Hello my Honda family
So here i am to pester you all for my accord's issues.
MY AC doesnt work, when i try to turn on the AC button ( with blower speed on) , the AC condenser cooling fan dont turn on and neither do i hear the condenser kicking on.
I started with the most basic test of the fan by hot wiring the fan with battery and it did not work , so i replaced the fan with a new one and it still does not turn on.

second thing was to look at the fuse and that was okay....

my third test is to short the relay and see if condenser fan and the condenser kicks on.....

am i headed in the right direction?

all advice & help is very very appreciated.

GOD BLESS

 

ok sorry i cannot find the AC CONDENSER FAN RELAY under the hood fuse box....i dont think the 95 accord has one at all.
is it somewhere else??
im so now lost....

 

The condenser fan relay is located right beside the radiator on this generation Accord.

also I really recommend you get a FSM (Factory Service Manual) as it will answer a lot of the questions you ask.

 

thank you so much my friend. this clarifies

i can short both clutch relay and condenser fan relay to test the fan and condenser ? am i right??

 

The clutch relay triggers the clutch on the A/C compressor itself and has nothing to do with fans. The relay for the other radiator fan is in the fuse box as illustrated in the photo I attached.

 

so what do i need to short for the ac condenser fan ? the condenser fan relay right?

 

which wires do i short in the condenser fan relay plz? thank you friend

 

can anyone help me plz??

 

You need to jump the wires going to the copper pins on the relay(s).

I'm having the same issue as you. My ac clutch and condenser fan never come on no matter what I do. But they both turn on when the relays are manually jumped at the copper pins. So I know they work.

If you can jump both the compressor and condenser fan, then check the pressure of the low side freon port with a gauge. It should be between 25-30psi while the ac is running. If it's lower than that then you need to charge it up. By the way, if you do jump the ac compressor, you don't want to leave it on for more than around 30 seconds. You could destroy it if you leave it on too long continuously.

My freon levels are good too, so I'm still stumped. But I did a self diagnostic test on my climate control panel and its saying my evaporator temperature sensor is defective. So I'm going to try testing/replacing that next. There's so many components and checks that the car does to engage the AC. It's frustrating.

 

yeah but which copper wires do i short to make clutch and fan come on?
i dont know yet if my ac compressor is OK or not...so i want to jump it and see if that is okay.
if that work then that would mean the relays are out of whack

 

okay okay i get it, disconnected the relay connectors and looked inside and i saw the copper colored pins.

i shorted ac condender/clutch relay and i heard it click,
i shorted ac condender fan relay and the fan came on running full speed.

so does that tell me both the relays are bad and i should change them?
or should i test something else to find the issue??

all help and advice is very much appreciated
sincerely

Well that's a good sign. You heard a click, but did you visually inspect and look down to see that the ac compressor was spinning? You have to make sure it actually runs.

If those are all good, then you need to test the relays themselves. Or buy a replacement relay and see if it fixes either.

If both relays are good, and both your ac compressor and condenser fan are good, then you need to check the freon pressure level on your low side port while both are running.

You may be low on freon. Like I said, your pressure has to be 25-30psi or more on the low port (labeled 'L' on the cover) and no higher than 50psi, or your ac and fan won't come on. It's a built in protection feature of the air conditioning system.

If all those are good and your freon pressure is good, then you're where I'm at. I'm not sure about the climate controls with analog controls in your generation accords, but on my 1st gen CL (sister car), I turn the ignition to the ON position, then
press and hold the AUTO/OFF buttons. Which will display fault codes on the digital display if there's something wrong with the cooling/AC system. It's a self diagnostic feature.

The fifth gen accords may have one too, if you do some research. That should help you further.

 

oh no no wait i heard the click but it did not spin. i can check again but im 100% sure it did not spin.

and also my friend check the freon level and i he said it doesnt have any freon.

and if it did not spin you are saying its because there is no freon and i need to fill up the lower side?

did i understand that correctly?

and are we still considering both the relays as culprits?

 

and i think it did not spin because engine was not running.

 

No. The ac compressor should spin if you jump the relay. The freon levels won't matter. The freon levels just have to be right if the ac is working properly on its own.

You should be testing the ac with your engine on, not off.

If the Ac compressor doesn't spin when you jump the relay with your engine on, then your ac compressor most likely needs replacing.

You can further test this by finding the single 12 volt wire lead coming out of your compressor and hooking it up directly to your battery, with a seperate wire to ground.
