Honda Civic 2009 FD Intermittent Cooling

[suysuy]

I have a problem. Yung aircon ng honda civic ko intermittent.

Minsan pag parked under the sun, 5mins bago lumamig. Nag on ang fan ng radiator pero walang click sa compressor. Meaning parang fan mode siya.

Minsan naman pag malamig na, natural nag ooff ang compressor pag yung desired temp or lamig ay naabot na, pag once need ulit ng compressor umandar, hindi na siya ulit umaandar. Kaya wala nanamang lamig.

Turning off and on the aircon repeatedly can sometimes fix the problem. The compressor engages. But soon after a while, when it disengages, it wont engage again when the need arises.

I've read baka ac field coil daw yung may problema. Heard of this problem? Is there an easy fix for this? And how much?

Pabawasan mo ng spacer yun magnetic bigyan mo lang tip yun gagawa
no need to evacuate freon dukutin lang yan or Check mo yun relay ng compressor

I experience this from a friend's Optra. The operation is intermittent just as you described. The same solution is just as what you've said, repeatedly turning off and on the switch until it runs.

One possibility is the ECU, somewhere around it that sends or controls the signal. We haven't verified it as the owner didn't want to spend a few thousand pesos for the diagnosis and repair.

The solution? Connect the wire directly to the battery. As soon as the car starts, the AC will run. Certainly not the best solution, but it worked!

Hindd ganyan ka grabe yan sakit talaga ng FD yan intermittent A/C either relay lang or bawasan yun spacer

That happened to my fd as well. The mechanic adjusted something in the compressor, spacer nga ba yun? That solved the problem. I gave him 200.

Thanks for the tip. Mura lang pala kung ganun. Kung bibili nalang ako ng bagong magnetic clutch mas mabuti ba? No need pabawas ng spacer thingy?

Perhaps it will be much easier to "fix" it, if that spacer thing is really an existing issue.

The decision is yours. But the fix is relatively harmless and so much cheaper than the alternative.

that spacer/washer can be removed for next to nothing. with a little practice, you can do it yourself. and the fix should last several years.
if i were me, i'd consider buying a new clutch, only if there is no more spacer to remove. "sagad na, 'ika nga."
also, mas mahirap palitan yung buong assembly, kaysa sungkitin lang yung isang washer.
magkano ba magnetic clutch ...? 3K ba...? nalimutan ko na...

Every post herein is pointing straight to the compressor clutch indiscriminately without checking the high and low side pressures. If you were mechanics, you will have misdagnoses left and right. Learn the scientific and logical approach. Dont be just parts replacers, be or try to be technicians

True, but advices given was based on experience and besides the issue is well documented and a known problem of the said model.

And considering these advices saves time and money. If an advice didn't work, then you can always go to other routes.

That is, hopefully you get lucky that the guess is right.


You dont take suggestion of an open heart surgery on guesses, you consult, get other logical explanation and diagnoses. If the chest pain was caused by hyperacidity and you learned after the surgery, oh well

Extreme ba yung suggestion that you would compare it to a surgery? Diba aadjust lang yung spacer?

medyo extreme nga yung choice of surgery. let's tone it down.
maybe, excision versus FNAB?
heh heh.

This might be the problem of my friend's Optra, a faulty pressure switch. However, I remember that the technician said that the pressures are normal BUT did not check the condition of the pressure switches.

Anyways, the pressure is usually the first thing that a technician will check first once you bring it to a shop. From there, he will start the troubleshooting process.

yup.
that's what they did to mine. sa katapusan, it was just, as initially suspected, the spacer.
these guys are pretty good "at guessing".
i guess, that comes from seeing dozens of similar cases a month.

First two things to look out for, in order:
1. AC compressor relay located at the engine bay fuse box - easy diagnosis is to listen for a mild click from the relay when you turn the aircon on, if there is no click sound then this part is bad
2. Magnetic clutch spacer (washer) - if there is a click as per #1 but the AC magnetic clutch does not turn/engage, then this is likely the problem

It's possible that something else could be wrong but the above are known issues with easy fixes and a mechanic familiar with the FD will first check for those anyway. We are here to point you in the right direction so that you have an idea what to expect based on your indicated symptoms since the casa and most AC shops will insist that you immediately replace entire assemblies, that are otherwise still working fine, given the age of your car.

When my FD had the spacer removed at around the 4-year mark, the casa wanted to replace the entire compressor assembly (~P23k) while Frigid Zone wanted to replace the magnetic clutch assembly (~P5k including pulldown and Freon refilling). TeamFD folks back then suggested I look at the relay and washer first. It turns out it was just the washer and it was a 1-hour/P250 job. 5 years later, the relay failed. At that point, I replaced both the magnetic clutch (P2.5k) and relay (P150 surplus) since the clutch was also likely worn out. When the compressor was opened and inspected, the technician asked if I had just replaced the compressor and I said it was still the original factory part. He said it was remarkable since the oil was clean and the insides were in near perfect condition as the pistons and cylinders were still shiny, clean and tight. This is from a 9-year old AC compressor used in a daily driver that had around 100K kms.

The two suggestions given was the cheapest and easiest things to check and it have done. If both are the not problems and magnetic clutch need replacement then there's no harm done in the compressor or his wallet.

I still follow the sequence of
Knowledge
Diagnosis
Repair
In that particular sequence.
I avoid making mistakes that way.

This have been outlined by John Remling in his earlier textbooks that I used in my classes for more than two decades.
