Hey all, before I give up and take my 2009 civic to a shop, I thought I'd ask around here. My AC was not blowing cold air so I took a look at the compressor clutch which was not spinning. After much research on youtube I decided to change out the clutch assembly (coil, pulley, and clutch plate). Still not working. When I first start the car cold, it'll engage for a good 15 seconds but then disengage. Then it'll engage for like a second and disengage and continue to do this. I don't think it's the relay cause I changed the clutch one out. I used one of those DIY ac/pro canister w/gauge and the low side reads about 30 psi when the clutch engages. Could it be cause it's low on refrigerant? Is my compressor about to die? I have run out of ideas. Thanks for any help.

what procedure did you use to fill the refrigerant?
I would have tried that before changing the clutch, BTW...

I did recharge the refrigerant before deciding to change out the clutch. I used one of those acpro canisters you get at oreillys. Attached it to the low pressure side and filled it up. Used up the whole 12 oz.

did you keep the engine/AC running while filling? I saw many make this mistake

yessir, I had the engine running and ac turned on. The cheapo gauge that comes with the canister only reads properly when engine is running.
