well, i found a hose leaking after all that. it's one a po had made. i have ordered the correct hose from the stealership. since i have to go back into the system, should i just convert back to r12? do i have to flush all the oil out or is ester oil compatible with r12? i'm just so frustrated. all i want is cold air.......

thanks
