Hi, on my 03 civic, the compressor clutch and condenser fan do not engage when I press the AC button , here is the test I have done

-all my relay and fuse are tested and are good

-I have jumped the condenser fan from the fuse box and it does turn

-I have jumped the compressor clutch from the fuse box and it engage and it blow cool air inside the car but the idle stay the same

-I have unplug the pressure switch jumped the 2 wire together and then try to pu AC on but nothing happen



so the compressor and fan are good but it does nothing when I press the AC button.. it seems that there is no power going to the relay to activate

what is the next test I can do ?? thanks

I'm having the exact same issue. 02 JDM EP3. Exactly the same problem and my local Honda garage are lost with whats causing it. They actually told me to google it, which brought me here

 

You'll need a schematic for your car, if you can find one, I will help you to the end.
