I have a 2007 2500hd LT with 149k on it. Truck runs mint I have Efi live and a few other upgrades nothing crazy. I have been having problems with the ac recently. The compressor clutch wasn't engaging I went threw the entire system jumped the relay to see if everything worked had the system vaccumed and recharged no leaks to be found. The other day I pulled all the fuses under the hood and fuses in cab and then the compressor clutch and ac system started to work again blowing cold air just as normal. This lasted three days and then it went out again and didn't work. I'm lost and need some help anything ideas are appreciated thank you!
