic for 30 minutes as high as 85 degrees. Our Sienna's A/C is also pushed to the limit, though it works better. My Boxster's A/C blows cold in under 2 minutes and stays cold in the same conditions.

 

tokyo/osaka hot is 98F with 99% humidity. we'd think these japanese folks would learn how to make a more powerful a/c by now.

 

Lol...you would think

 

You may have an issue - not sure. It was 115 degrees here yesterday, but after a couple of minutes, my AC is fine.

I usually put it on interior air, roll down the windows and start driving. After 30-60 seconds, roll up the windows and press on.

Seems like it takes a minute or so for it start blowing cold air, and it does cycle a bit, but like I said - after a minute or two it seems to work great.

My boss has one of those solar powered exhaust fan things that mount on the window while you are parked - he says it works pretty well. Can't vouch for it, but something to consider, I guess.

 

Have you tried having the A/C system cleaned? The way I see it, the refrigerant (R134a) isn't circulating as well as it should because the lines are clogged, creating a high-pressure situation. In the long run, that'll tax your A/C compressor and lead to idling problems. It happened to me last year.

General A/C cleaning is a must here to keep the cooling humming along.

By the way, Manila heat is 34-38 degC at 89%+ humidity. So yeah, it's sticky sweltering heat we get here too, not the dry piercing kind that US desert areas get.

 

qbmurderer13 here in Dallas we've had a series of 100+ degree days, but the humidity thankfully has been below 50%. However, the end of July and all of August is typically the hottest with high humidity.

I work at 6 am so I run the A/C in open circulation mode, but when I get off at 3 I run it in closed circulation with no problems so far. I usually close my far passenger vent and that helps as well. I will keep you posted when August roles around if anything changes.

 

After having my FIT in for A/C service 3X the dealer finally agreed that the A/C was blowing warm air and found that the A/C switch was faulty. While the green LED was LIT I think the compressor was not always on. Bottom line it blows ice cold... so far and I live in the desert in AZ.

 

Funny, my AC switch IS having problems. If I hit a hard bump it turns off and if I just lightly tap it it switches off. Lately its been working fine though. Ill take in anyways.

 

Wow that IS odd. Really sensitive switch you got there bro...
I've hit quite a number of hard bumps and ruts and my A/C switch doesn't budge.

 

I got my switch replaced two weeks ago, same problem. The dealer resisted ordering a switch even after I demonstrated the problem for the service manager. Upon my insistence, dealer called Honda "techline", who instructed the dealer to replace the switch. They said mine made the fourth documented a/c switch failure. I'm sure the number is much higher.

The new switch seems to stay lit even with me tapping on it. Hopefully, it will keep working properly.

 

If you're in Scottsdale and you're A/C is working well, then I guess there's hope for mine. The cycling on mine is the problem, if they can fix that, that's great. Thanks!
