2007 honda accord 2.4L
So a bit of a story but the ac doesn't blow cold and the clucth won't engage I got everything to replace the compressor I checked the psi in the low and high
The low
125/350 in between
The high
125
I've already checked
I had got the compressor checked and it gets power but the clutch won't engage I was just gonna get a used one from a junkyard and switch it out but I'd like more of an input please
You need to do some electrical troubleshooting to determine why the clutch is not engaging. You can easily check the clutch itself by connecting it directly to +12V. Another possibility would be a faulty low-pressure cutout switch. That can easily be checked with a multimeter. The shop manual for that car may help in more in-depth troubleshooting.
If your compressor turns out to be bad another 17-year-old example from a junkyard is likely to be as bad or worse than what you already have.
I would like to point out that it didn't have the splash guards so I'd assume it got all wet and everything I would like an input on that aswell please
Not likely. The splash guards on my own car fell off in the road years ago and I've had no problems.

Depending on the ambient temperature, a properly running AC system is around 55 PSI on the low side and 250 on the high side. Idle, with the A/C off should be about equal after a few minutes. Did you seriously overcharge the refrigerant, or something? The clutch won't engage if the pressure is too high.
I didn't over charge it but if it was what could have happened cause I did drain out 125psi of freonband compression
I emptied all the 125psi of freon
Well, unless you used recovery equipment you have just admitted to a federal crime in a public forum.
I had a guy Check with a power probe it gets power but it will not engage
If the AC clutch is getting power but not engaging the clutch coil is bad.
So I've checked everything on the qc wethere it was fuzes,relays,n even sensore they kick everything that should be kicked on on
I bought this car off some guy didn't know why the ac didn't work so I got some gauges and it was on retard mode I emptied all the 125psi of freon I reset my car and tried it agian and I don't have anything from the clutch I had a guy Check with a power probe it gets power but it will not engage
Any help would be very appreciated as its getting hotter
I'm checking the compressor and the top part of the screws is like burnt up corroded and it was the part that goes all the way in the to hold the the ac line in it

Okay so sir I've checked the fuses relays sensors the car registers I there's too little freon and will not engage the fan or anything one uts on the 30psi it'll engage but not turn kff when there's too much I do have a recovery machine so it's a bit time consuming but I'm trying to figure ut out but as it idles the psi will slowly slowly go up noticeably and I can't seem to understand what I'm missing throughout this problem please any help would be appreciated

I'm having a hard time making sense of this. A clearer description might help. (I don't know what "one uts on the 30 psi" is referring to.) I thought you said previously that the compressor clutch was receiving power but not engaging. This now appears to be a completely different description of what's going on.
The clutch won't engage at all I was implying once it's at 30 psi the fan will kick on to register the freon but it'll will not turn off if it's more then it's needed
First thing you need to do is address the clutch issue. You can double-check whether it operates at all by applying +12V directly to the clutch coil. If the AC clutch doesn't work then nothing else will.
@chucktobias okay I wasn't able to check the clucth but I did get a used one and we'll when I tool the old one off all the oil was bubbling like foamy I also would wanna point out the condensor is damaged and I would like to know what should I switch out cause I'm sure the previous owner never did maintenance to the car
okay I wasn't able to check the clucth
Checking the clutch is very simple, all you need to to is connect +12V to the clutch wire and see if it activates.
I did get a used one
A used 17-year-old compressor might well be worse than what you have now and even if it does work may have a short lifespan ahead of it.
I also would wanna point out the condensor is damaged and I would like to know what should I switch out
Obviously replace the bad condenser. Probably a good idea to replace the drier as well, also any hoses that look questionable.
You should dump out and measure the oil from your original compressor. Then dump out oil from the used compressor and put in the same amount of fresh oil as came out of the old compressor. If there is any indication of contamination in the oil from the used compressor such as metal flakes indicating internal wear, don't use it. If you contaminate your AC system with debris you'll have bigger problems.
You will also need to add oil to make up for what was in the condenser and drier. Below is what Honda recommends. The drier should be installed last, just before pulling vacuum. Be sure to use the correct weight of PAG oil and don't put in too much since it will reduce cooling.
@chucktobias can my damaged condensor affect my clutch bc I'm buying the clutch and replacing that along wuthering the condensor and dryer
@usgxviper I don't see how, other than if the condenser leaked out your refrigerant the low-pressure safety switch would not allow the compressor clutch to engage.
07 honda accord
Has a new ac clutch
And consented
Put two cans r134a one from Walmart one from a random store only put a out 30 psi on cold
And it just stopped working it's warm as clutch is spinning sluggy and low side is on 120 and high is on 125
Plz help

Did you pull vacuum and then actually measure how much refrigerant was added? Did you change the drier? Add a small amount of PAG oil to make up for what was lost in the replaced components?
The amount in those cans can vary, as well as the amount you can actually get out of them. To get an accurate refrigerant charge the cans need to be weighed while charging. In modern AC systems you need to be within a few ounces of the specification for proper operation.

Those pressures indicate your compressor is not doing much of anything. See the diagnostic chart in the link below:
@chucktobias hey okay so It's cold currently but I wanna know if 25L/190H is okay
@usgxviper That depends on ambient temperature. Have you consulted an R134a pressure chart?
