Hello.
Please anybody can help me, I have problem with my air conditioning on Accord 2.2 i dtec 2009. Yesterday i got recharged my A/C. But sadly after recharge my A/C still doesnt work, when i turn on ac revs rise a bit and ventilators turns on, but ac clutch not engage. I have read forum about A/C problems but every post with photos are old and i cant see photos. I have checked all fuses and swaped relay but no change. Any tips? sorry for my english.

Sounds like too much pressure in the system. Perhaps there’s a blockage somewhere like the condenser, have you tried flushing it out? Does the fan kick in when the compressor engages?

I’m no Aircon expert but these systems aren’t that complicated, once you understand what each component does. If the compressor is kicking in and so is the fan when you engage the aircon then that suggests both your pressure sensor and compressor are working, and there is sufficient gas in the system with no major leak. The fact both pipes are hot is what you probably need to investigate, something is stopping the gas from being pumped freely. Are there any kinks in the pipe work or a flange connection not sat correctly restricting the flow?

probably worth searching the net to see what might cause this, as someone on another forum (doesn’t have to be Honda) May have had the same issue

hello.
Yesterday I was at only AC repair shop. They tested it and said that high pressure is too big and low presure in vacuum -1 or something like that I dont remember sorry. They told me that expansion valve is problem 99%. They also told that valve isnt original, so valve is for other honda, or its faulty or clogged. They gonna replace expansion valve next week + flush pipes and replace ac receive drier.
Please owners of accord 2.2 i dtec can anyone post here photo of your original AC expansion valve, its next the shock mount. Thanks so much.
