Scotty I have Acura csx 09 ( fancy honda civic) it was made specifically for Canadian markets; my A/C clutch is not engaging, I have pressure fans are working, when I turn ac on the interior light becomes less bright for a sec, I checked A/C compressor relay and it was broken, when I Shake, I can hear broken plastic sounds inside the relay, I replaced that still didn't fix the problem, I switched relies but nothing happened, heat works perfectly fine, the way I tested pressure is unscrew the low ac pressure cap and push the pin inside, and pressure comes out ( air) not cold though?? 

Note : A/C clutch is sticking out little bit, comparing to other cars I compared them to on YouTube, what could it be ?

Thanks
